River pebble sand making machine manufacturers/price

River pebble is a kind of pure natural stone. The main chemical composition of river pebble is silicon dioxide, followed by a small amount of iron oxide and trace elements and compounds such as manganese, copper, aluminum and magnesium.

Today, with the increasing shortage of natural sand, the artificial sand making machine for river pebbles has become a new trend. River pebble sand making machine is a new generation of sand making machine specially developed for river pebbles. River pebble sand making machine is designed by integrating the working principles and new technologies of various crushers. Its typical purpose is to adapt to the current artificial machine-made sand industry. It is an updated product of cone crusher, impact sand making machine and straight through sand making machine. After the optimized design of the deep cavity rotor of the machine, the material throughput is increased by about 30%, and the service life of the whole machine is increased by more than 40%, which greatly saves the cost and improves the efficiency. Process of river pebble sand production line: first, the coarse crusher preliminarily breaks the stone, and the coarse material produced is transported to the fine crusher by the belt conveyor for re crushing. The fine crushed stone enters the vibrating screen, which screens them into two kinds of stones. Those stones that meet the feeding granularity of the sand machine enter the machine-made sand, and the other part of the returned material enters the fine crusher, and part of the stones that enter the sand machine are made into sand, After being cleaned by the sand washer, the finished sand is made, and another part of the stones will be broken again by the sand washer.
