Zhili has served the global mining industry for over 30 years, partnering with mining companies in 50+ countries. Our advanced metallurgical systems — high-chromium cast iron, composite alloys, and heat-treated wear-resistant steels — deliver 2-5 longer service life compared to conventional materials.
The mining industry is one of the most demanding applications for wear parts. Ore hardness varies from soft limestone (Mohs 3) to extremely hard granite and quartzite (Mohs 7+), with high abrasive mineral content and large daily processing volumes. Crushing equipment — jaw crushers, cone crushers, hammer crushers, and gyratory crushers — operates continuously under extreme impact loads and abrasive wear, making wear parts the highest recurring cost item for mining operations.

Our advanced metallurgical systems — high-chromium cast iron, composite alloys, and heat-treated wear-resistant steels — deliver 2-5× longer service life compared to conventional materials, significantly reducing downtime, spare parts inventory, and total cost per tonne of ore processed.
High-chromium cast iron and composite alloy hammer heads with superior impact toughness and wear resistance for primary and secondary crushing.
Manganese steel and alloy jaw plates engineered for maximum toughness and impact resistance in primary jaw crushing applications.
High-chromium blow bars with advanced heat treatment for impact crushers. Optimized chemistry and microstructure for maximum wear life.
Precision-cast cone crusher liners with optimized wear profiles for consistent product shape and extended change intervals.
Large gyratory crusher wear parts with superior structural integrity for high-throughput primary crushing applications.
High-strength grate plates with optimized bar spacing for precise size classification and superior structural durability.
High-chromium cast iron is the gold standard for impact-crushing applications. Zhili's proprietary alloy design with Cr 18-28%, Mo, V, and Nb additions creates a refined carbide network that delivers exceptional abrasion resistance while maintaining adequate toughness for impact loading.
Austenitic manganese steel (Hadfield steel) undergoes rapid work hardening under impact and compression. The surface hardness increases from initial ~200 HB to 500-550 HB during service, creating a self-protecting wear surface ideal for jaw plates and cone liners processing large, unweathered ore.
Hot-rolled bimetal composite technology bonds a high-chromium white iron wear layer (HRC 60+) to a tough low-alloy steel backing. This combines maximum surface wear resistance with structural toughness, achieving weight savings of 30-50% compared to solid alloy castings.
Quenched and tempered low-alloy steels (e.g., 28CrMo, 35CrMo) offer excellent cost-performance ratio for moderate-abrasion applications. Precise heat treatment control delivers consistent hardness (HRC 44-52) with good toughness across large-section castings.
Large-block raw ore (≤1,200mm) processed by jaw crushers. Extremely high compressive loads and severe abrasive wear on jaw plates require maximum toughness with good initial hardness.
Medium to fine crushing of processed ore. Continuous abrasive wear from sliding mineral particles demands high chromium alloys with refined carbide distributions.
High-speed rotor with hammer heads impacting ore at 40-70 m/s. Combined impact and abrasive wear demands optimal balance of hardness and toughness.
Extremely high inter-particle comminution pressure (50-300 bar). The studded roller surface with tungsten carbide tips delivers maximum wear life in fine grinding circuits.
Ore grinding with high-pressure roller loading and high-velocity particle impact. Requires wear-resistant liners and grinding rollers with excellent hot abrasion resistance.
Continuous sliding abrasion from high-volume ore flow. Chute liners, bin linings, and feed hoppers experience severe wear requiring replaceable wear-resistant panels.
