In view of the factors affecting the life of the crusher, the correct use and scientific maintenance of the equipment is always in good condition, which is an effective way to extend the service life of the hammer.
1, strict control of material size and quantity
According to the design model of the crusher, the feed size is properly controlled, and the material beyond the design maximum limit size is strictly prohibited to enter the machine, and the crusher is strictly controlled to work within the design limit parameters.
2, crusher feed evenly full
Select suitable feeding equipment, such as plate feeder, vibrating feeder, flat belt, etc., to ensure uniform and stable feeding, to avoid the impact of uneven feeding on the equipment and ineffective operation.
3, strictly control the quality of the hammer
Due to the quality error of the hammer casting, the selection should avoid the selection of those with trachoma, porosity and other casting defects of the hammer, the hammer should be used according to the current situation, on time, turn over, so that the hammer uniform wear and rotor operation balance.
4. Reasonable arrangement of hammer head installation
The hammer head and hammer handle are arranged in a cross way. Before installation, the hammer head is arranged in a weight group according to the axial light on both sides and the heaviest symmetrical group in the middle. The weight error of hammer head and hammer handle assembly in radial position shall not exceed 0.1kg; Hammer head The hammer handle rotates flexibly.
5, reasonable control of the crushing gap and timely adjustment
In the process of use, with the wear of the hammer head, the gap between the hammer head and the grate will gradually change, in order to ensure the crushing efficiency, the gap must be adjusted in time. At the same time, too small clearance adjustment will cause accelerated wear of the hammer head, and according to experience, the clearance should be controlled between 20-30mm.
6. Strictly control the iron to eliminate abnormal consumption of the hammer head
Iron remover should be installed on the feed belt entering the crusher to control the entry of debris such as iron blocks into the crusher.
7. Surfacing wear-resistant layer
It is necessary to clean up the accumulated material of the crusher in time, because of the existence of the accumulated material, the crusher hammer will be subjected to serious friction and wear and sharply reduce the service life of the hammer head. For the side hammer head and the end part of the hammer head with more serious wear, the service life of the hammer head can be properly extended by surfacing the wear-resistant electrode.
