CLUM series ultrafine vertical roller mill is independently designed by SBM on the basis of years of experience in grinding mill production.
CLUM series ultrafine vertical roller mil 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.
1. 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 a 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.
2. More Energy-Saving Multi-Head Powder Separating Technology
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%.
3. Double Position-Limiting Technology Makes Operation More Stable
In the CLUM series ultrafine vertical roller 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.
4. Reversible Structure Gets Maintenance Easier
During the design process of CLUM series ultrafine vertical roller 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.
5. Digitalized Processing, Higher Precision
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.
6. Sufficient Supply Of Spare Parts, Worry-Free Operation
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.
The materials are fed onto the center of the grinding plate of the CLUM series ultrafine vertical roller mill through a spiral feeder.
The motor of the mill’s host drives the reducer, which rotates the grinding plate. This rotation creates centrifugal force, causing the materials to move towards the fringe of the grinding plate. As the materials pass through the grinding area between the roller and the grinding plate, bulky materials are directly broken by the pressure of the roller. Fine materials form a layer where they crush each other.
3. Airflow and Powder Selection
After grinding, the broken materials continue to move towards the edge of the grinding plate. They are carried away by the airflow and enter the powder selector. Within the powder selector, blades separate the coarse particles that fail to meet the desired fineness standards. These coarse particles drop back to the grinding plate for further grinding. The powders that meet the fineness requirements enter the powder collector as finished products.
4. Removal of Sundries
If there are any impurities like iron blocks in the materials, as they move towards the fringe of the grinding plate, their heavier weight causes them to drop to the lower cavity of the grinding mill. A scarper installed at the bottom of the grinding plate removes these impurities and sends them into the discharging port. Finally, the impurities are discharged out of the grinding mill.
The CLUM series ultrafine vertical roller mill combines grinding, centrifugal force, and airflow to achieve the desired fineness of the final product. It is designed to produce ultrafine powders efficiently and is commonly used in industries such as mining, metallurgy, cement, and chemicals.
