• What is the Metso ES403 Vibrating Screen?

  Oct 20, 2026

  In a crushing production line, the ES403 serves a "sorting" function rather than a "crushing" one. As part of the Metso ES™ series of horizontal screens, it is responsible for precisely separating crushed material into specific product grades based on particle size. While its model designation might lead some to mistake it for a crusher, it is, in fact, a screening unit—typically positioned as the final quality control stage before the finished product leaves the site. The ES403 is a triple-deck horizontal screen with a deck size of 2,480 × 6,100 mm, providing a screening area of ​​14.6 m² (160 ft²). The unit has a total weight of approximately 16,500 kg and is driven by two modular exciters: an MV3 and an MV4.   Working Principle The Metso ES403 is part of the ES series of high-energy, horizontal vibrating screens with elliptical motion. The side plates are equipped with Metso MV™ modular exciters, driven by two counter-rotating eccentric shafts that impart an elliptical motion to the screen deck. Compared to conventional horizontal screens with linear motion, the elliptical vibration accelerates material stratification: fine particles settle and pass through the screen apertures, while larger particles are conveyed forward along the screen deck. The amplitude and frequency of the vibration can be adjusted to accommodate various operating conditions, including dry or wet materials, as well as sticky, prone-to-clogging materials.   Application Scenarios The ES403 is primarily designed for use in quarries, gravel pits, mines, and mobile screening plants. It is commonly employed for the final sizing of products, dry screening of cohesive materials, processing of solid waste, as well as wet screening or washing operations. It is not intended for material crushing; rather, it ensures that the final products meet the required size specifications.   Component Composition ES403 uses about 300 parts across six groups. First two are main wear parts; others impact service life and screening accuracy.   ✅ Excitation System—Includes the exciter, bearings, shaft, counterweights, and unbalanced segment assembly; determines the elliptical motion and amplitude.   ✅ Screening Surface System—Includes the screen media, screen frame, tensioning liners, and buffer bars; determines the product gradation and the service life of the screen media.   ✅ Structural Fastening—Includes side plates, cross beams, HUCK bolts, and torque-controlled nuts; maintains the integrity of the weld-free machine body.   ✅ Protection and Sealing—Includes dust seals, dust covers, and rubber skirting; protects the exciter and bearings.   ONA provides a long-term supply of screen deck supports, exciter components, impact bars, and structural fasteners for Metso ES series horizontal screens.

• What is the Metso SG60110 Gyratory Crusher?

  Oct 13, 2026

  The Metso SG60110 is a large gyratory crusher designed for primary crushing in mining operations and belongs to the SUPERIOR® 60-110 series. The designation "60" refers to a feed opening width of approximately 1,525 mm (60 inches), while "110" indicates a mantle base diameter of approximately 2,795 mm (110 inches). This series has evolved through three generations—MKI, MKII, and MKIII—with the SG60110 typically corresponding to the MK-II generation; the total weight of the unit is approximately 586 tonnes (based on the Phelps Dodge Morenci project unit, S/N S60110103).   The operating principle of the gyratory crusher is similar to that of the cone crusher: the main shaft drives the gyratory movement of the mantle (moving cone), causing the crushing chamber between the mantle and the concave (fixed cone) to open and close cyclically, thereby repeatedly crushing the material through compression.   This shows the modular shipping assembly and weight breakdown for the SG60110 unit.

• Are Your Cone Crusher Gears Noisy and Short-Lived?

