Good economic returns, low investment costs.
Device uses the principle of long separator, and each rotor frequency control are used, the fineness of grinding products can be completed within a selected range, you may not have a secondary sorting, without the presence of low-grade material, better economic ; and the device is equipped with an automatic control system, which enables remote control of such equipment operating in the production line is more simple, and the design of materials and equipment used in relatively high, the structure is strong, so that the frequency equipment damaged in the production line to reduce the number.
