Vertical Roller Mill Operation

Vertical Roller Mill Operation has a development trend in the large-scale, automation, energy efficient, easy to operate and maintain, prolong life, to expand the scope.Such as improving the mill classifier past is static, it is dynamic, changing inefficient to efficient;Outside material grinding cycle, that is, the material around the overflow when the disc is not entirely by the wind will take it to grind the top, but some of the larger particles of material through the chute, belt conveyor and elevator and other top to grind through after the election returns from the center top of the powder mill to the mill;Cement mill with a vertical roller mill.

Vertical Roller Mill Used In Limestone Grinding Line

Basic Info

Vertical Roller Mill Operation Capacity
Feed particle size: less than 10mm
Production capacity:5-18t/h
Suitable material: granite, marble, limestone, quartz stone, river pebbles, iron ore, copper ore

After being crushed into required sizes by the jaw crusher, the crushed limestone will be transferred to the hopper by the elevator and then being fed into the grinding cavity evenly and continuously by the vibrating feeder. The ground powder is flowed by the airflow of the fan and then graded by the classifier. The required vertical roller mill enter the collecting system through the duct, after separating and collecting and discharged from the outlet duct.

Because of the certain moisture of the raw material, while vertical roller mill working, the produced heat will lead to the gas evaporation and expansion which will change the quantity of the airflow. And each of the junctions of the ducts is not tightly sealed; the outside air will enter the grinding cavity which increases the circulating airflow. In order to keep the balance of the airflow and collect the extra gas into the dust collector, we need to adjust the gas event of between the fan and the main part. And then collect the powder which is brought by the extra gas. The extra gas will be discharged after being purified.