  Oct 01, 2026

  Your cone crusher gears are getting louder and wearing out faster. Don’t replace them yet—check the meshing first. Loud noise usually means the large gear and pinion are not properly engaged. When noise drops, transmission becomes stable and gear life extends. How does ONA solve this with meshing tests, custom manufacturing, and strict material control? Why Gear Meshing Matters Cone crushers commonly use a large gear and pinion (bevel gears), not only suitable for Metso HP series but also suitable for Omnicone, Symons, MP, GP, and Sandvik CH/H models. Poor meshing causes: 1. Loud noise 2. High temperature 3. Rapid wear 4. Frequent downtime Noise is the most direct signal of meshing quality. The fit among eccentric sleeve, main shaft, and main frame directly affects meshing. Adjustment differs by model: 1. For Omnicones: push the eccentric sleeve toward the pinion. 2. For HP crushers: push the thick side of the eccentric sleeve toward the main shaft. ONA understands both gears and assembly logic—the basis for manufacturing to drawings.   Straight Bevel vs Spiral Bevel Gears Cone crushers mainly use straight bevel gears and spiral bevel gears. Intersecting-axis bevel gears achieve transmission efficiency of 98.0–99.0%. Straight bevel gears are simple with low axial force but noisier. Spiral bevel gears have higher contact ratio, smoother transmission, and lower noise—ideal for high-speed, heavy-load conditions. Choosing the right type is the first step to reducing noise. Straight Bevel Gears Spiral Bevel Gears Straight Bevel vs Spiral Bevel Gears ONA can produce both types to drawings and perform meshing tests. Noise level is verified after assembly. ONA’s Core Process: Listening to Noise ONA's meshing test logic is simple: loud noise means poor meshing; low noise means good meshing. This is based on repeated tests, not guesswork. A customer reported increasing noise and higher temperature. ONA engineers found poor meshing on the old gear. After replacing it with an ONA gear made to drawings and readjusting the eccentric sleeve and meshing clearance, noise dropped significantly and operation became stable. The before-and-after difference is clear.At no load, the meshing rate between gear and pinion is about 60%. Too low causes noise and wear; too high may cause rapid temperature rise. ONA does not deliver "close enough"—we confirm proper meshing by test. Low noise is not luck; it comes from material, cutting, grinding, and meshing tests. We retain meshing test traces for traceability. Gear Meshing Test ONA Gear Production ONA Spiral Bevel Gears Custom Manufacturing and Material Selection   ONA manufactures large gears and pinions to customer drawings or samples, with dimensions strictly meeting drawing requirements.

• How to Choose the Right Chamber for Sandvik CH870 Cone Crusher Liners?

  Aug 20, 2026

  The Sandvik Hydrocone H7800 crusher is a high‑capacity, heavy‑duty hydraulic cone crusher widely used in large‑scale quarrying, mining, and aggregate production lines. Its overall crushing performance, hourly output, finished product grain shape, and Sandvik Rock Crusher CH870 liner service life heavily depend on one critical factor: Sandvik Stone Crusher CH870 cavity selection. Most quarry operators commonly struggle with uneven liner wear, frequent crusher blockages, poor aggregate shape and unexpected downtime — very often caused by mismatched cavity profiles.   What Chambers Are Available for CH870?     EC Extra‑Coarse: Largest feed opening, deep receiving zone, secondary crushing, big feed material, pursue maximum throughput   C Coarse: Econdary / early‑tertiary, large‑medium feed size, high tonnage aggregate plant   MC Medium‑Coarse: MC Medium‑Coarse: Most‑popular general‑purpose cavity, balance of feed acceptance, capacity and product gradation   M Medium: Tertiary crushing, medium feed, produce well‑shaped 20‑31mm aggregates   MF Medium‑Fine: Fine tertiary, smaller CSS, cubical aggregate for concrete   F Fine: Pebble crushing & fine tertiary, limited feed size, small finished material   EF Extra‑Fine: Quaternary / pebble crushing, smallest allowable feed, ultra‑fine finished product     Core Rules to Select CH870 Chamber   Match crushing stage 1. Secondary crushing: Select EC / C: handle large incoming run‑of‑mine or primary‑crushed rock 2. Tertiary crushing: Select MC / M / MF, most aggregate production lines   3. Pebble /quaternary: Select F / EF, strictly control max feed size entering chamber   Feed size rule 1. Maximum feed entering crusher should not exceed 80% of cavity nominal feed opening. 2. If oversized material keeps feeding into a fine cavity: frequent bridging, blockage, rapid one‑sided liner wear.   Closed‑Side Setting (CSS) matching 1. Each cavity has its minimum working CSS. Do NOT run CSS smaller than cavity minimum value. 2. Running too tight CSS on coarse cavity leads to packing, high power draw and drastically shorten liner lifespan.   Material hardness 1. Hard, abrasive rock (granite, basalt, iron ore): choose slightly coarser cavity, avoid over‑crushing inside chamber. 2. Soft rock (limestone): can run relatively fine cavity for good product shape.   Typical Field Mistakes 1. Use one cavity for all conditions: keep using EC cavity when feed size drops, output fine product with poor grain shape. 2. Run fine cavity with oversize feed: liners wear uneven, frequent downtime. 3. Ignore eccentric throw cooperation: cavity profile must work together with eccentric throw to get target tonnage.

