The Selection of Sand Making Machine for Closed Sand Production Line

In recent years, with the constant improvement of the requirements for sand production technology and environment protection, more and more stone factories, especially large-sized cement and building material groups that reform to enter the sand and stone sector, shift their focus on closed sand production.

Closed sand production refers to a production line in which all the machines are connected with belt conveyor and there is no loading machine. Adopting closed sand production line has two advantages: one is that it reduces the powder dust pollution, the other is that all the machines are connected with belt conveyor, so that loading machine is not necessary, which improves the efficiency of the sand production.

So, what kind of stone crushing and sand making machine should be chosen for closed sand production line? Here Henan Hongxing Mining Machinery Co., Ltd., who has rich experience in construction and manufacturing of closed sand production line and has profound research on multi-grading sand maker, highly recommend the selection of German original rotor centrifugal sand maker.

Rotor centrifugal sand maker is a high-performance sand making machine equipped with vertical shaft and it is mainly used for material crushing and cube reshaping. In its running process, every material particle sustains the external force, so that besides crushing, it has outstanding effect in stone and sand making aspect: first, it is able to improve the particle shape of the coarse aggregate; second, it is able to selectively crush the complex minerals.

In addition, rotor centrifugal sand maker is suitable for processing all kinds of materials with high hardness and high abradability, so that it is suitable for making sand with river cobble, granite and quartz. The double-cavity rotor of rotor centrifugal sand maker endows it with high sand making rate and low abrasion rate and easy changing and convenient maintenance of quick-wear spare parts, so that it is more economical and durable than impact type sand maker and vertical shaft sand maker.

In particular, in the closed sand production line, the adoption of single-stage jaw crusher and rotor centrifugal sand maker can change the multi-stage crushing into two-stage crushing, thus greatly saving the operation cost of the closed sand production line.
