325 Mesh 6-80 t/h Limestone Vertical Mill , Power Plant Desulfurization Grinding Production Line
Description
The vertical mill is a grinding equipment integrating fine crushing, drying, grinding, powder selection and transportation. It is widely used for grinding and superfine crushing of various solid materials in cement, building materials, power, metallurgy, chemical industry, non-metallic minerals and other industries.
Working principle
the motor drives the grinding plate to rotate through the reducer, the material falls in the center of the grinding plate from the feed port, and the hot air enters the mill from the air inlet. Under the action of centrifugal force, materials move towards the edge of the grinding plate. When passing through the circular groove on the grinding plate, they are crushed by the grinding roller. The crushed materials are carried away at the edge of the grinding plate by the high-speed airflow at the wind ring. Large particles directly fall onto the grinding plate for re grinding. When the materials in the airflow pass through the dynamic and static separators, under the action of the rotating rotor, the coarse powder falls onto the grinding plate for re grinding. The qualified fine powder is grinded together with the airflow, The product is collected in the powder collecting device. Materials containing water are dried in the process of contacting with hot gas to reach the required product moisture.

Selection of vertical mill
The selection of vertical mill should consider many factors such as production line scale, material performance, grinding power consumption, etc.
Production line scale
In principle, vertical mills are suitable for large-scale production lines. Vertical mills integrate drying and grinding, and are characterized by low consumption and high yield. Therefore, vertical mills of different specifications or manufacturers can be selected according to different production scales, but comprehensive price performance ratio must be considered.
Properties of grinding materials
The selection of vertical mill is affected by material properties in two aspects: first, grindability, that is, how much force is required and how much work is consumed; The second is how much wear and tear materials cause to the equipment in the grinding process. As various vertical mills have different forms, the power consumption and wear of the same raw material on different mills will be different. The power consumption and wear of different materials on the same vertical mill must be determined through tests.
Main features of the product
1. High efficiency and energy saving:
The grinding efficiency is high and the energy consumption is low. Compared with the ball mill, the energy consumption is 40% - 50% lower;
2. Easy maintenance and low operation cost:
3. Low comprehensive investment cost:
It integrates crushing, drying, grinding and transportation. The process is simple, the system equipment is few, the structure layout is compact, and the floor area is only 50% of that of the ball mill. It can be arranged in the open air, and the construction cost is low, which directly reduces the enterprise investment cost.
4. Stable product quality:
5. High reliability
6. Environmental protection:
The whole system of HVM vertical mill has low vibration and noise;
Scope of application
1. In the cement industry, it is suitable for grinding cement raw meal, coal powder and cement clinker.
2. In building materials and metallurgy industry, it is suitable for grinding high fine slag powder and high fine steel slag powder.
3. In thermal power plants, it is suitable for the preparation of coal powder and limestone powder, a desulfurizer.
4. In metallurgical, chemical and mining industries, it is suitable for grinding various ores and other industrial solid materials.
