The Spiral Washer adopts inclination of 15°, under the water tub, three weir plates form the sediment pool, the screw head is immersed in this pool, the screw is driven by electric motor through reducer rotating continuously, the fresh water is feeding from porous plate at bottom of sediment pool, washed sand is discharged on the top side and delivered by belt conveyor.
Washing: The sand is feeding into the sediment pool from the feeding box, with the help of rotating screw blade, the sand is turning, rolling and grinding each other to eliminate impurity and water-air layer around sand to facilitate de-water. The fresh water rising current from the porous plate carries foreign matter to surface and overflow the weir plate, to finish washing processing.
Classifying: Material classifying is realized by overflowing the fine particle that does not meet the sandard requirements. The controlling method is adjusting height of overflowing weir and adjusting speed of screw.
Main Features of Spiral Washer :
1.Heavy duty, long service life and no quick-wear part
2.High washing, de-watering and classifying efficiency.
3.Economic and strong frame structure.
1) Reasonable structure, convenient maintenance, large processing capacity, small power consumption, high cleanliness.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) The processing capacity is large, because the spiral 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) Reduce the wear of some parts, spiral sand washing machine, do not need to increase the screen, so reduce the loss of the screen, prolong the life of the equipment.
5) The cleaning effect is better, spiral sand washing machine compared with wheel bucket type, the sand material after the turnover cleaning time and times more, better cleaning effect.
Base on years' experience and technology, Spiral sand washing machine is designed to provide bigger capacity and higher cleaning level than traditional ones. It is also called “stone washing machine” as its input materials size at most can be 30mm. Now it is widely used for cleaning materials in quarry, minerals, building materials, transportation, chemical industry, water conservancy and hydropower, cement mixture station and so on.
Spiral sand washer is a kind of efficient sand and gravel washing machine, which is widely used for sand and stone washing, gradation and impurities removing. Spiral sand washers are specifically to produce quality sand for construction, highways, railways, building materials, water and electricity industries and more.
Spiral sand washing machine can be divided into single spiral and double spiral washing machine, and with the features of power consumption, high cleanliness, good sealing structure, fully closed transmission device, adjustable weir plate ensure the durability of the product, good cleaning and dehydration effect, fine product stability and other characteristics.
