June.05,2018

LZZG sand washing machine is a compact multiple functions sand washing machine, which is based on wheel sand washer and fines recycling system. It is widely used for washing, screening, recycling and dewatering crushed sand, river sand, sea sand and other kind of sand.

Then there is a point must you all very concerned, how does the sand washing machine work?

Step1: Washing
The electric motor runs slowly with the impeller after decelerated by the belt, decelerator and gears wheel. The sand and stone flow into washing launder from feeding launder, rolls with the impeller, 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.
Step2: Dewatering
Qualified sand is shoveled to the dewatering screen directly. This dewatering screen sieve is made of PU polyurethane material, no blocking, can bear high temperature and corrosion resistance is high, service longer working hours. From this step, wet sand moisture can be highly reduced.
Step3: Recycling
Waste sand water is extracted by slurry pump into high pressure sediment separator, fine sand 0.074-3mm is sprayed onto polyurethane screen also for dewatering, the waste water is back to return box and flowing out.
