LS
series screw sand washer is the professional sand washing machine
developed on the basis of previous technology and combined with the
actual situation of sand and gravel industry. It is a
high-efficiency sand washer which can separate the excess powder
and mud and so on in the raw material. When working, the sand will
grind each other under the driving of the impellers. By this way it
can not only remove the impurities wrapped on the surface of the
sand, nut also destroy the vapor layer wrapped around the sand, and
completes the impurity cleaning processing in powerful water
flow.
It is
suitable for washing, grading, impurity cleaning for metallurgy
industry, construction material, etc. It is the indispensable sand
washing equipment for housing construction, bridge construction,
highway and railway project, etc.
Features:
Three functions: cleaning, dewatering and grading.
2. Cleaning and upward
conveying at the same time.
3. Low water consumption;
durable.
4. Impellers use wear
resisting plate or polyurethane material, reduce the running
cost.
5. Designed according to
low volume, low investment.
6. Capacity of screw sand
washer is above **0t/H, effectively control the sand washing
loss.
Principle:
Screw
sand washer is developed according to the principle of different
particles with different fall velocities because of their sizes and
densities. Fine particles float in the water and form the overflow;
coarse particles fall down to the bottom of the trough and are
pushed to the top port by the impellers and discharge. During
working, the motor drives the impellers to rotate slowly by
triangle belt, decelerating motor and gears. Sand enters the
washing trough from the fed trough, roll and grind each other under
the driving of impellers. Then wrapped impurity around the sand
surface is removed and the vapor layer is destroyed at the same
time. While the impurities and dirt is removed by the added water
flow, cleaned material is conveyed upward by the rotating impellers
to the discharge chute.
