Customized Products—Liners, Hammers
Our Advantages
- Longer Service Life: Hardness up to HRC 58-68, service life extended by more than 30% compared to similar industry products.
- Outstanding Resistance to Damage: Precise regulation of elements ensures stability under high-frequency impact, extrusion, and friction. Excellent deformation resistance for liners and fracture resistance for hammers.
- Comprehensive Scenario Coverage: Supports customization of size, structure, and material parameters based on equipment models (Jaw crushers, Ball mills) and material characteristics.
- Higher Operating Efficiency: Streamlined liner design fits equipment walls to reduce energy loss; hammers use integrated molding with no weak welding points.
- Better Comprehensive Cost: Long life and low breakage rates significantly reduce replacement and downtime maintenance.
1.Wear-Resistant Steel Cylpebs—Reliable Partners for Grinding Conditions
Relying on years of R&D experience, Chengda liners and hammers select high-quality substrates like high chromium alloy and wear-resistant alloy steel. Using precise casting/forging processes and optimized heat treatment, and adjusting core elements like Chromium, Carbon, and Molybdenum, coupled with precision structural design (modular splicing for liners, optimized impact face arc for hammers), we achieve a perfect synergy of high hardness, strong toughness, and wear resistance.
