Professional Energy Efficient Vertical Roller Grinding Mill Prices For Vertical Coal Mill Plant
Product Introduction
HVM vertical roller mill is an energy-saving grinding equipment that combines mature vertical grinding technology, successful foreign experience, and our company's technological innovation and upgrading. It integrates crushing, drying, grinding, grading, and conveying, and can be widely used in industries such as cement, electricity, metallurgy, chemical, and non-metallic minerals. It focuses on three major fields: non-metallic minerals, coal powder, and slag.
Scope of application: sand and gravel yard, concrete mixing plant, dry mortar, power plant desulfurization, quartz sand, etc.
Materials: river pebble, granite, basalt, quartz, iron ore, diabase, limestone, calcite, dolomite, barite, talc, gypsum, bentonite, etc
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 water are dried in the Contact process with hot gas to meet the required product moisture.

Advantage
Low operating cost:
The grinding roller directly crushes and crushes the material on the grinding disc, which has low energy consumption and saves 40% to 50% energy compared to the ball milling system.
Less wear: The grinding roller does not come into direct contact with the grinding disc during work, and the grinding roller and lining plate are made of high-quality materials, resulting in long service life and less wear.
Stable product quality
(1) Due to the short residence time of materials in the mill, it is easy to detect and control product particle size and chemical composition, reduce repeated grinding, and stabilize product quality.
(2) The iron content in the product is very low, and the mechanical wear iron contained is easy to remove. When used for grinding white or transparent materials, the whiteness and cleanliness of the product are high.
Low investment costs
Due to the integration of crushing, drying, grinding, and grading transportation, the system is simple and compact, covering an area of about 50% of the ball milling system, and can be arranged outdoors, which can greatly reduce investment costs.
Dry
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.
Easy to operate and maintain
(1) Equipped with an automatic control system, it can achieve remote control and is easy to operate.
(2) Equipped with a limit device to prevent direct contact between the roller sleeve and the grinding disc liner, it avoids destructive impact and severe vibration.
(3) By repairing the oil cylinder, flipping the boom, replacing the roller sleeve and lining plate, it is convenient and quick to reduce downtime losses.
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 environmental requirements.
