Introduction of River Pebbles
Pebble, a kind of natural stone, is mainly from the pebble mountain which is raised from ancient riverbed because of the earth's crust movement millions of years ago. The formation of pebble undergoes continuous extrusion and friction of flood and running water. Pebble is usually smooth under action of wave and flowing water and buried under the earth surface with sand.
The river pebbles resource in China is abundant, the main chemical composition of gravel is silicon dioxide, secondly it is composed by small amount of iron oxide and trace elements such as manganese, copper, aluminum, magnesium and compound, it has natural stone features of hard quality, compression, wear-resistance and anticorrosion, it is an ideal material for building application. Currently gravel sand making production lines are continually built all over the country, which guarantee the supply of quality aggregate for national construction projects.

Basic Process of River Pebbles Sand Making Plant
The pebbles sand making process is divided into four stages: coarse crushing, medium fine crushing, sand making and sieving.
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.
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.
