The granite sand making process is divided into four stages: coarse
crushing, medium fine crushing, sand making and screening.
The first stage: coarse crushing
The granite stone blasted from the mountain is fed uniformly by the
vibrating feeder through the silo and transported to the jaw
crusher for coarse crushing.
The second stage: medium fine crushing
The coarsely crushed materials are screened by vibrating screen and
then conveyed by belt conveyor to cone crusher for medium crushing.
The crushed stones are conveyed to the vibrating screen through a
belt conveyor to sieve out different specifications of stones. The
stones that meet the requirements of the customer's particle size
are conveyed to the finished product pile through the belt
conveyor. The cone crusher crushes again, forming a closed circuit
cycle.
The third stage: sand making
The crushed material is larger than the size of the two-layer
screen, and the stone is conveyed to the sand maker machine through
the belt conveyor for fine crushing and shaping.
The fourth stage: screening
The finely crushed and reshaped materials are screened by vibrating
screen for coarse sand, medium sand and fine sand.
Note: For the sand powder with strict requirements, a sand washing
machine can be added behind the fine sand. The waste water
discharged from the sand washing machine can be recovered by the
fine sand recycling device. On the one hand, it can reduce
environmental pollution, and on the other hand, it can increase
sand production.
