What is a vertical raw mill used for?

Vertical raw material mill

Raw material vertical mills are used for grinding cement raw materials or cement clinker, as well as other industrial raw materials such as construction, chemical, and ceramics. They have a series of advantages such as small volume, light weight, less land occupation, low power consumption, and long service life of vulnerable parts. Therefore, they have been widely used in industrialized countries in recent years.

Specifications And Technical Parameters Of HVM Raw Vertical Mill

Performance characteristics of raw material vertical mill:

High grinding efficiency. Adopting advanced material layer grinding principle, the system saves 20-30% energy on electricity compared to ball mills. As the moisture content of raw materials increases, the energy-saving effect becomes more significant;

Large drying capacity. Kiln hot air exhaust gas can be used to dry materials, and raw materials with a moisture content of up to 15% can be dried and ground simultaneously;

Therefore, they have been widely used in industrialized countries in recent years.

The equipment occupies a small area and the process flow is simple. HRM vertical mill integrates fine crushing, drying, grinding, powder selection, and conveying, without the need for additional drying, powder selection, and lifting equipment. The workshop area only accounts for 70% of the ball milling system, and the space only accounts for 50-60% of it;

Low noise, low dust, and clean operating environment. The grinding roller and grinding disc do not come into direct contact during operation, and there is no metal impact. The noise is 20-25 decibels lower than that of a ball mill. The system adopts fully sealed negative pressure operation, without dust, and the production environment is clean;

Low wear and low product pollution. Metal wear is generally only 5-10g/t of the product, which has little metal pollution to the product;

The grinding roller sleeve can be used upside down, which is beneficial for extending its service life and reducing production costs. Convenient operation and maintenance;

The chemical composition of the grinding product is stable and the particle grading is uniform, which is conducive to calcination.

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, 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 picked up by the Jet stream at the wind ring at the edge of the grinding plate. Large particles fall directly onto the grinding plate for grinding again. When the materials in the airflow pass through the dynamic and static separator, under the action of the rotating rotor, the coarse powder falls onto the grinding plate for grinding again. The qualified fine powder is grinded together 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.
