Spiral Sand Washing Machine
This XL Series Screw Sand Washer delivers exceptional desliming and dewatering while integrating precision grading capability. Through coordinated control of the adjustable overflow weir and rising water velocity, users can flexibly regulate fineness modulus to control fine particle loss. The washer simultaneously performs primary classification of coarse and fine sand during washing, producing better-graded, higher-value final sand. Whether for high-quality M-sand or valuable mineral recovery from tailings, this machine achieves integrated washing and grading with low energy consumption, significantly enhancing overall
Key Advantages
1. Precision Grading & Adjustable Fineness Equipped with an adjustable overflow weir, it precisely controls fine particle loss by varying overflow height, enabling flexible adjustment of fineness modulus to meet diverse gradation requirements.
2. Integrated Washing-Grading & Simplified Process A single unit performs desliming, dewatering, and coarse-fine classification, replacing the traditional "washer plus screen" setup. This reduces equipment investment, footprint, and operating energy costs.
3. Enhanced Fine Sand Recovery Rate Optimized tank flow field design minimizes fine sand loss via overflow. Fine particle retention surpasses conventional washers, maximizing final sand yield while maintaining high cleanliness.
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.
