LUM-Series Ultra fine vertical grinding mill is an advanced mill which combining our company’ several years of mill-producing experiences, It is designed and researched based on vertical mill technology, absorbing the worldwide ultrafine grinding theories. This series is a professional equipment including ultra fine grinding, classification and delivery.


New design, efficient crushing

Multiple frequency rotor classifier. The fineness of the finished product can be adjusted in the changeable scope. No need for the second wend-blowing classification and no existence of the low grade material.

Unique design, quality assurance

The percentage lower than 2 um in the finished product is as high as 70% , low residue when fineness is 325 mesh, also can get more finer size from the final product by second classification.

Technology upgrade, cost decreasing and benefit increasing

The ultra fine theory and the multiple classifier make it save 30%-50% energy than the other types of mills when producing products with the same fineness , so it is economic.

Efficient working, easy maintenance

PLC/DCS automatic control is used to increase the pressure for the rollers ,which makes the pressure can be controlled accurately and no need for the manual operation.
