In the rolling system, the material through roller press strong extrusion will produce a large number of qualified fine powder, into the grinding fineness can reach 0.08 material 50 ~ 70%, after V classifier classification are divided by a cyclone tube collection directly feeding ball mill, will form in the ball mill grinding, mat, reduce a storehouse grinding efficiency, therefore, qualified fine powder into the finished product is chosen, this part will increase the output of the system at the same time improve the ball mill grinding ability, improve the working condition of grinding machine.

System features:

Roller press and ball mill adopts parallel grinding process, the two devices have finished product produce, roller press is contained in the discharge of 10 ~ 15% qualified fine powder can be timely classifier, reduce the material of the ball mill a storehouse, reduce a warehouse material mat, improve the efficiency of grinding, "V" sorting out the coarse powder into the roller press again will be squeezed, through "V" fine powder into subsequent jeddah classifier for precise classification: sorting out the finished powder and coarse powder, coarse powder into the ball mill for grinding a storehouse, the final product cyclone tube after collection by conveying equipment into the shipping department.

In the roller pressing system, a jedda eddy current separator can be used to select the qualified finished powder produced by the roller presser, which can reduce the load of the ball mill while increasing the output of the system, reduce the phenomenon of overgrinding and improve the grinding efficiency of the ball mill system. The system has the advantages of high output, large output increase, high operation rate and low power consumption.
