After crushing and screening, the artificial sand and the natural sand obtained by sand mining equipment, all must pass through the process of flushing, classification, dewatering, removing the dirt and impurities so that it can be used as aggregate in concrete, and usually using sand washing machine. Therefore, sand washing machine is widely used in metallurgy, construction, highway, anti-corrosion gravel field, mining, building materials, transportation, chemical industry, water conservancy and hydropower, concrete mixing station and other industries in the material washing.
2.Structure features:
Sand washing machine is composed of a gear, reducer, rack, sedimentation tank, impeller, belt wheel, motor and other important components. It is characterized by high degree of cleanness, reasonable structure, large capacity, low power consumption, less sand erosion, and the structure is simple, so maintenance is convenient.
3.Working principle:
When sand washing machine works, a motor through a triangular belt, reducer, gear reducer drives the impeller to rotate slowly. Sand and gravel are thrown into the washing trough through the feeding tank and rolling by the impeller , grinding with each other to remove impurities covered on gravel surface, while destroying the water vapour layer coated grit, in order to facilitate the dehydration.At the same time, add water, forming a strong flow, timely to wash impurities and the foreign body of low specific weight away, and that are discharged from the underflow outlet of washing tank, completing cleaning function. Clean gravels are carried away by the leaves and finally poured from rotation of the impeller into the discharge chute, which completes sand cleaning process.
