1, Introduction to Vertical Dolomite Mill

HVM vertical roller mill
Single machine introduction: HVM vertical roller mill is a product with independent intellectual property rights launched by Hefei Hengcheng, which actively draws on successful experience at home and abroad, and through continuous technological innovation and upgrading of the R&D team. The equipment is widely used in industries such as cement, electricity, metallurgy, and chemical industry, and is specialized in the three major fields of non-metallic ore, coal powder, and slag.

Application scope: Suitable for material grinding in industries such as cement, electricity, metallurgy, chemical engineering, and non-metallic minerals, with a focus on the three major fields of non-metallic minerals, coal powder, and slag
Processing materials: cement, coal, feldspar, calcite, talc iron ore, copper ore, phosphate rock, graphite, quartz, slag
Feed particle size: 38-65mm

Capacity: 13-70T/H

2,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.

3,Outstanding advantages of vertical mill

--- Low investment costs
Due to the integration of crushing, drying, grinding, and grading transportation, the system is simple, compact in layout, occupies a small area, and can be arranged outdoors, thus greatly reducing investment costs.
--- Low operating costs
High efficiency: The grinding roller directly crushes and crushes the material on the grinding plate, resulting in low energy consumption and energy savings compared to ball milling systems. Less wear: During work, the grinding roller does not come into direct contact with the grinding disc, and the grinding roller and lining plate are made of good materials, resulting in long service life and less wear.
--- High drying efficiency
The hot air that enters the mill from the outside directly and repeatedly comes into full contact with powdered materials inside the mill, with strong drying ability. It can save one dryer and energy for the mill system. By adjusting the temperature of the hot air, it can meet the requirements of materials with different humidity.
--- Environmental cleaning
Low vibration, low noise, and overall sealing of the equipment. The system operates under negative pressure, without dust leakage, and the environment is clean, meeting national environmental requirements.
