How does the washing plant work?

1. Feeding the crushed sand into vibrating screen for classifying, big granular part are forming stockpiles through the belt conveyor.

2. Feeding the part under screen mesh into sand washer machine to wash the ≤75 micron clay silt and dust out, the overflow slurry will be pumped into the cyclone to recycle the fine sand. After recycling, the waste muddy water overflows to return box, then storaged in a transfer pond through a pipe.

3. The muddy water will be extracted by pump to S-6000 thickener from the transfer pond, Thickener is a machine based on gravity and sedimentation making solid-liquid separate from each other by using chemical flocculant. Suspended solids settle down into bottom, while purified water flows away from overflow opening on the top of tank into clean water tank.

4. Muddy water are extracted by slurry pump to filter press, our two sets G250㎡filter press will alternant dewater solids the muddy water and form mud cake, while clear water flows to clean water tank.

5. The whole sand washing plant muddy water recycle rate can reach above 90% and no pollutation dischange.


Final effects of washing plant process

1. Thoroughly cleaned and dewatered high quality finished products
Mud content < 3%
Water content of finished products is as low as 12%-15%.
0.074-3mm fines can be recycled by hydrocyclone.

2. Muddy water used during the process can be purified and recirculared by thickener and filter press

3. Solid waste dry discharge and dry piles
