What is a Cone Crusher Main Frame Liner?
Una trituradora de cono Revestimiento del marco principal is a heavy-duty, sacrificial protective casting mounted inside the lower mainframe body. Its primary critical function is to physically shield the expensive structural main frame from continuous, high-velocity abrasive rock impacts, fuerte fricción, and material scouring during high-tonnage aggregate processing. By absorbing intense multi-directional wear and preventing structural housing fatigue, una prima Revestimiento del marco principal extends the operational lifespan of the entire crusher assembly and protects your capital investment.

Ingeniería central & Ventajas técnicas
Because the mainframe inner walls sit directly in the severe path of raw aggregate flow, standard steel liners can wear through rapidly or crack under kinetic impact. Nuestra prima Revestimiento del marco principal replacements are proudly manufactured in China to deliver superior, heavy-duty durability:
Premium High-Manganese Steel: Cast from top-tier manganese alloys (such as Mn14Cr2 and Mn18Cr2) that continuously work-harden under heavy impact, maximizing surface abrasion resistance.
Absolute Dimensional Accuracy: Manufactured to exact OEM dimensional tolerances to match the exact profile of the main frame housing, ensuring a tight, vibration-free fit that prevents material from slipping behind the liner plate.
Advanced Casting Technology: Utilizes modern sand mold casting equipment backed by strict internal metallurgical testing on every production batch to eliminate micro-cracks and internal gas porosity.
Cost-Effective Wholesale Supply: Factory-direct production eliminates middleman markups, providing a high-ROI, easily replaceable wear layer for global mining and quarry operations.
Pautas de mantenimiento: When to Replace Your Main Frame Liner
Operating a crusher with a worn-through frame liner will directly expose the expensive main frame casting to destructive abrasive scouring and structural compromise. Recomendamos inspeccionar minuciosamente el Revestimiento del marco principal during major maintenance turnarounds:
| Enfoque de inspección | Señales de advertencia (Reemplazar inmediatamente) | Solución de mejores prácticas |
| Material Thickness | The manganese thickness has worn down past the critical service limit (typically reduced by 75%), risking breakthrough. | Reemplace el Revestimiento del marco principal immediately to prevent irreversible abrasive damage to the structural housing. |
| Physical Deformation | Severe cracking, bending, or structural fracturing across the shield body caused by massive tramp iron impact. | Swap the damaged guard to ensure continuous structural protection and prevent metal fragments from falling into the lower circuit. |
| Mounting Security | The liner rattles loosely during operation or shows worn, elongated mounting interfaces. | Pull the component. If the fit is compromised, replace it to prevent the liner from shifting and damaging the mainframe. |
