• Why Care About Your Crusher's Feed Cone Assembly?

  Apr 16, 2026

  Ever wonder which component takes the first hit before your mantle even touches the rock? Most people point to the mantle and bowl liner—after all, those are the parts that actually do the crushing. But look up. Sitting quietly at the very top of the crusher is a small yet vital component: the feed cone assembly. Without it, even the best crusher would struggle to perform efficiently. What Is a Feed Cone Assembly?The feed cone assembly, also known as the feed plate or distribution cone, is installed on the locking bolt at the very top of a cone crusher’s crushing chamber. There is typically one feed cone per machine, and it sits directly above the mantle and bowl liner, making it the first component that incoming material touches. Its funnel‑like shape is designed to receive falling rock, ore, or aggregate and guide it smoothly toward the center of the crushing chamber, from where the material spreads out evenly before reaching the crushing surfaces. Key Components of a Feed Cone Assembly Lock nut: Secures the entire assembly to the top of the crusher, preventing loosening under vibration. Feed cone: Manufactured from MN13Cr2 high manganese steel, it distributes incoming material evenly across the crushing chamber, controls feed speed to match crusher load, and reduces direct impact on the mantle and bowl liner for balanced wear and efficient crushing. Hex bolt: Fastens the feed cone firmly to the mounting base for stable operation. Spring washer: Maintains bolt tension and absorbs shock to avoid loosening during crushing. Sealant: Seals the mating surfaces to prevent dust, fines, and moisture from entering the joint. What are the Parts Included in the Feed Cone Assembly?Eg: HP400 ONA-N90058315   Pos.

It controls feed rate to match crusher load, avoiding clogging or starvation. It absorbs impact energy from falling rocks, protecting the mantle, head, and torch ring from direct strikes and extending their service life. The Feed Cone – The Heart of Your Feed Cone AssemblyWithout the feed cone, the entire feed cone assembly loses its purpose. It is the key component that evenly distributes incoming material into the crushing chamber, protecting the mantle and bowl liner from uneven wear and impact damage.The following is a list of feed cones suitable for Metso, Sandvik, Symons, Nordberg, and Barmac crushers:  What Models of Feed Cone Do You Offer?

A damaged feed cone leads to uneven feed, accelerating liner wear, reducing product consistency, and risking damage to the head and top shell. Replacing a feed cone is quick, easy, and far cheaper than replacing liners prematurely or repairing the crusher frame. Regular inspection pays big dividends.

• What Is a Lower Frame Assembly and Why Can’t You Ignore It?

  Apr 09, 2026

  A cone crusher relies on several structural assemblies, and the lower frame assembly is the solid foundation that supports everything above it. Sitting at the very bottom of the crusher, it holds the eccentric bushing, the main shaft, and the hydraulic adjustment components. It also contains the main lubrication channels that keep internal parts running smoothly. Without a robust lower frame assembly, the entire crushing process would become unstable and unreliable. In simple terms, the lower frame assembly is the ankle and foot of the crusher. It takes all the load and keeps the machine standing tall. What is the Lower Frame Assembly?The lower frame assembly is the lowest major structural part of a cone crusher, typically cast from high-strength steel or ductile iron. It serves as the main base that connects the crusher to its supporting foundation, while also providing precise mounting surfaces for critical rotating components. Inside this assembly, you will find the eccentric drive mechanism, the main shaft socket, and the oil distribution system. Unlike the upper frame (which handles the feed and initial crushing), the lower frame assembly deals with transmitting crushing forces down to the foundation and housing the drive gear train. In many designs, the Lower Frame Assembly also incorporates hydraulic cylinder mounting points for adjusting the closed side setting (CSS).   Key Components of a Lower Frame AssemblySeveral key components work together inside the lower frame assembly. Here are four of the most important ones: Lower Frame: This is the main cast body that supports all other components, absorbs crushing forces, and mounts the crusher to its foundation. Countershaft Assembly: This unit transmits power from the drive motor to the eccentric bushing via the pinion and large gear, enabling the gyratory motion. Thrust Bearing: This component carries the entire axial load from the main shaft and eccentric, preventing metal-to-metal contact and ensuring smooth rotation. Eccentric Bushing: This rotating part fits within the lower frame bore and provides the main shaft with its gyratory motion. It is driven by the countershaft pinion and directly supports the main shaft socket.   What are the Parts Included in the Lower Frame Assembly?Eg: GP200 ONA-MM0309979   Pos.

