LM Vertical Roller Mill

Technical Features

Less Comprehensive Investment
Comprehensive Optimization
Lower Operating Costs
Greener & More Automated
Digitalized Processing

● LM Vertical Grinding Mill integrates crushing drying grinding separating and transport.

● The structure is simple while the layout is compact. Its occupational area is about 50% of that of the ball-milling system. The LM grinding mill can also be arranged outdoors which greatly reduces the investment cost.
● VANGUARD's LM Vertical Grinding Mill achieves lower energy consumption stronger drying capacity as well as lower abrasion and easier checks of core parts saving the operating costs greatly.
●The iron content in the product is very low and the iron generated due to mechanical wear is easy to be removed thus effectively guaranteeing the whiteness and purity of the material.
● The operation of LM grinding mill is stable and has small vibration so that the noise is small. The system is sealed in an integral manner and works under negative pressure so that there is no dust spilling and the environment can keep clean with the emission standard far better than the international standard. LM grinding mill is also equipped with expert-level automatic control system which can realize free switch between remote control and local control. The operations are simple and labor-saving.
