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.