The most common issues include cracks in the casting (often due to tramp iron or overloading), worn eccentric bushing (causing abnormal gyration and power spikes), and gear tooth pitting or breakage (leading to noisy operation and inaccurate CSS adjustment). Oil leaks around the lower frame assembly seals are another red flag, as they indicate seal degradation or a distorted mating surface. Regular visual and dimensional inspections are essential – especially after any tramp iron event.    Maintenance Tips for the Lower Frame AssemblyTo extend the life of your lower frame assembly, always follow the manufacturer’s lubrication schedule. Use the correct oil viscosity and keep the oil clean, because dirt is the number one killer of eccentric bushings and gears. During maintenance, check the mounting bolts between the lower frame assembly and the foundation – loose bolts can cause frame fatigue cracks. Also, inspect the sealing surfaces when replacing the lower frame assembly liner or dust seal. If you notice any cracks in the casting, do not weld it without professional advice; some cracks can be repaired, but many require full replacement for safety.   When Should You Replace the Lower Frame Assembly? Unlike wear parts (such as mantle and bowl liner or concave mantle for cone crusher), the lower frame assembly itself is not a consumable component. However, replacement becomes necessary when: The main bore for the eccentric is worn beyond spec. The casting has developed a critical crack that affects structural integrity. The mounting surfaces for hydraulic cylinders are damaged beyond repair. In many cases, a worn lower frame assembly can be rebuilt by line-boring and installing new bushings, but severe damage means replacement is more cost-effective and safer.

• What is the counterweight assembly?

  Mar 31, 2026

  In the high-stakes world of aggregate and mining processing, the efficiency of your cone crusher relies on the seamless integration of its components. Among these, the counterweight assembly plays a critical role in ensuring smooth operation by balancing the dynamic forces generated during crushing. For operators using HP series equipment, sourcing high-quality hp crusher wear parts is essential, and the counterweight assembly is a key part of that system, directly impacting machine stability and longevity. What is the Counterweight Assembly? The counterweight assembly is a crucial mechanical component designed to offset the centrifugal force created by the eccentric bushing and the crushing head during rotation. By providing this dynamic balance, it significantly reduces harmful vibrations that would otherwise stress the main frame and other structural elements. For professionals seeking reliability, partnering with a trusted supplier of china metso crusher wear parts ensures that this assembly maintains the precise weight and dimensional tolerances required for optimal machine performance.   Key Components of a Counterweight Assembly A high-quality counterweight assembly is composed of several precisely engineered parts working in unison: Counterweight: This is the main cast iron or steel body, precision-machined to a specific weight that dynamically balances the crusher’s gyrations. Counterweight Liner: A sacrificial wear plate, often made of high-strength steel or rubber, that protects the main counterweight body from material buildup and abrasion. Hexagonal Screw: These high-strength fasteners are used to securely mount the counterweight liner to the main body, ensuring no loosening under extreme vibrational forces. Silicone Seal: A flexible sealing element that prevents fine dust, moisture, and debris from infiltrating the counterweight area, which could lead to premature wear or imbalance. Hard Thread Locker: A chemical adhesive applied to the threads of the screws to create a vibration-proof bond, preventing critical fasteners from backing out during operation.   What are the Parts Included in the Counterweight Assembly? Eg: HP400 ONA-7090228112 Pos. Part No. Description Qty Net wght 1 7016200114 COUNTERWEIGHT 1 739 2 1038018156 COUNTERWEIGHT LINER 1 143 3 7001530410 HEXAGONAL SCREW 8 0.13 4 MM0361376 THREAD LOCKER 1 0.2 5 7001530432 HEXAGONAL SCREW 6 0.4 6 7008010040 SILICONE SEAL 1 0.36   Why Precision in Balancing MattersThe primary function of the counterweight assembly is to manage the machine’s inertia. In a cone crusher, the rotating eccentric creates a powerful unbalanced force. Without a properly weighted and assembled counterweight, this force manifests as excessive radial runout and “hammering” on the main frame. A precision-engineered counterweight assembly ensures the crusher’s rotational forces are neutralized, allowing the machine to run smoothly at its rated speed. This directly translates to higher throughput and prevents premature fatigue failures in the main shaft and bushings.   Signs of Counterweight Assembly Failure Given that the counterweight operates in a high-stress, rotating environment, regular inspection is vital. Common indicators of a failing counterweight assembly include unusual vibrations that can be felt in the crusher’s base frame, excessive noise from the lower section of the crusher, and premature wear on the main shaft bushings. Additionally, if the silicone seal is compromised, operators may notice an accumulation of dust or “fines” packed tightly around the counterweight area, which can lead to an imbalance condition and catastrophic wear if left unaddressed.   Our Full Range of Counterweight Assemblies We offer a comprehensive range of aftermarket counterweight assemblies engineered to meet or exceed OEM specifications for durability and balance.  The following is a list of the main counterweight assemblies suitable for Metso cone crushers: Brand Cone Crusher Models Part No. Suit Metso HP4, HP6, HP200, HP300, HP400, HP500 N98000229, N98000228, N98000263, N98001181, MM1375731, N90228114, N90228115, 7090228201, N90228304, 7090228112, N90228127, 1093055003, N90228024   Ensure Your Crusher’s Balance and Longevity The counterweight assembly may not be the most visible part of your cone crusher, but its role in maintaining dynamic stability is non-negotiable. By investing in high-quality, precisely balanced assemblies and genuine components like silicone seals and hard thread locker, you protect your entire crushing circuit from destructive vibrations.

