★ fine sand recycling device product introduction

At present, most existing artificial sand production lines adopt wet production processes. No matter which type of sand washing machine is used, the biggest drawback is that the fine sand (particles below 0.16 mm) is seriously lost, and some even lose more than 20%. This not only loses production, but also seriously affects the grading of sand, resulting in unreasonable grading and coarser modulus, which greatly reduces the product quality of machined sand, excessive fine sand discharge, and serious environmental impacts. Pollution.

★ Fine sand recycling device works

1, fine sand recycling system structure: by the motor, slurry pump, sediment separator, TY linear shaker, storage bins, return boxes and other components.

2. The working process of the fine sand recovery system: The pump transports the sand water mixture to the sediment separator, and the centrifugally grading concentrated fine sand is provided to the vibrating screen. After being dewatered by the vibrating screen, fine sand and water are effectively separated, a small amount of fine sand and mud. After returning to the material box and returning to the storage box, when the liquid level of the storage box is too high, it is discharged through the discharge port. The weight concentration of the material recovered by the linear vibration sieve is 70%-85%. Adjusting the fineness modulus can be achieved by changing the pump speed, changing the mortar concentration, adjusting the amount of overflow water, and replacing the nozzle to complete the three functions of cleaning, dewatering and grading.

★Advantages of fine sand recycling device

1. In the traditional artificial sand wet processing technology, the sand washing and dewatering of artificial sand use spiral sand washing machine, and the loss of artificial sand (especially fine sand) can hardly be controlled. The fine sand recovery device can effectively reduce the loss of fine sand and make it within 5%-10%. It solves the problem of high sand fineness and low stone content in the artificial aggregate processing system.

2, the use of polyurethane mesh screen shaker, polyurethane screen life than other types of screen longer, and difficult to plug the hole.

3, mud sand separator lined with polyurethane, to improve the life of the entire device, can successfully complete the slurry concentration, liquid clarification and other work.

4. The fine sand recycling system can recover 85% of the fine particles in the total discharge volume, which has unmatched technical and economic advantages.

5. Fine materials are fully recovered, which reduces the workload of cleaning the sedimentation tank and reduces the cost of the sedimentation tank cleaning.

6, according to the different requirements of users, design the corresponding solution.
