Serious environmental problems makes the sand and gravel resource are in great demand. Since the shortage of natural sand resources and more requirement on compressive strength, durability of concrete, high quality artificial sand is more widely used instead of natural sand for concrete production. Cement as binding material, gravel aggregates as ground mass, mixed with water by certain proportion, and by mixing, molding, we got raw materials with the feature of low cost, simple process, high compressive strength, durability. It is one of the leading civil engineering material.

Because of concrete that composed of cement, sand, gravel is widely applied, it increases the demand of gravel stone crusher . Shanghai Shunky Machinery Co.Ltd., 6s sand making machine is to cope with sand making. Combined with VSI sand making machine, Shunky developed a new generation sand making equipment, which has extraordinary effects in crushing limestone, pebbles, river pebbles, granite, perlite, sand tailings etc..

With the increasing awareness in environmental production, creating higher value is ?the new function of sand making machine.
