Sand washer is a kind of water washing style equipment to be matched with the sand making machine and can reduce the dust and stone powder which mixes with the final sand, so sand washing machine can improve the quality of the sand. So it is for us to usually divides sand washing machine into two types, including screw sand washer and bucket-wheel sand washing machine. Bucket-wheel sand washing machine performs well with its innovative leak-proof structure and reliable gearing, which enables the machine to cope with large amount of materials, lowers the power consumption, and improves comfort. Through triangular belt, reduction gears, and slow wheel gear, electrical motor drives impeller to slowly run, slipping gravels into wash trough and washing away impurities attached on the surface. At the same time the layer of moisture will be removed from gravels to make it possible for dehydration. Later, a power flow of water is formed by continuous water supplement, taking away with it the impurities. After finishing the washing, clean gravels will be brought by impeller to blow tank.
Compared with screw washer, failure rate in using bucket-wheel sand sand washing machine is largely reduced since the transmission part will be separated from water and sand. Mainly characterized by simple structure, stable running state, high efficiency, and high output, screw sand washer can be often seen in construction sites, power station, and concrete plant. Materials would vertically flow into the highly-rotary impeller, and with the help of high speed centrifugal force, all materials will be crashed in to pieces around the impeller. Again and again, after many times of crashing between the impeller and enclosure, materials will be discharged through pipes, forming a closed circuit and controlling and selecting the qualified products of standard particle size after many times of circulation. In this way, it can be well applicable in washing those fine and coarse materials, especially for sand used in building industry and road.cement mill Precio: belt conveyor: But what makes the screw sand washer salient is that it is equipped with adjustable weir plate, which plays a helpful role in ensuring the high efficiency, durability, and well effect in washing and dehydration. That accounts for the stability of fine products. In addition, the well ability in treatment and convenience of repair and maintenance are all characteristics shown on sand washer screw. We can easily see it in various ore extraction industries.
Working Principle of this machine: Feed material is normally delivered between two to four feet from the feed end of the box and is subjected to an aggressive washing action resulting from the intermeshing paddle design. The paddles perform two functions: they help convey material and are the catalyst material to material on scrubbing. The material clean works uphill, between the shafts, and is discharged out the bottom of the box. Deleterious materials are absorbed into water and carried over a weir on either side of the box. The length of the washer box is dependent upon the percentage and tenacity of clay or the waste to remove.
