The difference between the working principle of sand making machine and sand washing machine

01. Sand making machine use: The sand making machine is suitable for crushing and shaping of soft or medium-hard and extremely hard materials, and is widely used in various ores, cement, refractory materials, bauxite clinker, emery, glass raw materials, etc. In the field of engineering, it is an ideal production equipment for machine-made sand, cushion material, asphalt concrete and cement concrete aggregate.

The working principle of the sand making machine: the material falls into the feeding hopper, enters the high-speed rotating throwing wheel through the feeding hole, is rapidly accelerated in the throwing wheel, and its acceleration can reach dozens of times the acceleration of gravity, and then is ejected from the throwing wheel at high speed. First, it collides with another part of the material that falls freely after the rebound, and then hits the material lining (stone hits stone) or counterattack block (stone hits iron) together. The deflection moves downward, and collides with the material emitted from the impeller channel to form a continuous material curtain. In this way, a piece of material is subjected to two or more chances of impact, friction and grinding and crushing in the eddy current crushing chamber. The crushed material is discharged from the lower discharge port.

02. Use of sand washing machine: Sand washing machine is widely used in construction sites, sand and gravel plants, concrete dam construction sites of hydropower stations and other industries. It has high cleaning degree, reasonable structure, large processing capacity, low power consumption, washing There is little sand loss during the sanding process, especially the transmission parts of the sand washing machine are isolated from water and sand, so the failure rate is much lower than that of the commonly used sand washing machines at present, and it is a good choice for the upgrading of the domestic sand washing industry.

Working principle of sand washing machine: During operation, the motor drives the impeller to rotate slowly after deceleration through the V-belt, reducer and gear. The impurities on the stone surface will also destroy the water vapor layer covering the sand grains to facilitate dehydration; at the same time, add water to form a strong water flow, which will take away impurities and foreign objects with small specific gravity in time, and discharge them from the overflow washing tank to complete the cleaning effect. The clean sand and gravel are taken away by the blades, and the final sand and gravel are poured into the discharge chute from the rotating impeller to complete the cleaning of the sand and gravel.
