LUM Ultrafine Vertical Grinding Mill

LUM series ultrafine vertical mill is designed on the basic of years of mill production experience. It adopts the latest Taiwan grinding roller technology and German powder separating technology. The ultrafine vertical mill is a new kind of ultrafine grinding equipment that integrates ultrafine powder grinding, grading, collecting and transporting into one set.

Input Size: 0-10mm
Capacity: 5-18TPH
Material: Limestone, calcite, dolomite, petroleum coal, gypsum, barite, marble, talc, coal powder, etc.

Working Principle

The millstone is driven by motor of main unit through reducer, after the calculation of belt scale, raw materials, through elevator, spiral conveyer, star-shaped feeding valve and feed screw, fall on the center of plate from feed opening and they move to the edge of plate under centrifugal force, while passing through the grinding area between roller and plate, raw materials will be pulverized by the pressure of roller and the shearing force between roller and millstone.

Raw materials after grinding continue moving to the edge of millstone until they are brought into multi-rotor powder concentrator by the airflow at the edge of millstone from the high-pressure fan.

Oversize powder falls on the plate for re-grinding while the ones meet production requirements enter the dust filter along with airflow, and then transported to product bin by elevator or pneumatic transport syster.
