The spiral washer, also called the spiral washing machine, uses the spiral to push the stones to separate them from the water and soil, so the stones are clean, but its yield is slightly low. It is used for desliming and screening a large amount of sand and gravels used in construction sites, sand and gravel plants, prefabrication plants and hydroelectric construction sites, and it can also be used for ore sorting.
The spiral washer has a compact structure and a good design. It is mainly composed of a tank, reducer, motor, central shaft, spiral blade, and bracket. Its rack is welded on the central shaft, and the spiral blades are installed with bolts. The whole machine consumes fewer wearing parts and has a low cost of use.
The power device drives the impeller to rotate slowly after being decelerated by the V-belt, reducer, and gears. The sand and gravels enter the washing tank from the feeding tank to complete the cleaning. The clean sand is taken away and poured by the blades into the discharge chute from the rotating impeller to clean the sand.
Less failure rate
The impeller drive bearing device of the spiral washer is isolated from water and water-receiving materials, which greatly avoids damage to the bearing due to water, sand and pollutants.
High productivity and energy saving
The spiral washer can remove the impurities covering the surface of the sand and, at the same time, destroy the water vapor layer covering the sand to facilitate dehydration and wash the sand effectively.
The impeller drive bearing device of the spiral washer is isolated from water and materials, which avoids damage to the bearing due to water, sand and materials. In addition, the wheel sand washing machine adopts a fully-enclosed oil bath transmission device and an adjustable overflow weir plate, contributing to the high efficiency of production.
Good sealing performance
The spiral washer boosts a novel sealing structure, which has a better sealing effect, correspondingly contributing to a better cleaning effect and the long service life of the machine.
