Large Heavy Calcium Limestone Grinding Equipment 6 - 80t/H

6-80t/h Limestone Powder Mill, Large Heavy Calcium Grinding Equipment, Vertical Mill Manufacturer

Description

Limestone is a common non-metallic mineral.

Advantages of HVM series vertical mill:

1. High efficiency and energy saving:
(1) The grinding efficiency is high and the energy consumption is low. Compared with the ball mill, the energy consumption is 40% - 50% lower;
(2) Large production capacity of single machine, which can make use of low valley power;
(3) Vertical mill technology and equipment are energetically advocated new technologies for energy conservation and consumption reduction, which are conducive to enhancing the competitiveness of enterprises in the powder industry in the region and even in the country;

2. Environmental protection
The vertical mill process system operates under negative pressure, and no dust escapes.

3. Grinding
The size of limestone fed to the mill is large, and the production capacity of a single mill is large, which can be used for large-scale production. The capacity of a vertical mill can reach that of multiple Raymond mills or ball mills.

4. High system operation rate
It integrates crushing, grinding, drying, powder selection and transportation, with simple process flow, fewer system failure points and fewer vulnerable parts of equipment.

5. Drop
Compared with the ball mill, the grinding mode of the vertical mill can save 30%~40% of the energy consumption and reduce the production cost.

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.

Technical Data

Re:The data based on Mohs'hardness 3-4 material

      Limestone Bond Index≤13kwh/t

Hefei Hengcheng can process but not limited to limestone, barite, calcite, heavy calcium carbonate, etc., and grind the system to make powder. The system is in a negative pressure state, without dust spillage, and the environment is clean. At present, it has been well verified in China, has established environmental protection and energy conservation for the grinding industry, and has become a manufacturer in this field.
