 LM vertical roller mill

LM series vertical grinding mill is based on advanced home& abroad technology, combined with years of experience in the production of grinding mill. It is an ideal equipment that integrates crushing, drying, grinding and conveying all together. LM Vertical Mill is a new kind of large scale power mill which is designed specially to solve the problems of low capacity and high consumption of industry mills. With a decade of years’ research of mills, Vertical Roller Mill is designed and manufactured based on our advanced design idea, and in combination with the European technology and the market demand. It adopts reliable structure and reasonable process flow, integrated with drying ,milling, classifier , elevator. Especially ,it can fully meets the requirement of clients in the high production of powder and its main technical and economy indicator reaches the international level.

Technical advantages:

1)The time materials stayin the machine body is short ,which can reduce the repeating grinding and have a stable quality.

2)the adjustable dry air temoeture,and high drying ability ,energy-saving.

3)the non-direct contacting equipment installed on the roller shells and the grinding liner can avoid the damage compact and strong shaking.

4)the machine merges the crushing ,drying,grinding ,and classifying into a single whole .

5) the grinding roller and the liner adopts the high-quality materials ,which can reduce the abrasion and increase the service life .

6)the whole seal of the equipment makes the system work in a negative environment with no dust leaking and a clean environment.

Note: 1. Input material should be brittle material with Mohs hardness not more than seven.
2. Hot air is needed only when there is a requirement that water percentage of final product should be less than raw material.
3. If the material is hard to grind, motor power take large value.
