Due to the over exploitation of natural sand, the output of natural sand in the world is decreasing gradually. In the process of sand washing, whether the fine sand can be recovered or not has gradually attracted the attention of investors, so in the ranks of sand washing equipment, the common sand washing machine equipment has gradually been replaced by the sand washing recovery machine.
In the process of wet sand making, the finished fine sand whose diameter is less than 0.63mm after being cleaned by the sand washing machine is washed away by water flow, resulting in loss. It will not only bring some economic losses to the producers, but also cause serious pollution to the environment.
The fine sand recovery machine developed by LDHB production mainly transports the mixture of pump slurry sand and water to the mud sand separator. The fine sand concentrated by centrifugal classification is provided to the shale shaker through the sand settling nozzle. After dehydration by the shale shaker, the fine sand and water are effectively separated. A small amount of fine sand and mud are returned to the cleaning tank through the return tank. When the liquid level of the cleaning tank is too high, they are discharged through the discharge port. The weight concentration of recovered materials is 70% – 85%.
The adjustment of fineness modulus can be realized by changing the pump speed, changing the mortar concentration, adjusting the overflow water volume, and changing the mortar nozzle, so as to complete the three functions of cleaning, dehydration and grading, and make the recovery rate as high as 95%. The fine sand recovery machine can solve the problem of fine sand loss, control the loss rate of fine sand within 5-10%, effectively reduce the loss of production line and improve the production efficiency.
