In the fields of sand and gravel aggregate production, mine crushing, etc., cone crusher has become the core equipment for medium-hard material processing with its efficient crushing capacity and stability. However, during the long-term high-load operation of the equipment, key components such as liner, mortar wall, crushing wall, main shaft sleeve, etc. are rapidly worn due to continuous impact, extrusion, and friction, which directly affects production efficiency and cost control. As a manufacturer focusing on the research and development of wear-resistant parts for 30 years, Zhili New Material company will deeply analyze the maintenance points of cone crusher wearing parts for you to help you achieve cost reduction and efficiency improvement!

• Four core wear parts of cone crusher-wear causes and failure effects

1. Cone crusher mantle and concave (moving cone/fixed cone liner)

Wear causes: direct contact with materials, high-frequency impact and sliding friction, and accelerated wear of hard materials (such as granite and basalt).

Failure effects: After the liner is worn, the particle size of the discharged material is uneven, the production capacity decreases by 20%-40%, and even abnormal vibration of the equipment is caused.

2. Spindle sleeve and eccentric sleeve

Wear cause: Long-term eccentric rotation pressure, insufficient lubrication or metal fatigue can easily cause the fit clearance to increase.

Failure effect: The equipment running noise increases, the crushing efficiency decreases, and in severe cases, the spindle breaks.

3. Material distribution plate and dustproof seal assembly

Wear cause: Material scouring and dust intrusion lead to uneven material distribution or seal failure.

Failure effect: Dust enters the lubrication system, aggravates internal wear and shortens bearing life.

4. Spring and hydraulic cylinder assembly (overload protection system)

Failure risk: Repeated overload impact can easily cause spring plastic deformation or hydraulic seal leakage.

Consequence: The equipment cannot automatically protect when overloaded, which may cause damage to core components.

• Why choose a professional wear-resistant parts manufacturer? ——Cost saving ≠ quality reduction

Many users choose low-priced non-standard accessories to reduce procurement costs, but face a vicious cycle of "frequent replacement-downtime loss-surge in maintenance costs". Take a granite crushing project as an example:

Poor quality lining: service life is only 400 hours, 8 replacements per year, and downtime losses exceed 120,000 yuan;

Zhili New Material High Manganese Steel Lining: life is up to 650 hours, saving 52,000 yuan in downtime costs per year.

• Zhili New Material Professional Manufacturer's Core Value:

✅ Material Innovation: Adopting modified high manganese steel, composite ceramic inlay and other technologies, the hardness is increased by 20%;

✅ Precise adaptation: Cast strictly according to the drawings, with small tolerances to ensure installation sealing;

✅ Full-cycle service: Provide regular maintenance recommendations to extend the service life of accessories by 30%.
