LUM Ultrafine Vertical Mill

LUM Ultrafine Vertical Grinding Mill is independently designed by SBM on the basis of years of experience in grinding mill production. LUM grinding mill adopts the latest Taiwan grinding roller technology and German powder separating technology. The ultrafine vertical grinding mill integrating ultrafine powder grinding, grading and transporting has become a better choice in the ultrafine powder grinding industry.

Product Features: Higher capacity, better powder quality, more excellent comprehensive performances

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

  • Higher Yielding Rate, Better Quality

    In order to avoid materials’ long lingering time, repeated grinding, high iron content and other problems occurring during the grinding process of traditional grinding mills, SBM specially designed unique roller shell and lining plate grinding curve. This design is easier to generate material layer, and can realize high rate of finished products by once powder milling, which can greatly enhance the working efficiency of grinding mill and improve the whiteness and cleanliness of finished products.

  • Double Position-Limiting Technology Makes Operation More Stable

    In the LUM Ultrafine Vertical Grinding Mill, the contact point between roller shell and millstone liner plate adopts electronic limiting technology and mechanical limiting protection technology, which can avoid the destructive impact (e.g. the grinding roller directly smashing the millstone) caused by machine vibration (e.g. machine vibration caused by mine explosion) and guarantee the operation stability.

  • Reversible Structure Gets Maintenance Easier

    During the design process of LUM Ultrafine Vertical Grinding Mill, SBM fully considered the maintenance problems which may be caused by heavy grinding roller, and finally developed and designed the reversible structure. Through this structure and hydraulic adjustment system, the operator can easily and rapidly move the grinding roller out of the body for checking and replacing roller shell and liner plate, and carry out other maintenance operations, so as to reduce the shutdown losses.

Working Principle

Through spiral feeder, materials fall onto the center of grinding plate of LUM Ultrafine Vertical Grinding Mill. Driven by the motor of host, 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.
