Parameter Table of Coal Vertical Mill

Performance advantages
*Efficient and energy-saving
When the fineness of the finished product and the power of the motor are the same, the output is more than twice that of the airflow mill, stirring mill, and ball mill.
*Long service life of vulnerable parts
The grinding roller and grinding ring are forged with special materials, greatly improving their utilization. Generally, it can last for more than one year. When processing calcium carbonate and calcite, the service life can reach 2-5 years.
*High safety and reliability
Due to the absence of rolling bearings and screws in the grinding chamber, there is no problem of bearings and their seals being easily damaged, and there is no problem of screws being prone to loosening and damaging the machine.
*Environmental protection and cleanliness
Using a pulse dust collector to capture dust and a silencer to reduce noise has the characteristics of environmental protection and cleanliness.
Structural composition
The HVM series ultra-fine vertical grinding machine is mainly composed of an electric motor, a reducer, a grinding wheel device, a grinding disc device, a pressure device, a powder selection machine, a feeding device, an oil station, a main engine, an electrical control system, and other parts.
1. Grinding wheel device: The main component of rolling materials, without power output, operates passively due to friction in contact with the material.
2. Grinding disc device: The grinding area of the material, connected to a reducer, rotates on its own.
3. Pressure device: Control the gap between the grinding wheel and the grinding disc to ensure the pressure of the grinding wheel during the grinding process.
4. Powder selection machine: With a multi head powder selection structure, it utilizes the principle of rotating centrifugal force to achieve fine powder screening and filtration in continuous production. It is an efficient and energy-saving powder selection device.

Vertical Mill operational principle
The main motor drives the grinding disc to rotate through a reducer, and at the same time, the airflow produced by the high-pressure fan enters the main machine from the air outlet. The material is fed into the vertical mill main machine by a feeding screw and falls into the center of the grinding disc. Under the action of the centrifuge, the material disperses from the center of the grinding disc to the surrounding areas. When passing through the roller passage area on the grinding disc, it is subjected to roller pressure, and large pieces of material are directly crushed. Small particles are then subjected to particle grinding after being compressed, which further crushes the material, Until it turns into powder. The powdered material continues to move towards the edge of the grinding disc until it is carried away by the strong airflow at the air inlet. When the material in the airflow passes through the upper powder selection machine, under the centrifugal force generated by the high-speed rotating impeller, the coarse particles re fall into the grinding disc. Qualified powder is collected by the dust collector after passing through the powder selection system with the airflow, which is the finished product.
