Sand and gravel classifier, screw sand washing machine with good quality
The screw 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.
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.
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.
Base on years' experience and technology, LSX screw 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.
LZZG spiral sand washing machine is mainly used for many sandstone industries such as: sandstone factory, building work site, hydroelectricity dam, glass manufacture, oil well development. The machine is specially designed for sandstone and quartz sand company to wash, separate, and classify and dehydrate.
1. Three functions: cleaning, dewatering and grading.2. Cleaning and upward conveying at the same time.
3. Low water consumption; durable.
4. Impellers use wear resisting plate or polyurethane material, reduce the running cost.
5. Designed according to low volume, low investment.
6. Capacity of screw sand washer is above 100t/H, effectively control the sand washing loss.