• What is a Crusher Pulley and Why It Matters？

  Jun 09, 2026

  Most people focus on concaves, jaw plates, and blow bars. The crusher pulley is rarely mentioned. But when the pulley fails, the whole crushing line stops. No power transmission means no crushing. At ONA, we manufacture high-quality crusher pulleys. Here’s what you need to know. A crusher pulley mounts on the input shaft. The motor drives it through V‑belts, and it transfers rotational power to the eccentric shaft or the countershaft. Without a pulley, there is no power. Without power, there is no crushing.   Why the Pulley Matters More Than You Think？ First link in the drive chain – A poor pulley causes vibration, misalignment, and belt damage. Dynamic balance requirement – An unbalanced pulley shakes the entire crusher, wearing bearings and loosening bolts. Belt and bearing protection – Worn grooves destroy belts quickly; misalignment overloads bearings.   What are the Parts Included in the Pulley? Eg：HP400 ONA-7068606761 Pos Part No. Description Qty Net Wght 1 ONA-7003234746 PULLEY, V-BELT 1 255 2 ONA-7003241824 HUB 1 25 3 ONA-1047009520 PARALLEL KEY 1 0.9 4 ONA-7015778304 BUSHING 1 2.3     Advantages of ONA Pulleys: Precision Machining – Strictly controlled according to OEM drawings for a perfect match. Dynamic Balancing Test – Verified before shipment for smooth operation. Dual Connection Methods – Keyway or tapered sleeve for easy installation without damaging the shaft. Full Range Compatibility – Covers mainstream brands of jaw crushers and cone crushers. Customization Service – Provide drawings, samples, or model numbers for precise production.     ONA Pulley ONA's pulleys are core transmission components designed specifically for jaw and cone crushers. They are not only available in a wide variety to perfectly fit the full range of models from mainstream brands such as suitablefor Metso and Sandvik, but also based on precision machining and reliable dynamic balancing to ensure stable and efficient equipment transmission. What Models of Pulley Do You Offer?

Replace the pulley if side wear exceeds 1 mm. Tighten taper lock bolts to the specified torque using a torque wrench. Align the pulley with the motor sheave using a straight edge or laser alignment tool. Listen for unusual wobble or clicking sounds during operation. Replace the pulley immediately if any crack is found.   The crusher pulley is a precision power transmission component. When it works well, you don’t notice it. When it fails, your production stops.

• Which Pump Does Your HP Crusher Really Need?

