Special features of ultrafine mill, vertical cement mill

1. High efficiency, 0.5-12 t/h

2. Long lifecycle of spare parts. The ring and roller are forged by special material with high utilization.

3. High safety and reliability. As no rolling bearings or screws in grinding cavity, there are no problems caused by bolts shedding or rapid wear of bearings and seal components.

4. High fineness and flexible adjustment. 325-2500 meshes (47-5 microns) adjusted.

5. Environment-friendly. The application of pulse bag filter and muffler greatly alleviates dust pollution and noise.

6. Advanced intelligent speed control device. Convenient adjusting, more uniform particle size.

Working principle of ultrafine mill, vertical cement mill

After crushed by hammer crusher, the large materials become small ones and are sent to storage hopper by elevator, and then evenly sent to the upper distribution plate of the turn plate by vibrating feeder and sloping feeding pipe.

When the grinding mill is at work, the main bearing and each dial are driven by electromotor through reducer, and all the grinding rollers are rolling in the ring channels driving by dial through plunger. The materials are driven to the edge of the turn plate by the centrifugal force and fall down into the grinding chambers.

The high-pressure air blower constantly inhales air, the airflow with crushed materials are brought to the classifier whose high-speed impeller will screen the airflow: the unqualified particle size will fall and return to the mill for being reground while the qualified particle size mixed with air will go into the cyclone powder collector. Most of the qualified powders will fall and exit from the discharging valve at the bottom; a small proportion of the fine powders, with airflow, moves to the dust cleaner. The materials from the above two lots are sent by the conveyor to get finished powders packed. In addition, filtered clean air will be emitted from muffler in the end.
