Talcum Powder production Line recommended by Shanghai Zenith Mineral Co.,Ltd is LUM Series vertical roller mill:

Advantages of Shanghai Zenith LUM Series Vertical Roller Mill:

Roller and roller plate do not contact directly, the product whiteness is high;
The material is pressed and then intergranular grinding, good sphericity;
Hydraulic pressure, electronic limit, interlock protection mechanism;
National patent design, stable and effective bed, small vibration;
Special wear-resistant material.
Efficient multi-rotor powder classifier.
PLC frequency conversion control, powder fineness adjustable;
The particle size distribution is narrow and the content of 2μm is controllable
Ensure accurate cutting size and high reproducibility of products;
When producing products with the same fineness grade, it can save 30%-50% energy compared with ordinary mill
