Spiral Sand Washing Machine
This 100-ton class Screw Sand Washer is the most widely adopted medium-capacity model, achieving optimal balance among investment cost, throughput, and operational stability. Featuring an optimized screw diameter and standard elongated tank, a single unit meets daily full-load washing demands of medium M-sand lines or ready-mix plants. Low-speed, high-torque screw agitation combined with an adjustable weir system precisely controls fine discharge, delivering low mud content and stable gradation—ready for C50+ high-grade concrete. It is standard equipment for mainstream aggregate processors.
Key Advantages
1. High Cleaning Rate & Fine Sand Recovery Optimized tank flow and weir design powerfully remove mud while keeping fine sand loss significantly lower than competitors, boosting finished product yield.
2. High Durability for Continuous Production Reinforced main shaft and high-torque gearbox endure extended non-stop operation. High-chromium alloy blades offer extended service life beyond standard materials.
3. Integrated Process Simplification A single unit performs washing, dewatering, and primary grading simultaneously. Low moisture discharge enables direct stockpiling without extra dewatering screens, reducing auxiliary investment.
Working Principle
The washer operates on the principle of gravity sedimentation and mechanical conveying. Installed at an incline, the motor drives the spiral shaft via a reducer. Material enters the water-filled tank where the spiral blades agitate and roll the sand, removing impurities through friction. Light impurities (clay/fines) overflow with water, while clean sand is conveyed upward for dewatering, achieving washing, grading, and dewatering in one unit.
Core Components
Washing tank is a welded heavy-duty steel plate with a semi-circular bottom; main spiral shaft consists of a hollow shaft and wear-resistant spiral blades; drive unit includes motor, pulley, and reducer to rotate the shaft; support frame provides robust stability; adjustable weir plate governs the washing and classification process.