• What is the main shaft assy?

  Mar 24, 2026

  It is the single component that holds your cone crusher together—literally. The Main Shaft Assembly is the structural core of your crusher. It supports the mantle, drives the crushing motion, and absorbs the immense forces generated when breaking rock. Without it, your crusher is nothing more than a steel shell. While mantle and bowl liner handle the daily wear, the main shaft assembly determines whether your machine runs reliably for years or becomes a recurring source of unplanned downtime. It is the difference between a crusher that delivers consistent production and one that keeps your maintenance team busy. In this article, we’ll walk you through what the main shaft assembly is, its key components, and the manufacturing standards that ensure it performs as reliably as—or better than—any original equipment. What Is the Main Shaft Assy? The main shaft assembly is the central load-bearing and motion-transmitting component in a cone crusher. It serves two critical functions: Structural support: Carries the mantle and transmits crushing forces into the crusher frame Motion generation: Delivers the gyratory movement that creates the crushing action Designed for a service life measured in years—not hours—the main shaft operates under extreme conditions: high cyclic loads exceeding several hundred tons, shock loading from tramp material, and continuous exposure to dust, vibration, and temperature fluctuations.A main shaft assembly is not a single piece. It is a precision assembly of multiple components that must work together with exacting tolerances. Any deviation in geometry, material integrity, or assembly procedure directly affects crushing efficiency and operational uptime. Key Components of a Main Shaft Assembly HEAD: The main body that supports the mantle. Mounts to the main shaft via precision taper fit, providing the foundation for the crushing surface. MAIN SHAFT: The central structural member. Transmits eccentric motion to the head and supports all crushing loads. Forged from high-strength alloy steel with precision-ground bearing surfaces. PROTECTION BUSHING: Fits over the main shaft to provide the bearing interface between the shaft and eccentric bushing. Prevents direct metal-to-metal contact and maintains proper oil film clearance. SEAL: Prevents dust, water, and contaminants from entering the bearing surfaces and lubrication system. Essential for maintaining oil cleanliness and component life. LOCK WASHER: Prevents loosening of threaded connections under vibration. Provides a consistent clamping force and must be replaced after each disassembly. HEXAGON SOCKET HEAD CAP SCREW: Secures critical components such as the protection bushing and locking mechanisms. Requires precise torque application to withstand cyclic loading.   What are the parts included in the main shaft assy? Eg: GP200 ONA-MM0310111 Pos.

• What is the pitman assembly?

