Because of the infrastructure of natural sand Used Impact Crusher Market resources growing in the field of many appear gradually reduce, even with no natural sand. Sand concrete sand is extremely short, and the quality from the demand is higher and greater. Especially high strength grade and the sum of the high performance concrete is really strict, in order to meet what’s needed of the fewer the amount of natural sand.

Artificial sand production can be divided into the rod mill crusher and sand making machine two categories. Sand has a rod mill process stable, mature features, but the volume and self-important , basic stupid big , complex maintenance , high labor intensity , and the big noise, big water , stone and more power , low yields. There are vertical impact crusher crusher crusher crusher , crushing and counter rotating disk Sand laminated form .

Vertical impact crusher ( sand making machine ) is smaller than the rod mill volume , basic simplicity , high efficiency , but the vertical impact crusher mechanism is not completely sand sand requires closed- loop circulation process large amount of the finished product sand fineness modulus larger , coarse particles , and the particle size distribution is not ideal, especially in the production of limestone sand grit and powder are more prone to the middle level of particles less than normal. This requires supplemented easy adjustment, stable quality rod mill to adjust. This can complement each other, that the impact of the joint use of vertical sand breaking technology combining with the rod mill , which is the ideal solution. In fact , finished by a vertical impact crusher sand is sand , crushed sand rod mill , the lower part of the screen material (≤ 3mm section ) blending together four parts of sand particles and powder products composed of more reasonable.
