Cement raw meal vertical mill is a high-efficiency, energy-saving, and widely-used new grinding equipment, which can be used in cement, electric power, chemical, non-metallic minerals and other industries. It has high efficiency, low power consumption, large drying capacity, and fine products. The advantages of easy adjustment, uniform particle size, easy control of chemical composition, low noise, low metal wear, less dust, simple system process, small footprint, and low investment have been widely used in foreign cement industries.

Product advantages

1. High grinding efficiency. Adopting the advanced material layer grinding principle, the power consumption of the system is 20-30% more energy-saving than the ball mill. As the moisture of the raw material increases, the power-saving effect is more significant;

2. Large drying capacity. The kiln hot air exhaust gas can be used to dry the materials, and the raw materials with up to 15% of the incoming water can be dried and ground at the same time;

3. The equipment occupies a small area and the process flow is simple. HRM vertical mill integrates fine crushing, drying, grinding, powder selection, and conveying. It does not require additional drying, powder selection, lifting and other equipment. The workshop area only occupies 70% of the ball mill system, and the space only occupies 50～ 60%;

4. Low noise, less dust, and clean operating environment. There is no direct contact between the grinding roller and the grinding disc during operation, no metal impact, and the noise is 20-25 decibels lower than that of the ball mill. The system adopts fully sealed negative pressure operation, no dust, and clean production environment;

5. Low abrasion, low metal pollution of the product, and metal abrasion is generally only 5-10g/t.

6. The roller sleeve of the grinding roller can be turned upside down, which helps to extend the service life and reduce the production cost. Convenient operation and maintenance;

7. The chemical composition of the grinding product is stable and the particle size is uniform, which is beneficial to calcination.
