Services
Sand Washing Systems
Our sand washing systems employ advanced cyclone technology to remove contaminants while recovering maximum fines. Designed for high-volume production, these systems produce saleable sand grades meeting industry standards. Modular units combine scrubbing, dewatering, and classification in single self-contained systems.
Mobile Washing Plants
Fully portable triple-axle mobile plants process materials to produce up to five saleable products. Integrated cyclone units with rubber-lined pumps enable efficient sand and aggregate washing. Ideal for short to medium-term projects requiring rapid deployment.
Water Treatment Plants
Water recycling systems achieve 90% water reuse rates through clarification and solids separation. Capable of treating 50-1,600m/hour slurry flows, these plants reduce freshwater consumption while maintaining operational efficiency in sand washing processes.
Complete Plant Solutions
Custom-engineered wash plants integrate screening, washing, and conveying equipment to meet specific production requirements. Systems combine automated controls with modular components for optimal material processing and operational flexibility across diverse applications.
Belt Feed Hoppers
Heavy-duty belt feeders ensure consistent material supply to washing and screening plants. Designed for high-volume throughput, these units maintain steady feed rates while handling challenging material characteristics for uninterrupted production.
