LUM Ultrafine Vertical Grinding Mill


Higher capacity, better powder quality, more excellent performances

Based on ZENITH’s abundant experience in producing vertical grinding mills and the latest technology from Taiwan &Germany, ZENTITH pushed out the LUM Ultrafine Vertical Grinding Mill, which gets high reputation from customers. It sets grinding, drying, classifying and transportation as a whole and takes little space. What’s most important is that it effectively reduces the investment cost.

Materials:Limestone, calcite, dolomite, petroleum coal, gypsum, barite, marble, talc, coal powder, etc.

Product Advantages


The LUM Grinding Mill uses unique roller shell and lining plate grinding curve. It‘s easier to generate material layer and can realize high rate of finished products by once powder milling.

The use of PLC control system and multi-head powder separating technology in this grinding mill can help control working status easily and reduce the energy consumption by 30-50%.

The electronic limiting technology and mechanical limiting protection technology can avoid the destructive impact caused by machine vibration and guarantee the stable operation.

The reversible structure and the hydraulic system allow operators to take the roller device out of the body for checks and to carry out maintenance more easily.

Working Principle of LUM Ultrafine Vertical Grinding Mill


Through spiral feeder, materials fall onto the center of grinding plate of LUM Ultrafine Vertical Grinding Mill. Driven by the host motor, the reducer rotates the grinding plate to form centrifugal force which forces materials to move towards the fringe of grinding plate. While passing through the grinding area between roller and grinding plate, bulky materials are broken directly by the pressure of roller while fine materials form a layer where materials crush each other. Broken materials after grinding continue moving to the edge of grinding plate until they are brought away by the airflow and enter the powder selector. Under the action of blades of selector, coarse particles which fail to meet standard of fineness drop to the grinding plate to have another grinding while powders meeting the standard enter the powder collector as finished products. For sundries like iron block in materials, when they move to the fringe of grinding plate, because of their heavier weight, they would drop to the lower cavity of grinding mill and next be sent into the discharging port by scarper installed at the bottom of grinding plate and finally be discharged out of the grinding mill.
