Application of vertical powder grinding mill:
Vertical powder grinding mill is the equpment to produce fine and superfine powder of non-inflammable, non-explosive and brittle mineral, chemical and construction, such as calcite, carbon black,chalk, limestone, dolomite, kaolin, gypsum, and talc etc, totally more than 100 kinds of materials.

The structure of vertical powder grinding mill:
Vertical powder grinding mill is mainly composed of bucket elavator, hopper, main unit, cyclone powder collector, dust cleaner, muffler, blower, soud-proofroom and so on.

Working Principle of Vertical powder grinding mill:
When the grinding mill is at work, all the grinding rollers are rolling in the ring, and the materials are driven to the edge of the turnplate by the centrifugal force and fall down into the grinding chambers where the materials are repeatedly pressed, crushed and grinded by the rollers.
The high-pressure air blower constantly inhales air within the grinding mill and, in turn,  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, and clings to the surface of the filter bags. At the same time, the fine powders clinging to the surface fall down by the sudden vibration of the filter bags, which is caused by the instantly ejected high-pressure gas controlled by the pulse valve. The materials from the above two lots are sent by the conveyor at the bottom to get finished powders packed. In addition, filtered clean air will be emitted from the air outlet of muffler in the end.

Advantages of vertical powder grinding mill:
1. Ultrafine grinding 325-2500mesh(47-5um)
2. Fast delivery(20~30 days after deposit)
3. The grinding material moisture under 5%.
4. High capacity, 0.5-20 t/h.
5. Reliable and durable, long lifecycle of spare parts.
6. Firm, durable(steady use for more than 30 years) & easy to use
7.Convenient maintenance
