Spiral sand washer is a kind of efficient sand and gravel washing machine, which is widely used for sand and stone washing, grading and impurities removing. Spiral sand washers also called sand screw washers, are specifically used to produce quality sand for construction, highways, railways, glass making, water and electricity industries and more.

Spiral sand washing machine can be divided into single screw and double screw washing machine, and with the features of high cleanliness, good sealing structure, power consumption, fully closed transmission device, adjustable weir plate, durability, good dehydration effect, stability of finished product and more.

How screw sand washer work?

Screw sand washer is based on the principle of different specific gravity of solid particles and the different sedimentation rate in liquid to realize washing process. And is equipped with water spray pipes in cleaning tank. When working, a certain amount of water is supplied to flush and submerge the raw sand in cleaning tank from the inlet.

At the same time, the spiral is continuously stirred and graded, and dirt impurities, mud and tiny solid particles are suspended in the upper turbid water, gradually overflowing from the low-end overflow weir; the coarser sand particles sink to the bottom of the tank by gravity. As the spiral rotates continuously, the coarse sand is continuously agitated and graded in the water, so that the sand is fully washed.

Features

1. Reasonable structure, convenient maintenance, small power consumption. The novel sealing structure of the spiral stone washer, the whole sealing oil bath type transmission device and the adjustable overflow weir plate ensure that the series of products are durable, with good cleaning and dewatering effects, and the fine products are not disorderly.

2. Large processing capacity, because the screw sand washing machine sand washing principle is not to use a bucket to "catch", so its processing capacity has been greatly improved.

3. The higher energy utilization rate reduces the energy loss caused by the wheel bucket in the process of lifting, so that the energy can be better utilized.

4. High cleanliness. More time and times for the sand to be cleaned compared to wheel type sand washer.
