step 1. Feeding

The stone is blasted from the mountain and the large stone is sent to the vibrating feeder through the dump truck;

step 2. coarse crushed

The vibrating feeder sends the stone uniformly into the coarse and broken, and the coarse broken stone is first-stage crushed, and the stone material from the coarse broken material is transported to the fine broken through the belt conveyor for secondary crushing;

step 3. sand screening

The crushed material is conveyed by a belt conveyor to sand producing machine for fine crushing, and the finely crushed material is sieved by a circular vibrating screen for coarse sand, medium sand, fine sand and the like.

step 4. sand wash, fine sand recovery

For the sand powder containing strict requirements, a sand washing machine can be added behind the fine sand. The sewage discharged by the sand washing machine can be recovered by the fine sand recycling machine to reduce environmental pollution on the one hand and G sand production on the other hand.
