With the rapid development of the construction industry, sand and gravel aggregates are used in highways, railways, building construction, etc., and machine-made sand is widely used. Machine-made sand is made from sand making equipment, and the raw materials will contain a lot of impurities. So does the finished sand and gravel need to be washed? ? ?
the answer is
Uncertain! Everything depends on the situation.
The purpose of washing machine-made sand is to remove impurities and improve the quality of the finished product. Therefore, if the raw material contains high mud content and high stone powder content, and the finished product wants to meet the standards for construction sand, we need to wash the machine-made sand. On the contrary, we do not need to wash it!
So, if water washing is required, which sand washing equipment do we generally choose?
Considering that the specifications of the finished machine-made sand are relatively fine and contain a lot of stone powder, in order to better reduce the loss of sand, it is recommended that you use a wheel bucket sand washing machine. The wheel bucket sand washing machine is mainly composed of impellers, gears, It is composed of bracket, sedimentation tank, reducer, pulley, motor, etc. It adopts mature technology and has strong sealing performance and small sand loss.
During work, the wheel bucket rotation principle is used to tumble and grind each other driven by the impeller to remove impurities covering the surface of the sand and gravel, and at the same time destroy the water vapor layer covering the sand grains to facilitate dehydration; at the same time, water is added to form a strong water flow. Impurities and foreign matter with small specific gravity are taken away in time and discharged from the overflow outlet washing tank to complete the cleaning effect. The clean sand and gravel are taken away by the blades, and poured into the discharge trough from the rotating impeller to complete the cleaning function of the sand and gravel.
