Why the fine sand need recycling?

The status of artificial sand washing at present, most of the existing artificial sand production lines are utilizing wet production process. No matter what the type of sand washing machine is, the biggest drawback is that the fine sand (particle diameter is between 0.045mm and 1.6mm) will be in a serious loss and sometimes the loss will be over 20%. This drawback will not only reduce the output, but also affect sand gradation. For this reason, the gradation is not reasonable and fineness modulus is larger so that the product quality of mechanism sand will be largely reduced.

Working principle of fine sand recycling machine:

1. Fine sand recycling machine structure: consists of electrical machine, slurry pump, hydro cyclone, ZKR line vibrating screen, purge tank and material returning bin, etc.

2.Working process of fine sand recycling device : the sand and water mixture is sent to hydro cyclone. After centrifugal grading enrichment, the fine sand is sent to vibrating screen by sand sinking mouth. After dehydration by vibrating screen, the fine sand is efficiently separated from water and a few of fine sand and clay come through material returning bin then come back to purge tank. When liquid surface in the purge tank is high, the discharge hole can adjust the liquid surface. The weight concentration of recycling materials in line vibrating screen is 70%-85%. Adjusting fineness modulus can be realized by changing pump rotation speed, changing pulp consistency, adjusting overflow water and changing sand sinking mouth. By the process above, the fine sand recovery system can finish three functions, cleaning, dehydration and grading.
