Introduction

Spiral Sand Washing Machine, also known as screw sand washer, is specialized equipment for washing, grading, and dewatering sand in various industrial applications. It adopts a long spiral structure that continuously stirs sand material in water, allowing mud, dust, and other impurities to be separated and discharged. This machine is ideal for processing sand with high clay content or fine silt, offering higher cleanliness and stronger adaptability compared to wheel type sand washers. Its robust design, large processing capacity, low energy consumption, and ease of maintenance make it a popular choice in sand production lines, mining operations, and infrastructure projects.

Working Principle

Sand material mixed with water enters a cleaning tank from feeding inlet. Inside tank, spiral shaft driven by motor rotates continuously. As spiral blades turn, they stir sand in water, allowing lighter impurities like clay, silt, and dust to be suspended and carried away through overflow outlet at top of tank. Meanwhile, clean sand settles to bottom and is gradually pushed upward along inclined spiral shaft by rotating blades. As sand moves up, excess water drains off through perforated plates or weep holes. Final cleaned and dewatered sand is discharged from outlet at upper end of spiral washer. This continuous and gentle cleaning process ensures sand is thoroughly washed with minimal loss of fine particles, making it suitable for high-quality concrete, construction aggregate, and other demanding applications.

Features

Application

Good Cleaning Effect

External sealing structure, fully enclosed oil bath transmission device, plus ingeniously designed spiral blades can effectively ensure the high-quality cleaning operation of the spiral sand washing machine, which can meet the requirements of high-g「ade materials

High Sand Washing Efficiency

Long spiral body & reasonable use of screw device to mix the slurry, which make the high degree of mechanization,compared with the wheel bucket sand washing machine, the processing capacity is larger, and the water content and mud content of the sand are lower

High Classification Accuracy

The professionally designed material guide plate and adjustable long overflow weir plate, combined with the optimized screw speed, can also wash materials with small particle sizes, effectively ensuring the accuracy of material washing and classification

Low Failure Rate

The spiral blades are made of compressive and wear-resistant materials, and the transmission part is separated from water and materials, so the failure rate is low, which effectively ensures the continuity of equipment work and reduces the cost of use
