The motor of vertical mill drives the grinding disc to rotate through the reducer. At the same time, hot air enters the vertical mill from the air inlet. The material falls into the center of the grinding disc from the discharge port. Due to the centrifugal force, the material moves from the center of the grinding disc to the edge of the grinding disc. When passing through the annular groove on the grinding disc, it is crushed by the grinding roller. The crushed material continues to move to the edge of the grinding disc until it is carried away by the airflow at the wind ring, and the large particles fall onto the grinding disc and continue to be crushed.
When the material in the airflow passes through the upper separator, under the action of the guide blades, the coarse material falls from the cone bucket to the grinding disc, and the fine powder is discharged from the mill together with the airflow and collected by the dust collector of the system. The collected powder is the product of the vertical mill. The material is dried in the process of contacting with the gas in the shell to achieve the required dryness and humidity of the product. By adjusting the angle of the separator guide blade (small vertical mill cannot be adjusted) and the speed of the separator rotor, the required coarseness and fineness of the product can be achieved.
The vertical mill roller is the core part of the mill, which requires sufficient toughness and good wear resistance. During the use of the vertical mill roller body and the wear-resistant lining, once there is a matching gap, the wear between the body and the lining will be aggravated. In addition, the hot air and cement particles will continuously scour the matching surface, resulting in the formation of grooves, causing impact and collision between the body and the lining. In severe cases, the lining will crack or even break, and the machine will be damaged, especially the damage to the reducer, causing a vicious incident. Once such a problem occurs, it is difficult to solve it with general repair methods, and the replacement cost is high. Zhili New Materials is a company specializing in mill accessories and rollers. It has rich experience and has produced many wear-resistant solutions for roller production. The service life of our rollers is 3 times that of other companies, which has been widely verified in the industry. The surface of our rollers can be surfacing, studs can be added, and ceramics can be added to improve the wear resistance of the product.
Regularly perform surfacing, oil change and other maintenance operations on the cement vertical mill to reduce the possibility of equipment failure and avoid affecting the normal production of the project. Especially for complex machinery and equipment, any problem with any component may cause the equipment to fail and fail to operate normally. How to improve the performance of vertical mills is a difficult problem faced by all companies. We can provide companies with wear-resistant solutions. If you are interested, please contact us.
