Our top-demand wear-resistant components and screening parts currently active in leading crushing circuits.
Precision-molded accessories and replacement spares engineered to exact site specifications.
Chema Engineers provides state-of-the-art modular wet processing systems and heavy-duty bucket wheel sand washers. Our solutions are designed for washing, grading, and dewatering river sand, crushed rock aggregates, and manufactured sand (M-sand).
Our plants integrate advanced hydrocyclone classification and high-frequency polyurethane dewatering screens. The closed-loop water management recyclers reclaim up to 95% of process water, helping quarries maintain environmental standards and optimize fine aggregate recovery down to 75 microns.
All-in-one washing, sizing, and dewatering platform built on a single, compact chassis. Reduces civil requirements, operates with minimal power, and fits onto compact sites. Shipped in pre-tested knockdown modules for fast commissioning.

View RollersFlocculant chemicals and chemical dosing systems designed to speed up water recycling in mining plants.
View SystemsOur polyurethane components are manufactured using a computer-controlled, open-cast chemistry process that maximizes molecule cross-linking. The result is a premium elastomer that outperforms traditional rubber and high-alloy steel in highly abrasive applications.
Advanced wear resistance lowers replacement costs and minimizes machine downtime in critical processing zones.
Precise aperture taper angles prevent material from sticking, maintaining high-throughput screening efficiency.
High tensile steel reinforcement bars are cast inside the polyurethane frame to manage heavy structural loads.
