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.
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.
SBM adopted PLC control system and multi-head powder separating technology in this grinding mill, which completely solve two problems, i.e. “high-precision and accurate cutting powder diameter, and fast switch of different production demands”. Users can accurately control the grinding pressure, revolving speed and other equipment working parameters. Compared with common grinding mills, this grinding mill reduces the energy consumption by 30%-50%.
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.
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.
There are tens of lines of numerical controlling machine tools. Operations such as steel plates’ cutting, bending, planing, milling and paint spraying are all controlled numerically. The machining precision is high, especially for the core parts.
SBM, whose businesses cover production and sales, takes responsibility for every machine produced by ourselves. We can offer customers technical services about products and original spare parts to ensure the worry-free operation.

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.
