The impact crusher can process compressive strength below 350Mpa, such as limestone, gypsum, concrete, etc. In order to reduce the wear caused by crushing gypsum and realize more crushing and less grinding, the manufacturer pays more attention to the maintenance of this equipment. Among them, the main bearing of fine crushing and ultra fine crushing equipment and the wear of plate hammer are easy to occur. SMMVIK Machinery will consider the actual needs of users when designing.
Maintenance measures for impact crusher:
1. Check the inside of the equipment, especially to see whether the plate hammer is seriously worn. Since the plate hammer has a great impact on the discharge particle size, it is also necessary to check the condition of other vulnerable parts, including the degree of wear and whether there are cracks.
2. During the operation of the impact crusher, the dust is relatively large. In addition to well sealing all parts of the crusher, ventilation and dust collection equipment shall also be set in the workshop.
3. The clearance between the reaction plate and the plate hammer shall be gradually adjusted to the minimum according to the work needs. After the adjustment, the rotor shall be manually rotated to check whether there is impact. After the adjustment, the sleeve nut shall be locked.
4. Always observe the temperature rise of the main bearing of the rotor. Under normal conditions, it is about 60 ℃, and the higher temperature shall not exceed 75 ℃. If the temperature rise exceeds the higher requirements, stop the machine immediately for inspection and take effective measures to solve the problem.
5. During operation, the vibration, temperature and sound shall be regularly inspected according to the patrol inspection requirements.
6. The main motor can not be stopped until all the materials in the crusher are discharged.
The plate hammer of the impact crusher adopts relatively new manufacturing technology, unique structural design, no tension and crack, and the particle shape is quite good. At present, the multi-element high chromium cast iron gradually replaces the high manganese steel material. Through reasonable improvement, the performance of the plate hammer is greatly improved, the production efficiency of the equipment processing gypsum is improved, and the service life of the plate hammer is also extended.
