Vertical Milling Machine For Grinding Cement Raw Materials Clinker Coal Powder Slag

Vertical mill is a grinding equipment widely used in industries such as power, metallurgy, cement, chemical, non-metallic minerals, etc.

It is mainly used for grinding and processing materials such as cement raw materials, clinker, power plant desulfurization lime powder, slag powder, manganese ore, gypsum, coal, barite, calcite, etc.

Structural characteristics

It mainly consists of grinding disc, grinding roller, powder selector, pressure device, transmission device, housing and other parts.

Grinding disc: carries materials and carries out grinding process on them.

Grinding roller: Roll and grind the material on the grinding disc.

Powder selector: used to separate qualified fine powder and coarse powder to ensure product fineness.

Pressure device: provides grinding pressure for the grinding roller.

Transmission device: Drive the grinding disc to rotate.

Working principle

The material enters the center of the grinding disc from the feeding port and moves towards the edge of the grinding disc under the action of centrifugal force. At the same time, the grinding roller crushes and grinds the material under the action of the pressure device. The ground material is brought into the powder selection machine by high-speed airflow, and qualified fine powder is collected as finished products, while coarse powder is returned to the grinding disc for regrinding.

Advantage

High grinding efficiency: Adopting the principle of material layer grinding, the energy utilization rate is high.

Small footprint: With a compact structure, it occupies a smaller area compared to traditional ball mills.

Strong drying ability: can use hot air to simultaneously dry materials.

Easy to operate: high degree of automation, stable and reliable operation.

Energy saving and environmental protection: low energy consumption, low noise, and can reduce dust emissions.

Application area

Widely used for grinding cement raw materials, clinker, coal powder, slag and other materials. In modern industrial production, vertical mills have become one of the important grinding equipment.

Model and main parameters

 HLM type ultrafine vertical mill

MLK type slag vertical mill

LM series vertical mill

LM-1300: Suitable for grinding various materials, with certain processing capacity and grinding efficiency, specific parameters vary from manufacturer to manufacturer.

LM-1700: It belongs to a larger model of vertical mill with strong processing capacity, which can meet the needs of large-scale production.

LUM series ultra-fine vertical mill

LUM15-3X: Excellent in fineness control, suitable for production scenarios with extremely high requirements for powder fineness. The output depends on specific materials and production requirements.

LUM16-3X: Similar to LUM15-3X, it has good ultrafine grinding ability, but the parameters may differ in terms of output, motor power, etc.

JM series vertical mill

JM400: With a small production capacity of 5-150 tons per day, it is suitable for small-scale or experimental production.

JM1500: Compared to JM400, the grinding disc has a larger diameter and stronger production capacity, which can meet the needs of large-scale production.
