As we all know, the general production line of sand includes jaw crusher, impact crusher or cone crusher to crush the materials. The materials after crushing are transported by the belt conveyor to sand making machine for another further crushing. The product of sand making machine are screened by vibrating screen and the products which are more than 5mm have to return to the sand making machine, that we call it a closed circuit. The products which are less than 5mm are cleaned by a sand washer, and then transported to the final product stock.

In the process of sand washing, there is a problem. The sand lost easily with water especially the fine sand. As we all know, in order to obtain raw material locally, providing convenient water and material, the river sand making factory was always built near the river. After cleaning, the water pollutes the environment directly, also caused the waste of fine sand. In such a situation, the fine sand collecting machine is a very good solution for this problem.

The advantages of using a fine sand collecting machine are as follows:

1. It can effectively reduce the loss of fine sand, which can be controlled in 5 - 10%. It is a good solution for too much fine sand but less stone powder contented in the final products.

2. The polyurethane liner of the cyclone can improve the service life of the machine

3. The fine sand collecting machine can recycle maximum 85% of the fine particulate material.

4. The fine particles are fully recycled; so that to reduce the workload of the sedimentation tank and the cost of the settling tank.

5. The fine sand collecting machine can reduce the natural stacking time of fine material. The sand can be directly supply to the market.

Therefore, the fine sand collecting machine can effectively solve the loss of fine sand, but also can bring huge economic benefits to the manufacturer.
