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.
LUM Ultrafine Vertical Grinding Mill 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.
