Important wear-resistant components such as vertical grinding rollers, grinding discs, and lining plates require good wear resistance. However, if the correct operating method is not mastered during the operation process, it is easy to cause damage to these wear-resistant parts, thereby reducing the operating efficiency of the equipment and increasing the maintenance cost of the equipment. In order to extend the service life of vertical grinding rollers, grinding discs, and lining plates, we can start from the following six aspects:
One is to choose suitable materials. Different materials have varying degrees of wear on the opposing grinding rollers, grinding discs, and lining plates. Materials with high impurities and hardness have a significant impact on the wear of wear-resistant parts. For example, as the content of quartz and pyrite increases, the wear of wear-resistant spare parts also increases significantly. Therefore, it is necessary to choose suitable materials.
The second is to ensure uniform feeding. According to the appropriate selection of raw material hardness and particle size, generally, harder materials with a diameter of less than 3 centimeters are more ideal.
Thirdly, it is strictly prohibited to put metal blocks into the vertical grinder. If necessary, an iron remover can be installed before the raw materials enter the mill to prevent metal substances from falling into the vertical mill and damaging related spare parts.
The fourth is to replace vulnerable parts in a timely manner. During maintenance and repair, the movable casing can be opened to promptly replace vulnerable parts; Before driving, the spindle must be turned to check for any abnormal sounds inside the machine. If any problems are found, they should be dealt with in a timely manner and the equipment should not be allowed to operate with defects.
The fifth is to maintain and inspect the rolling bearings inside the roller sleeve. Especially when replacing the grinding roller, it is necessary to clean the rolling bearings inside the roller sleeve and replace damaged parts in a timely manner.
The sixth is to effectively execute the correct startup sequence. Start the fan first and then the main engine, and stop the main engine first and then the fan when shutting down.