  Jun 04, 2026

  If you have ever searched for a replacement pump for your cone crusher suitable for Metso HP series, you may have noticed conflicting names: gear pump, hydraulic pump, and lube oil pump. Along with HP crusher wear parts, getting the right pump is essential for keeping your machine running. Which one do you actually need? Getting it wrong means ordering the wrong part and extending downtime. This short guide explains what each pump does, why they are different, and how to choose the right one. What Are the Two Pump SystemsThe HP series (multi‑cylinder cone crusher) has two independent fluid circuits. The lubrication gear pump circulates oil to the eccentric bushing, main shaft bearings, and gear set. The hydraulic pump supplies pressure to the clamping cylinders, tramp release cylinders, and the hydraulic motor that rotates the bowl for setting adjustment. Both are gear‑type pumps, but they serve completely different functions.Why the Difference MattersOrdering the wrong pump will not work. The lubrication pump runs continuously whenever the crusher operates; it provides relatively low pressure but high flow for cooling and lubrication. The hydraulic pump operates only when adjustment or tramp release is needed; it delivers higher pressure for cylinder actuation. Their mounting flanges, drive couplings, pressure ratings, and part numbers are different. Installing a hydraulic pump into the lubrication circuit will cause immediate failure – and vice versa. How to Identify the Right Pump for Your HP Crusher1. Check the symptoms and locate the pump Low oil pressure, high temperature or a noisy pump indicates a lubrication circuit problem, which means you need a gear pump (lube pump) usually mounted on the oil tank or crusher base frame and driven by an electric motor. Slow CSS adjustment, inability to hold clamping pressure or tramp release failure indicates a hydraulic circuit problem, which means you need a hydraulic pump, typically mounted on a separate hydraulic power unit. 2. Use the correct part numberWhether you need a lubrication pump or a hydraulic pump, for HP series or GP series, or any other brand, just provide your original part number. ONA will supply the exact replacement pump you need. No confusion, no wrong parts. The table below lists the part numbers of some best-selling lubrication and hydraulic pumps.

• Why Does Your Cone Crusher Need a Torch Ring?

  May 26, 2026

  When browsing crusher parts, most people focus on mantles and bowl liners. But there is a small component among cone crusher parts that, if ignored, can turn a routine liner change into a costly nightmare. That part is the torch ring – also known as the burning ring or spacer ring, depending on the brand. Do you know why it matters for your crusher parts inventory? Torch Ring: A Small Part with a Big JobIn cone crusher maintenance, the component that sits between the mantle lock nut and the mantle goes by different names depending on the brand. For the multi-cylinder HP series, it is commonly called Torch Ring. Suitable for Metso single-cylinder crushers, it is often referred to as the Spacer Ring. Suitable for Sandvik tends to use the Burning Ring, while suitable for Telsmith and suitable for Trio also have similar parts under various names. Regardless of what you call it, its function is the same: to act as a sacrificial spacer that allows safe removal of the mantle during liner change. Position of the Torch RingEg： ONA-1063915676 HP400 Pos.

• Does Your Jaw Crusher Need a Return Rod?

  May 22, 2026

  One single alloy steel rod keeps your toggle plate in place. When it breaks, your whole crusher stops. When discussing jaw crusher parts, most attention goes to jaw plates, cheek plates, and jaw crusher toggle plate. However, a small but vital component, the return rod or tension rod, is crucial for keeping the entire crushing mechanism intact. What Does the Return Rod DoThe return rod maintains constant contact between the pitman and the movable toggle plate, reducing impact wear. Each jaw crusher uses one rod, forged from high-strength alloy steel and heat-treated for strength and toughness. It works with a compression spring that pushes the toggle plate back after each stroke. Without proper tension, the toggle plate can slip, causing sudden crusher stoppage while the flywheel spins – a clear sign that the tension mechanism needs inspection. Return Rod Location in Jaw CrusherEg: C80  ONA-951199 Pos.

The most frequent failure is a bent or fractured rod. When the rod breaks, the tension spring loses its preload, allowing the toggle plate to shift or fall completely out of its seat. A worn or weakened spring can also cause rod failure, as increased dynamic loads elevate the risk of fracture. Both scenarios result in unplanned shutdown and immediate replacement. ONA Return Rods Engineered for ReliabilityONA manufactures replacement return rods from high-strength forged alloy steel, precision threaded to match original specifications. Each rod is 100 percent dimensionally inspected and coated with anti-rust oil.

