Description
1.Introduction of sand washing machine：
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.
