1. Multiple functions, integrate sand washing, fines recycling, coarse and fines concentrated dehydration in one.

2. By connecting the two sand washers in series and the spray water pipes arranged around them, the material can be cleaner fully.

3. The fines recovery device can recover more than 90% of fines in the overflowing muddy water during sand washing, to make the finished sand grading well, and effectively improve the economic benefits.

4. If the muddy water treatment system is configured later, the pressure of concentrated filter press can be greatly reduced, so that the entire process can be optimized.

The material after pre-treatment enters first cleaning tank, under the constant rotation and stirring of impeller, material is full mixed into water, and the impurities on the surface of material are taken away by water to make material cleaner.

Then the impeller picks up material from the water and leaks water and impurities, and transfers the qualified material to the second tank and repeat the process in first tank, so the materials is further cleaned twice.

Then enter to dewatering screen, and remove a large amount of water through the vibration of dewatering sieve, so that the material is more convenient to store and transport. The material leaked in water tank enters slurry pump through overflow device, and is pumped to the hydrocyclone for concentration and recovery. After concentration, the qualified materials are returned to dewatering screen for dehydration. The excess muddy water and impurities enter the return tank.
