Small Vertical Cement Grinding Mill Energy Saving Low Dust Pollution
Vertical Cement Grinding Mill produced by China ZK Corp is is a new type of high efficiency, energy conservation and environmental protection of grinding equipment, widely used in the grinding of raw cement, slag, cement clinker, raw coal and other raw materials. It gathers grinding, drying and powder selecting as a whole, with high grinding efficiency and high drying capacity ( the maximum material moisture can be up to 20% ). The vertical mill adopts dynamic powder selecting device, which comes with high powder-selecting efficiency and convenient adjustment of fineness.
China ZK Corp has provided various kinds of large and medium size complete sets of cement production equipments for more than 300 cement customers in domestic market. And engineering for equipment and technology, manufacturing, installation and commissioning as well as the supply of the spare parts and the training service can be offered by China ZK for customers.
Vertical Cement mill working process:
The material is grinded between rotor and ring as the rotor is rotating. The ground powder will be blown into the classifier; the fine powder will be collected by the collector while the coarse powder will be regrinded to the required size.
1. High grinding efficiency and low power consumption.
2. Low metal consumption in unit product.
3. Bed grinding with low noise.
4. Negative pressure and low dust pollution.
5. Small floor space, compact layout, system equipment with light weight and low investment for civil construction.

Working Principle of Vertical Roller 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.
