The document discusses LSX Spiral Sand Washers. It has two models - single and double spiral. It washes sand and stone by grinding them together using an impeller while adding water to remove impurities. Clean sand is then lifted up and the water is removed and recycled as the sand moves through the machine. The technical parameters provided specify the capacity, power requirements, and dimensions of different LSX Spiral Sand Washer models.

1. LSX Spiral Sand Washer
LSX Series Spiral Sand Washer features at high capacity, high
cleaning, etc. There are two sorts for LSX Series Spiral Sand
Washer, that is: single spiral and double spiral, which can be widely
used in metallurgy, construction, water and electricity industry.

2. Operating principle of Sand Washing Machine:
The electric motor runs slowly with the impellor after decelerated by
the belt, decelerator and gears wheel. The sand and stone flow into
washing launder from feeding launder, rolls with the impellor, and
grinds each other. The impurity covering the sand is washing away.
At the same time, add more water, the strong water flow will take
away waste and some low-weight wastes from washing launder.
Through the above process, the washing function is finished. The
clean sand and stone is lift up by vane. When it goes up slowly, the
water begins to drop through the mesh and fall back in the washing
launder. On one hand, water is removed from the sand and stone;
on the other hand, the water can be fully used. Finally, the sand and
stone goes to the out launder from the rotary impellor to finish the
washing task. Characteristics of Sand Washing Machine: Reasonable
structure, Large capacity, Low consumption, Little loss of the sand
during the washing process, Low failure rate.
