1. It is simple in structure, stable in performance, and has high wash degree, less loss in sand washing process, especially while transmission device is separated from water and sand, failure rate is greatly lower than recent sand washing machine, and it has long life span.

2. It has reasonable structure, innovative seal structure, totally sealed oil bath gear, adjustable overflow weir plate, which can guarantee products with high efficiency, durability, good washing and dehydration effect, and fine grain products are stable.

3. Great capacity and low power consumption.

4. It can save water resource and has little pollution.

5. It's easy to maintain.

The sand washing machine can be widely used in construction site, sand making factories, hydroelectric concrete dam subjects, concrete precast plant, oil pump filling and other industries. Its has high wash degree, reasonable structure, high capacity, small consumption, less loss of sand during sand washing, especially transmission part of the machine is separated from water and sand, its failure rate is greatly lower than the recent sand washers, and is an optimum equipment for replacing traditional ones.

This series sand washing machine is allocated with a tilt angle of 15º, the bottom of sink is surrounded by triangular weir plates forming a flow tank, the screw head is inserted into the tank and the screw will rotate continuously driven by motor through reducer. Fresh water is supplied from the multi-hole plate at the bottom of the flow tank. The equipment has three functions of washing, dehydration and grading.