  Mar 19, 2026

  If you work with jaw crushers, you have likely heard the term Pitman Assembly (or moving jaw assembly). But what exactly is it, and why does it matter? In this short guide, we will break down the basics and show you the full range of pitman assemblies we offer. What is a Pitman Assembly? The pitman assembly is the moving part of a jaw crusher. It houses the pitman (the main body), the jaw dies, jaw crusher toggle plate, and bearings. As the eccentric shaft rotates, the pitman moves back and forth, crushing material against the fixed jaw. It is the heart of the crushing action – without a robust pitman, your crusher can not perform.   Key Components of a Pitman Assembly Pitman body : The main structure that transfers crushing force. Eccentric shaft: Drives the pitman’s reciprocating motion. Bearings: Ensure smooth rotation of the eccentric shaft. Bearing housings: Support and protect the bearings. Labyrinth seals: Prevent dust and dirt from entering the bearings. What are the parts included in the pitman assembly?Eg：C125 ONA-910869   Pos.

• What is the crusher hammer head?

  Mar 17, 2026

  When we talk about hammer crusher spare parts, the most critical component that comes to mind is the hammer head. It is the heart of any crushing operation—the part that actually does the breaking. Whether you are running a stone crusher in a quarry or recycling materials, understanding this simple yet vital piece can save you thousands in operating costs.   What Exactly Is a Crusher Hammer Head? A crusher hammer head is a wear-resistant component mounted on the rotor of a hammer crusher. As the rotor spins at high speed, the hammer head swings out and strikes the fed material—limestone, coal, gypsum, or demolition debris—breaking it into smaller pieces. Think of it as the “teeth” of the crusher; without it, no crushing happens.How Does It Work?The working principle is simple but powerful: Impact: The hammer head hits the incoming material with tremendous force. Crushing: The material is shattered against the breaker plates or other rocks inside the crushing chamber. Discharge: Once the pieces are small enough, they pass through the grate bars at the bottom. Because the hammer head takes the brunt of the impact, it is classified as a wear part—it will eventually wear out and need replacement. That’s why choosing the right crusher parts is essential for maintaining production efficiency. Common Materials for Hammer Heads Not all hammer heads are created equal. Depending on what you are crushing, the metallurgy should change. Here are the three most common types used in stone crusher applications: High Manganese Steel: Excellent toughness; work-hardens under impact. Common grades include Mn13Cr2, Mn18Cr2, and Mn22Cr2 – with higher manganese content providing greater work-hardening capacity for severe impact conditions. Ideal for large, hard rocks like granite. High Chrome Iron: Extremely hard and wear-resistant; lasts 3–4 times longer in abrasive conditions (e.g., silica-rich materials). However, it is more brittle. Bi-Metal Composite: Combines a tough steel shank with a wear-resistant alloy head—offering both safety for the rotor and long wear life. When Should You Replace Them? Even the best hammer heads wear down over time. Running a worn hammer too long leads to: Reduced crushing efficiency Higher energy consumption Risk of damaging the rotor (which is 10x more expensive to repair) This is where having a new vs. worn comparison becomes valuable. Look at the image below: the hammer on the left is new, with a full profile. The one on the right is heavily worn and must be replaced immediately.Simple Maintenance Tips to Extend Life Rotate Regularly: Wear is uneven. By flipping or swapping positions, you can use the full mass of the hammer and increase service life by up to 50%. Check for Cracks: A cracked hammer can break apart and damage the crusher. Inspect them weekly. Remove Tramp Metal: Install a magnetic separator. One stray piece of steel can destroy an entire set of hammers.   Why the Right Hammer Head Matters As a hammer crusher spare part, the hammer head directly affects your bottom line. The initial purchase price is only part of the equation—what really counts is cost per ton crushed. A hammer that lasts twice as long, even if it costs a bit more, almost always delivers better ROI.Whether you are a purchasing manager looking for the best value or a maintenance engineer trying to keep the plant running, understanding the basics of hammer heads helps you make smarter decisions.   Need Help Choosing?

• What is a wrecking ball?

