1. Equipment inspection
    ① When the new equipment is put into operation, the operator on duty conduct a inspection of the machine before starting it. Including the tightening of motors, fixed parts, belt drives, bearing seals, and electrical switches.
    ②The main parts of the machine, such as blow bars, counterattack liners, and liners, be inspected weekly for wear. If parts are found to be severely worn during the inspection, they should be replaced in time.
    ③Check the bolts and anchor bolts at various parts every day to see if they are loose or damaged, and tighten or replace them in time.
    ④ Inspect each part of the joints and welds every week for cracks and breaks. If they occur, they be re-welded to ensure safe production.
    In order not to affect the operation of the impact crusher, the impact crusher be inspected on time when working. And the desired amount of crushing is to meet the customer's expected requirements, in addition to timely inspections, but also regular maintenance, such as lubrication and overhaul.     2. Equipment lubrication
    Frequent attention and timely lubrication of the friction surface can effectively extend the service life of the equipment. The lubricating oil used in the counter-breaking 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 replaced every three months. Grease once, use clean gasoline or kerosene to carefully clean the bearing when changing the oil. The grease added to the bearing housing is 50% of the volume.
    3. Adjust
    It is also very important to adjust the relevant parts during the crushing operation of the impact crusher. Regular adjustment of the gap between the rotor and the impact liner can effectively control the discharge specifications at any time and provide users with qualified materials. It should be noted that when the rotor of the stone crusher is running, the gap between the rotor and the opposed bushing cannot be adjusted. In addition, the adjustment work between the bottom of the feed inlet and the gap between the blower should be done regularly.
    4. Repair
    Even if the maintenance is good, the impact crusher will inevitably have various minor problems after a certain number of years of use. Maintenance is to reduce and prevent the occurrence of failures, but when failures inevitably occur, repairing minor failures in a timely manner can effectively reduce the frequency of replacement of parts and reduce the severity of the problem. The impact crusher repair includes minor repair, medium repair and overhaul, and repairs should be carried out according to the actual conditions during the specific operation.
