High Efficiency Desulfurized Gypsum Grinding Mill For 150 - 2500 Mesh

What is the grinding process of a vertical mill?
The grinding process of a vertical mill is completed by a set of grinding devices (i.e. rollers and discs), where the material is ground into powder between the rollers and discs. The movement of the grinding device is driven by the rotation of the grinding disc and the corresponding driving of the grinding roller transmission. In addition to the self weight of the grinding roller, the grinding pressure mainly relies on a set of hydraulic devices to pressurize the material of the grinding disc. After grinding, there is a large amount of coarse powder in the material. After being selected by the matching powder selection machine, the powder selection process is through airflow sorting. During the airflow process, most of the coarse powder automatically falls onto the grinding plate and is received for re grinding. The rest is selected as finished products by the powder selection machine and sent to the finished product storage warehouse through the dust collection and transportation system.

HVM vertical grinding machine is an advanced grinding equipment designed and developed through extensive absorption of advanced technology from various vertical grinding machines both domestically and internationally, as well as drawing on a large amount of engineering application experience. It is safe, environmentally friendly, energy-saving, and efficient, and integrates drying, grinding, powder selection, and conveying functions. The main performance and economic and technical indicators of the equipment have reached the international advanced level.

Working principle: The electric motor drives the grinding disc to rotate through a reducer, and the material falls into the center of the grinding disc from the feeding port. At the same time, hot air enters the grinding chamber from the air inlet. Under the action of centrifugal force, the material moves towards the edge of the grinding disc and is crushed by the grinding roller when passing through the circular groove on the grinding disc. The crushed material is carried up by the high-speed airflow at the edge of the grinding disc, and large particles directly fall onto the grinding disc for re grinding. When the material in the airflow passes through the dynamic and static separator, under the action of the rotating rotor, the coarse powder falls onto the grinding disc for re grinding, and qualified fine powder is discharged with the airflow, Collect in the powder collection device, which is the product. Materials containing moisture are dried during contact with hot gases to achieve the required product moisture.

Specifications And Technical Parameters Of HVM Gypsum Vertical Mill

Advantages of vertical mill:
1. Reliable performance
The new grinding roller sealing device has more reliable sealing performance, and the grinding roller limit device effectively ensures the severe movement caused by material breakage.
2. Single machine production capacity is large, energy consumption is more economical, and compared to ball mills, energy consumption is 40-50% lower.
3. Clean and environmentally friendly
The entire system has low vibration, low noise, overall sealing, and full negative pressure operation, which is a new energy-saving and consumption reducing technology.
4. Automated operations
PLC fully automatic control system, remote control, and easier operation.
5. Excellent quality of finished products
The finished product has good particle morphology, narrow particle size distribution, good fluidity, high whiteness and purity, which can enhance the competitiveness of the powder market.
6. Low civil engineering costs
The complete system has fewer equipment, a compact structural layout, and a small footprint. Compared to ball mills, it saves 50% and can be arranged outdoors, resulting in low civil engineering costs.
7. Easy to maintain
The grinding roller can be turned out of the machine using a hydraulic device, and there is a lot of space for replacing the roller sleeve liner and repairing the mill. The grinding roller and grinding disc liner are made of special materials, and the service life of the entire machine is longer.