  Jan 04, 2026

  A wrecking ball is a heavy steel ball suspended from a crane that is used for building demolition. Wrecking balls supplied by ONA are characterized by quality cast steel with excellent durability, helping to reduce overall operating and production costs.When breaking pieces of stone larger than the entry hole in the quarry, crushers can easily use energy balls falling from the height on the stone or to let stone hit the ball. ONA provides several sizes and weight categories for balls, we are willing to advise you with the selection. Detailed introduction Product Name Wrecking Ball Material ZG 270-500 Thickness ≤100mm Tensile Hardness ≥500Mpa Molding Process Casting, Heat Treatment, Finish Machining Payment L/C, Western Union, D/P, D/A, T/T, MoneyGram Lead Time 4 weeks Chemical Component ZG 270-500 Material C Si Mn S P Ni Cr Cu Mo ≤0.40 ≤0.50 ≤0.90 ≤0.04 ≤0.04 ≤0.30 ≤0.35 ≤0.30 ≤0.20 ρ(7.85) Diameter(m) Volume(m^3) Weight(ton) 1 0.52 4.11 1.3 1.15 9.03 1.31 1.18 9.24 1.32 1.2 9.45 1.33 1.23 9.67 1.34 1.26 9.89 1.35 1.29 10.11 1.36 1.32 10.34 1.37 1.35 10.57 1.38 1.38 10.8 1.39 1.41 11.04 1.4 1.44 11.28 1.41 1.47 11.52 1.42 1.5 11.77 1.43 1.53 12.02 1.44 1.56 12.27   Core Components and Working Principleon  1. Sphere: Typically made of high-density cast steel (such as the ZG270-500 you mentioned), with a diameter ranging from 0.8 meters to several meters, and weighing several tons or even tens of tons. 2. Suspension System: Consists of slings, chains, and a release mechanism from a crane (or a dedicated demolition machine). 3. Working Principle: The operator manipulates the crane to lift the steel ball to a certain height. By swinging or directly releasing the ball, it accelerates along a "pendulum" trajectory to strike the target (such as walls, columns, or floor slabs). At the moment of impact, the ball's enormous mass multiplied by its velocity generates extremely strong kinetic energy, sufficient to crush concrete, brickwork, and other building materials, causing the structure to crack, break, and ultimately collapse.   Main Features 1.Immense power: Capable of quickly destroying sturdy reinforced concrete structures. 2.Simple structure: The equipment itself requires virtually no maintenance and is highly reliable. 3.Low cost: Compared to some high-tech demolition methods, the initial investment and operating costs are low. 4.Wide applicability: Particularly suitable for demolishing independent, tall structures such as bridges, chimneys, and large industrial plants. 5.No electricity/hydraulic power required: The ball itself requires no power, relying solely on a crane.     Modern Application Scenarios 1. Demolition of large industrial facilities: such as abandoned steel mills, power plants, cement plants, and other spacious factory buildings. 2. Demolition of bridge piers and abutments. 3. Controlled demolition of tall structures such as chimneys and water towers (by precisely impacting the base to cause them to collapse in a predetermined direction). 4. Secondary crushing: used to break up large concrete blocks after initial building demolition. 5. Emergency rescue: used for rapid demolition of dangerous structures on the verge of collapse after earthquakes or fires.   If you need to place an order, please provide detailed size information, including diameter and weight, and we can manufacture the product for you.

• What are the components of the adjustment ring assembly?

