HJN Efficiency Powder Separator:Performance steadily, large throughput.Steep gradient of the grading through the special device.Adopt the new standard of cement, the degree of fineness and the specific surface area are early to be control.Rotor vane can enlarge the grading area,the capacity can be higher 15%.The rotation speed can be adjusted easily,,and the grading point can be chose expediently. So it is the same with various cement system.The finished product can lower in temperature with the cool air.The waste gas can be used frugally.Compact conformation,small volume , easy to lay.
