BASIC PROCESS OF LIMESTONE SAND MAKING PLANT

The Limestone sand making process is divided into four stages: coarse crushing, medium fine crushing, sand making and screening.

The first stage: coarse crushing

The pebbles 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 broken

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 circular vibrating screen for coarse sand, medium sand and fine sand.