  Dec 29, 2025

  The adjustment ring is a core functional component of the cone crusher, enabling precise control of product particle size and overload protection.It is installed on the upper part of the main frame and is threaded onto the stationary cone assembly. Main Functions 1.Improving product quality: By precisely adjusting the discharge opening size, uniform particle size distribution is ensured. 2.Reducing maintenance costs: Automatic wear compensation extends the service life of the liner plates, ensuring the normal operation of the crusher and the stability of the product particle size. 3.Protecting equipment safety: When encountering unbreakable foreign objects that cause overload, the adjustment ring can move to release some of the pressure, preventing damage to critical components due to excessive pressure and further protecting the equipment's safety. 4.Installation and fixation: Providing the hardware foundation for remote monitoring and automated crushing, the adjustment ring plays a role in installing and fixing the stationary cone liner in the cone crusher. It provides a stable mounting base for the stationary cone liner.   What's parts included in the adjustment ring assembly？ Eg:HP300 ONA-7090248005         Pos Part No Description Qty Net Wght 1 7012504002 ADJUSTMENT RING 1 1830 2 7002122012 GREASE FITTING 4 0.01 3 7001548079 SCREW, SET, HEXAGON SOCKET, FLAT POINT 6 0.00871 4 1061873757 CLAMPING RING 1 290 5 7001530636 SCREW, HEXAGONAL 4 1.28 6 1094280065 CLAMPING CYLINDER ASSEMBLY 8 10.8 7 1002080430 ELBOW 1 0.03 8 1044250910 HOSE 1 0.1 9 1044251345 HOSE 7 0.1 10 1001998504 HOSE ADAPTER 1 0.00907 11 1001998508 CAP 1 0.045 12 7081108004 DUST SHELL 1 77 13 1063519182 SEAL 1 1.809 14 1022130525 BUSHING 6 1.25 15 N01530194 SCREW, HEXAGONAL 8 0.037 16 7001638012 WASHER, PLAIN 8 0.001 17 1002080450 ELBOW 1 0.227 18 7001626030 WASHER 4 0.06 19 7001548079 SCREW, SET, HEXAGON SOCKET, FLAT POINT 8 0.00871 20 1073044083 SPACER TUBE 4 0.6 21 7023604001 CAP, FOAM RUBBER 6 0.2 22 1064667128 CLAMP RING SEGMENT 6 2.2 23 N01530140 SCREW, HEXAGONAL 24 0.03 24 7001624010 WASHER 24 0.001 25 7001630010 WASHER, LOCK, SERRATED 24 0.00125 26 N01563010 NUT, HEXAGONAL 24 0.02   Would you like to learn more about adjustment rings?

• Whats about Bronze Copper Spare Parts？

  Dec 22, 2025

  When it comes to keeping your crusher running at peak performance, copper parts play a critical yet often understated role. These components, including eccentric bushings, socker liner, main frame pin bushing, trush washer/bearing and countershaft bushings are the quiet champions inside the crushing. Main components include: 1. Eccentric Bushing: Installed inside the eccentric steel sleeve, located on the outside of the main shaft. Its core function is to support and guide the movement of the eccentric shaft, protecting the main shaft and eccentric steel sleeve, preventing wear of the eccentric steel sleeve, and ensuring smooth and efficient crushing action. 2. Socker Liner: Installed at the top of the main shaft. Its working surface has oil grooves and mates with the spherical surface of the moving cone, supporting the entire conical main shaft and providing a low-friction spherical bearing, allowing the moving cone to swing freely. 3. Main Frame Pin Bushing: Installed inside the horizontal shaft housing, one at each end. Its main function is to prevent direct contact between the horizontal shaft and the inside of the horizontal shaft housing, providing lubrication (bearing) and protection. 4. Thrust Washer/Bearing: Divided into upper and lower thrust bearings. They work together under the action of a lubricating oil film, enabling the eccentric sleeve assembly to perform smooth eccentric rotational movement.   5. Countershaft Bushing: Installed in the horizontal shaft housing, one at each end. Located between the horizontal shaft and the inner wall of the housing, it provides lubrication and protection, preventing direct contact and wear between the two.     The following is a list of the

• What is a U/T type seal?

  Dec 15, 2025

  T-seals and U-seals are used as seals in cone crusher. They are made of imported polyurethane. 1.Superior Materials: Made with imported polyurethane, this material is wear-resistant, oil-resistant, and resistant to high and low temperatures, ensuring stable and reliable performance. The U-shaped seal is attached to the U-shaped seal groove on the main frame using a special adhesive and catalyst. 2.Precision Manufacturing: The U/T-shaped structure, combined with precision molding, provides excellent elasticity and a tight seal, preventing external dust from entering the equipment and preventing excessive leakage of lubricating oil during operation, thus providing further protection. 3.Wide Applicability: Perfectly matches various models of jaw crushers, cone crushers, etc.     U seal T seal 1063518780 HP200 1063518480 HP200 1063518815 HP300 1063518725 HP300 1063518943 HP400 1063518832 HP400 1063518950 HP500 1063518930 HP500 1063518530 HP800 1063518520 HP800 N53125506 HP3 1063518785 HP800 N53125503 HP4 N53125502 HP4 N53129005 HP6 N53128502 HP6   More Related Products SEAL RING O-RING SEAL KIT SEAL SET   The U/T seal is compressed during packaging, so the size upon arrival may differ from the picture.
