Zhili provides comprehensive wear solutions for the aggregate industry — from primary jaw crushing through secondary and tertiary cone/VSI crushing to final screening and conveying. We serve fixed crushing plants, mobile crushing contractors, quarry operations, and recycled aggregate processors across the globe.
The sand and gravel aggregate industry is one of the largest consumers of wear parts in the world. Billions of tonnes of aggregate are produced annually for concrete, asphalt, road construction, and building foundations. From river gravel to blasted rock, aggregate materials vary enormously in hardness, abrasiveness, and shape — and every crushing and screening operation needs the right wear parts to maximize throughput and minimize cost per tonne.
Zhili provides comprehensive wear solutions for the aggregate industry — from primary jaw crushing through secondary and tertiary cone/VSI crushing to final screening and conveying. We serve fixed crushing plants, mobile crushing contractors, quarry operations, and recycled aggregate processors across the globe. Our metallurgy is tailored to each crushing stage and material type, delivering measurably lower cost per tonne of finished aggregate.
Manganese steel jaw plates for primary crushing of river gravel, limestone, and blasted rock. Custom tooth profiles optimized for feed material gradation and desired product shape.
Precision-cast cone crusher liners with optimized wear profiles for consistent product shape. Available for all major brands — Metso, Sandvik, Telsmith, Cedarapids, and Chinese OEM models.
High-chromium blow bars for horizontal shaft impact crushers (HSI) in secondary and tertiary crushing. Optimized for maximum wear life in specific aggregate types — limestone, granite, basalt, or recycled concrete.
Vertical shaft impact (VSI) and hammer crusher rotor assemblies for sand making and fine crushing. Tungsten carbide insert options for ultra-abrasive granite and quartzite applications.
High-frequency screen decks, polyurethane screen panels, and rubber screen media for classification screens. Optimized aperture geometry for maximum throughput and minimum blinding in sand and gravel applications.
Chute, hopper, and feed bin liner plates with high-chromium bimetal composite surfaces. Custom-formed to match your specific geometry for quick, accurate installation.
The universal material for primary jaw plates, gyratory concaves, and cone crusher liners in aggregate crushing. Austenitic manganese steel work-hardens rapidly under impact — initial hardness of ~200 HB increases to 500-550 HB at the worn surface during service. This self-protecting mechanism makes it ideal for high-impact primary crushing of irregular rock lumps.
For secondary and tertiary impact crushing (blow bars, impact plates, VSI rotor parts), high-chromium cast iron is the standard. Zhili's HCrCI alloys with Cr 18-28% and optimized Mo-V-Nb microalloying create a refined M7C3 carbide network that delivers exceptional abrasion resistance at HRC 58-63, while maintaining sufficient toughness for impact loading.
For chutes, feed hoppers, and vibrating screen deck panels in aggregate plants, high-chromium bimetal composite (HRC 60+ wear surface metallurgically bonded to structural steel backing) delivers the highest wear life at the lowest weight. UHMWPE and rubber screen media are used for wet screening and anti-blinding applications.
For wet screening, anti-blinding applications, and noise-sensitive environments, polyurethane and rubber screen panels provide superior performance to steel wire screens. Polyurethane screens offer 3-5x longer life than steel, excellent release properties for sticky materials, and significantly reduced noise.
Jaw crushers processing large river gravel or blasted rock (up to 1,000mm feed size). Extreme impact loads and severe abrasion from angular rock fragments require maximum toughness — Mn18Cr2 austenitic manganese steel is the optimal choice.
Medium to fine crushing producing 0-40mm aggregate. Sliding and rolling abrasion from rock particles between concave and mantle at high pressure — requires excellent wear resistance plus good shape control.
Secondary and tertiary impact crushing for manufactured sand and shaped aggregate. Blow bars and aprons experience high-velocity impact with severe abrasive wear from fine rock particles — HCrCI is the standard solution.
Vertical shaft impact crushers for manufactured sand production from -40+5mm feed. Rock-on-rock or rock-on-iron configurations with extreme particle velocity (60-80 m/s). Tungsten carbide inserts on rotor parts for quartzite and granite.
Multi-deck vibrating screens classifying 0-5mm sand, 5-10mm, 10-20mm, and 20-40mm aggregate fractions. High-frequency screening at 800-1,000 rpm with abrasive rock causing rapid wear on screen media and deck frames.
Radial stacking conveyors, transfer chutes, and collection bunkers handling high volumes of abrasive aggregate. Chute liners and belt cleaner blades experience severe sliding and impact abrasion — bimetal composite is the proven solution.
