There are different processes for artificial sand making. In places with abundant water sources, it is easy to use wet sand production line. In this process, the screw washing machine is an important device for washing out mud powder and stone powder mixed in sand.
With the rapid development of society, artificial sand has gradually become an indispensable product in many projects. In fact, the production of artificial sand is not simple, it needs to be broken through the jaw crusher, then broken through sand making machine. After the coarse sand is washed by the sand washing machine, the sand that meets the building use is obtained.
The surface of artificial sand is rough, multi-angled, so concrete with artificial sand is stronger than with natural sand. However, the artificial sand here refers to artificial sand that meets the building standards, not the artificial sand that has only been broken. Due to intense collision and stone itself has a certain amount of soil, so the artificial sand will contain a certain amount of stone powder and mud powder in processing. The presence of mud powder will seriously affect the quality of sand. In order to solve the problem of artificial sand with high powder, twin tub washing machine was launched by washing machine manufacturers. The mud powder in sand can be removed by sand screw wash plant, so that the artificial sand can reach the standard of construction sand.
The function of twin tub washing machine in sand production line is: when washing machine is working, the motor drives impeller to slowly rotate after being decelerated by V-belt, the speed reducer and the gear. At the same time, sand material feed into washing tank, which is driven by the impeller. Roll down and grind each other to remove impurities covering the surface of sand, and destroy the water vapor layer of coated sand to facilitate dehydration. At the same time, add water to form a strong water flow, and timely remove foreign matter with small foreign matter and small gravity. The washing tank is discharged to complete the cleaning operation.
