Vertical grinding machines have advantages such as high grinding efficiency, low power consumption, large feed particle size, easy adjustment of product fineness, simple equipment process flow, small floor area, low noise, small dust, easy use and maintenance, low operating costs, and low consumption of wear-resistant materials.
Can be widely used in industries such as power, metallurgy, cement, chemical, non-metallic minerals, etc
It is mainly used for grinding raw cement, clinker, desulfurization limestone powder of power plant, slag powder, manganese ore, gypsum, coal, Baryte, Calcite, bauxite and other materials.
The vertical mill system consists of a host, feeder, classifier, blower, pipeline device, storage hopper, electric control system, collection system, etc. Design and manufacture a standardized modular pressure device. As the production capacity of the vertical mill increases, the number of grinding rollers of the vertical mill can be correspondingly increased. A motor driven reducer can be used to drive the grinding disc to rotate. The material moves around the grinding disc under centrifugal force and enters between the grinding rollers and the grinding disc. Under the pressure of the grinding rollers, the material is crushed due to compression, grinding, and shear forces, The ground powder is blown by the airflow of the blower to the classifier above the main machine for screening. Those particles that are too coarse still fall into the main machine for re grinding, while those that meet the specifications of fineness flow into the pulse dust collector with the wind. After collection, they are discharged through the powder outlet pipe to form the finished product. The purified airflow flows into the blower through the pipeline on the pulse collector and is discharged into the atmosphere.

Product advantages:
1. Large production capacity, low energy consumption, green and environmentally friendly.
2. The roller sleeve can be used upside down, which is beneficial for increasing the output of coal mills, reducing wear, and extending its service life.
3. Install explosion-proof devices to ensure safe production. The upper shell is equipped with an explosion-proof valve to prevent the explosion of coal powder in the mill and ensure the safe use of the equipment.
Structural features:
1. The foot shaped grinding disc and tire shaped roller sleeve used in the coal vertical mill are more suitable for coal powder grinding.
2. Grinding roller bearings do not require special sealing. The grinding roller device adopts a pair of self-aligning roller bearings, and the bearing sealing chamber extends to the outside of the machine casing, avoiding contact with dusty gases. Therefore, a simple sealing can ensure that the grinding roller bearings do not enter dust and do not require sealing the fan.
3. The transmission part of the mill does not require an auxiliary transmission device.
4. The slag removal part is simple. The coal vertical mill has less slag discharge, and the slag discharge port is equipped with a cover plate, so there is no need to install a slag discharge valve.
