Vertical impact crusher is a crushing equipment widely used in mining, construction, chemical and other industries, with characteristics such as high crushing ratio, high crushing efficiency, and stable operation. This article will provide a detailed introduction to the working principle and maintenance of a vertical impact crusher to ensure its normal operation and extend its service life.



1、 Working principle of vertical impact crusher

The vertical impact crusher mainly consists of an electric motor, a reducer, a hammer head, a counterattack plate, a sieve plate, a base, and other parts. Its working principle is that the electric motor drives the rotor to rotate through a reducer. The hammer on the rotor rotates at high speed under the action of centrifugal force and is thrown towards the impact plate, impacting the material on the impact plate into small pieces or powder. During the impact crushing process, the material is subjected to repeated impacts and collisions from the hammer and impact plate, gradually reducing its particle size until it reaches the required particle size.

The working principle of a vertical impact crusher is mainly based on the principle of impact crushing, which causes the material to fracture and break through the impact and collision between the high-speed rotating hammer and the impact plate. Meanwhile, due to the design of the shape and angle of the hammer head and impact plate, the particle size of the crushed material is uniform, improving the crushing efficiency.

2、 Maintenance and upkeep of vertical impact crusher

In order to ensure the normal operation and extend the service life of the vertical impact crusher, regular maintenance and repair must be carried out. The following are some common maintenance measures:

1. Daily maintenance

In daily use, it is necessary to regularly check the wear of vulnerable parts such as hammers, impact plates, and sieve plates. If severe wear is found, it should be replaced in a timely manner. At the same time, it is necessary to regularly clean the accumulated materials and debris inside the equipment to maintain its cleanliness.

2. Regular inspections

Regular comprehensive inspections should be conducted on the equipment, including the motor, reducer, bearings, and other parts, to ensure the normal operation of each part. Any issues discovered should be promptly addressed to prevent them from escalating.

3. Lubrication and maintenance

Each part of the vertical impact crusher requires lubricant lubrication, and each lubrication point should be regularly inspected and lubricated to ensure the normal operation of the equipment. At the same time, the lubricating oil should be replaced regularly to maintain the cleanliness of the lubrication system.

4. Maintenance and upkeep

For vulnerable parts with severe wear and tear, they should be replaced in a timely manner to avoid affecting the normal operation of the equipment. At the same time, necessary adjustments and repairs should be made to the equipment according to its actual usage to ensure its performance and lifespan.

In summary, as an important crushing equipment, the working principle and maintenance of the vertical impact crusher are the key to the normal operation of the equipment. In daily use, equipment maintenance and upkeep should be strengthened, and any problems that may arise should be promptly addressed to ensure the stability and reliability of the equipment. At the same time, qualified vulnerable parts and lubricants should be selected to avoid equipment failures caused by the use of inferior products. Through reasonable maintenance and upkeep, the service life of vertical impact crushers can be extended, and the production efficiency and economic benefits of the equipment can be improved.