• What Does the Countershaft Assembly Do in Cone Crushers

  May 14, 2026

  What Is Countershaft AssemblyIn any cone crusher, whether single cylinder or multi-cylinder, the countershaft assembly is the power transmission component that connects the drive motor to the crushing mechanism. It receives rotational energy from a V-belt or direct drive system and converts it into the controlled, powerful motion needed to break rock. Without a well-engineered countershaft assembly, even the finest crushing chamber cannot reach its full potential. What are the Parts Included in the Countershaft Assembly?Eg: HP400 ONA-N90018011 Pos.

The motor drives the pulley, rotating the countershaft; the bevel pinion meshes with the large bevel gear on the eccentric assembly, which rotates the eccentric sleeve and forces the main shaft to perform gyratory crushing motion. To withstand high-speed operation and extreme shock loads, every component is made from high-grade materials. The countershaft body is forged from 42CrMo alloy steel, quenched and tempered to 28‑32 HRC for strength and toughness. The bevel pinion and gear use 20CrMnTi carburizing steel with surface hardness 58‑62 HRC and a tough core. Bearings and bushings are precision‑machined bronze for stable support and heat dissipation.

• 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. Part No. Description Qty Net wght 1 N41060200 BOLT, LOCK 1 45 2 1055981158 FEED CONE 1 33.4 3 7001530880 BOLT, HEXAGONAL 1 2 4 7001632042 WASHER, SPRING 1 0.1 5 7008010040 SILICONE SEAL 1 0.36 Why Is It So Important? The feed cone assembly performs three critical functions that directly improve crusher performance and lower operating costs:  It spreads feed evenly across the crushing chamber, balancing forces, improving product consistency, and preventing uneven liner wear. 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? Suit Metso HPI00, HP200, HP300, HP400, HP500, HP700, HP800, HP3, HP4, HP5, HP6, GP11F, GP100, GP200S, GP300, MP800, GP100S, OMNI1560, GP550, MP1250, HP100, MP1000 Sandvik CH420, CH430, CH440, CH550, CH660, CH870, CH840, CH880, CH890, CH895, CS420, CS430, CS440, CS660, CV228, H2800, H3800, H4800, H6800, H7800, S2800 Barmac B9100SE, B9600, B6900, B7150 Symons 7FT Why You Should Pay Attention to Your Feed Cone Many operators inspect the mantle and bowl liner regularly, but ignore the feed cone until it is worn out. 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. The following is a list of the lower frame assemblies suitable for Metso and Sandvik cone crushers:   Brand Cone Crusher Models Part No. Suit Metso GP11F, GP300S, GP200, GP550 ONA-285374, ONA-MM0303333, ONA-MM0300550, ONA-MM0309855, ONA-MM0309979, ONA-MM0301555, ONA-586529 Sandvik H3800, CH430, S3800, H4800, CH440, H6800, CH660, H2800, CH420, S2800, S4800, H8800, NH200, NH300, NH400, NH400-9406, NH400-9642, NH400-9643, NH600, NH700, NH800, NS200, NS300, NS400-8067, NS600 ONA-442.7908-00, ONA-452.0231-01, ONA-442.7908-02, ONA-442.8735-00, ONA-452.3765-01, ONA-442.9871-00, ONA-452.9241-00, ONA-442.8735-01, ONA-442.9871-01, ONA-452.0231-02, ONA-452.0231-02M, ONA-452.0231-02C   Conclusion – Why It Matters The lower frame assembly might not be the most glamorous part of a cone crusher, but it is undeniably the most critical for stability and precision. Understanding its role, key components, and failure signs helps you plan proactive maintenance and avoid unexpected downtime. Whether you are an operator, a maintenance engineer, or a spare parts purchaser, treating the lower frame assembly with respect will pay off in longer crusher life and more consistent product quality.All names, marks, models, symbols and descriptions are used for reference purposes only and it is not impied that any of the parts/brands listed are the product of any company other than ONA.
