RM vertical mills are also commonly referred to as roller mills, medium speed mills, etc. in different industries. The models are characterized by crushing, grinding, drying and grading, and can be used for various types of moisture, properties and hardness. The pulverization of the material to the required particle size is ideal for the current milling industry.
The vertical mill is mainly composed of machine base, casing, column, separator (selector), reducer, grinding device (grinding disc and grinding roller), rocker arm device, hydraulic loading device, sealed pipeline system and slagging device. , operating platform and other components. The supporting equipments include thin oil lubrication station, hydraulic oil station, dry oil station, main motor and electrical control cabinet.
VRM type coal vertical mill technical parameters:
Application: used in pulverized coal injection, coal-fired boilers for power generation and heating boilers in the metallurgical industry, coal powder preparation in shaft kiln, coal chemical industry.
