Granite is uniform in structure, rigid in texture and beautiful in color. It is a kind of high-quality durable aggregate and considered the king of stones. Before making use of granite, we should crush granite into gravel and sand by using granite crusher.
The granite crushing production line is divided into three stages: coarse crushing, medium fine crushing and screening.
How to crush granite into gravel?
1. 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.
2. Medium and fine crushing
The coarsely crushed materials are screened by vibrating screen and then conveyed by belt conveyor to cone crusher for medium and fine crushing.
3. Screening
The medium and finely crushed stones are conveyed to the vibrating screen through a belt conveyor to separate stones of different specifications. The stones that meet the requirements of the customer's particle size are conveyed to the finished product pile through the belt conveyor. The impact crusher crushes again, forming a closed circuit cycle.

How to crush granite into sand?
The granite sand making process is divided into four stages: coarse crushing, medium fine crushing, sand making and screening.
1. 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.
2. 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.
3. 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.
4. 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.
