Environmental Protection and Health One

LUM is of little dust and noise, achieving Environmental Protection Request, it is quite environmentally friendly

To Improve the Purity Two

Low investment cost: LUM use PLC/DCS automatic control system, well save the cost of operators.

High Efficiency Three

LUM has excellent grinding-efficiency for the special design of roller shell and grinding plate curve.

Low Cost Four

Utilize advanced working principle and reduce the grinding time, as a result, the final products has little iron and the whiteness and purity are raised.
