stone crusher for sale

In the process of stone processing by stone factory, it is often accompanied by the production of fine particles and stone surface. These are called stone powder. Stone powder can be used instead of sand in concrete aggregate, but it needs to be screened and cleaned, that is to say, the content of stone powder must be controlled.

Infrastructure construction for sand aggregate demand is increasing, washed sand has been more widely used. Stone powder washed sand in many areas can replace river sand applied in concrete aggregate, can effectively reduce the cost, according to a reasonable proportion can be configured with high-performance concrete aggregate, in order to improve the taste of sand aggregate, improve the value of resource utilization, usually use sand washing equipment to recover the fine sand in stone powder, with sand washing equipment, the investment value of washed sand is higher and higher.

If the mud content of the stone powder raw material itself is relatively high, then the sand content will be lower, on the contrary, the less mud content of the stone powder, the higher the sand content will be. In general, a ton of stone powder can be washed out of 0.8-0.9 tons of sand, and the loss is mud and fine powder. Most of the stone powder below 0.2mm will be lost in the process of cleaning.

The impeller type sand washing equipment mainly realizes the cleaning of the stone powder through the constant turning of the impeller, the motor drives the triangle belt, the gear and the reducer, and then the gear drives the impeller to rotate, the sand and stone roll in the washing tank driven by the impeller, and grind each other, remove the impurities covering the surface of the sand and stone, the clean sand and stone are taken away by the blade, and then the sand and stone are poured into the discharge tank from the rotating impeller. To complete the cleaning function, because the sand, water and transmission device are set isolated, therefore, the failure rate of the machine is lower.
