Impact crusher is common crushing equipment in the field of sand and gravel. It is often used in the secondary or tertiary crushing process in the crushing production line. Due to its large crushing ratio, the crushed sand and gravel have a good shape and are widely used.
However, as we all know, the impact crusher adopts the principle of impact crushing. During the crushing process, the material is impacted back and forth to achieve the purpose of crushing. Under such a working process, the hammer head and plate hammer are much worn, so how to maintain the impact crusher?
- Equipment inspection
In the working process of the impact crusher, the daily inspection work should be done first. When the new machine is put into operation, the staff on duty must conduct a comprehensive inspection of the machine before working. The inspection content includes the equipment motor, the fastening of the fixed parts, the belt drive, and the bearing seal. The situation of electrical switches, the main parts of the machine, such as blow bars, counterattack liners, and liners, must be inspected weekly for wear. If parts are found to be severely worn during the inspection, they should be replaced in time. - Equipment lubrication
Frequent attention and timely lubrication of the friction surface can effectively extend the service life of the equipment. The lubricating oil used for lubrication should be determined according to the location of the machine, the temperature and other conditions. Generally, calcium-sodium-based lubricating oil can be used. Lubricating oil is added to the bearing after every eight hours of work, and the lubrication is changed every three months. Grease once, clean the bearings with clean gasoline or kerosene when changing the oil, and add 50% of the volume of the grease in the bearing housing. - Adjust
In the working process, the relevant parts should be adjusted regularly, and the gap between the rotor and the impact liner should be adjusted regularly, which can effectively control the size of the discharge particle size and provide users with qualified materials. In addition, the adjustment work between the bottom of the feed inlet and the gap between the blow bars should be done regularly. When adjusting it, the square steel on both sides of the frame should be removed, and then the square steel should be drawn out, and then turned in after rotating. - Repair
The maintenance of the impact crusher is indispensable to the repair of the crusher, and the maintenance of minor faults in time can reduce the replacement rate of parts. The repair work of the impact crusher includes minor repair, intermediate repair and overhaul, which should be repaired according to the specific conditions during the specific operation.
Whether it is a impact crusher or other types of crushers, due to long-term work in a relatively harsh environment, the equipment is prone to failure, thereby reducing the service life of the equipment, so daily maintenance and maintenance must be done during use. In order to improve the efficiency of the equipment and maximize the benefits!
