The main frame seat liner pad of the cone crusher is a critical part serving as a foundational buffer. Installed between the main frame and the equipment foundation (or base support), it is a vital wear part responsible for bearing the weight of the entire machine, cushioning crushing impacts, and isolating equipment vibration.
Application Scenarios: Mining, aggregate production, metallurgy, cement, hydropower, and construction waste recycling — for medium-to-fine and heavy-duty crushing.

Fault Symptoms and Countermeasures
Issue: Damage to the main frame seat liner.
Main frame seat liner welding issues often stem from poor process control. Follow these requirements:
Welding methodL:
✅ Thoroughly clean the welding area.
✅ Preheat to 100°C before welding.
✅ Weld from the center outwards.
✅ Maintain heat preservation for approximately 1 hour after welding.
The T237 welding electrode is a copper alloy electrode featuring an aluminum-manganese bronze core and a low-hydrogen sodium-type coating. The deposited metal is aluminum-manganese bronze, which offers excellent wear and corrosion resistance; it is primarily used for welding aluminum bronze and copper alloys to steel, as well as for the repair welding of cast iron.
Material Composition:
| Ai | Mn | Fe | Si | Cu | Pb+Zn | Ni | Pb | |
| Standard Value | 6.5-10.0 | ≤2.0 | ≤1.5 | ≤1.0 | margin | ≤0.50 | ≤0.50 | ≤0.02 |
| An example | 8.80 | 0.23 | 0.30 | 0.70 | 89.00 | 0.50 | 0.35 | 0.01 |
Mechanical properties of deposited metal
| Tensile Strength Rm (MPa) | Elongation A/% | |
| Standard value | ≥390 | ≥15 |
| An example | 470 | 31 |
Welding rod specifications and reference current (DC+)
| Welding rod diameter (mm) | 3.2 | 4.0 | 5.0 |
| Welding rod length (mm) | 100 | 350 | 350 |
| Welding current(A) | 120-140 | 150-170 | 180-200 |
⚠️ Warning
✅ Before welding, the electrodes must be baked at approximately 200°C for one hour. Moisture, oil, oxides, and other impurities must be removed from the surface of the workpiece prior to welding.
✅ When welding aluminum bronze to carbon steel, preheating is not required for thin sections, but thick sections must be preheated to approximately 200°C.
Packaging and Shipping
Given the characteristics of the main frame seat cushion—specifically its copper alloy material (prone to oxidation), substantial weight, and high precision requirements—we employ industrial-grade, multi-layer protective packaging (protective film, EPE foam, and solid wood crates) to prevent moisture, oxidation, and crushing damage. We offer options for self-pickup, dedicated vehicle transport, and full-truckload shipping, all with end-to-end tracking to ensure the product arrives in perfect condition with its precision intact.

FAQ
1. What is the function of the main frame seat liner?
It supports the adjustment ring assembly and provides a low-friction sliding surface to prevent contact wear; this offers protection and shock absorption, thereby extending the equipment's service life.
2. Under what conditions should it be replaced?
Binding or sticking during adjustment ring rotation; failure of the tramp iron release mechanism; stepped wear or scoring marks on the liner surface; or an increase in copper filings in the oil return filter element.
3. What are the requirements for installation and welding?
Thoroughly clean the welding area; preheat to 100°C before welding; weld from the center outwards; and maintain heat insulation for approximately one hour after welding.
The crusher feed cone is a key wear-resistant part designed to evenly distribute material, prevent uneven feeding and clogging, protect impeller liners, and improve the particle shape of the finished product.
