High-efficient Sand Washing Machine—-Impurity The Sand


LZZG was born with the aim to develop new technologies in the field of quarries. The company’s activity is run by a staff of engineers and experts with a thirty-year experience in industrial and mining sectors for aggregates treatment production and specialized in ecological plants. LZZG is able to plan and supply aggregates crushing, screening, recycling and stockpiling plants and machines, water and sludge treatment plants and dust suppression systems included Technological innovation and simplicity of application to bring you quality and value for money: for LZZG value for money means advantages for the users and respect for society. The challenge of the present is indissolubly tied to the bet on the future.


The LZ Series High-efficient Sand Washing Machine is an equipment to wash sand in coordination with the sand making machine., which is used for washing away the stone powder and impurity in the sand made by the Sand Making Machine, to increase the sand quality. This machine is widely used in washing, grading and dehydrating quartz sand in Sand stone factories, Construction site, Glass Factory and so on.



  1. The machine is with high efficiency, reasonable structure, high capacity, low consumption and easy maintenance.
  2.  Drive Bearing device is separated from water and materials, which is greatly to avoid the bearing damaged due to soaking, touching sand and other pollutants.
  3. Compared with the spiral sand washing machine, the loss of medium and fine sand as well as powder is minimal, so the grade and fineness modulus of washed building sand can meet the required standard.

Working Principle

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.
