Screw type sand washing machine is an important equipment to complete glass grade silica and natural sand washing operation, which is divided into single spiral sand washing machine and double spiral sand washing machine. It can wash away the trace stone powder and impurities in the mixed sand produced by the sand making mechanism and improve the quality of the sand. Working process of glass grade silica sand washing machine.
LDHB 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.
In fact, there is no fixed answer to this question, because according to different situations, the configuration scheme and equipment model are different, so the price will be affected differently. However, generally, the price is about $30,000-$100,000. There are so many sand washer manufacturers in the market, with different scale, material use and equipment quality, So there is a slight difference in the price of the whole set.
