Maintenance Matters Needing Attention For Impact Crusher
Impact crusher is a new type of high-efficiency crushing equipment, which can crush materials with a compressive strength not exceeding 350 MPa and a side length of 100-500 mm or less. Since the impact crusher is a machine that mainly uses impact energy to crush materials, when working, the hard materials are in high-strength contact with the blow hammer, impact plate, lining plate and other components, making these components particularly easy to wear, so in order to ensure the equipment to work normally and prolong its service life, daily maintenance and maintenance of the impact crusher must be done. The specific maintenance points are as follows:
1. Strictly check before starting
Impact crusher should be strictly inspected before starting up. The inspection contents mainly include whether the bolts of the fastening parts are loose, and whether the wear of the easy-to-wear parts is serious. If there is a problem, it should be dealt with in time. If the wearing parts are found to be seriously worn, they should be replaced in time.
2. Start and stop according to the operating regulations
When starting up, it must be started in sequence according to the specific operation regulations of the impact crusher. First, confirm that all parts of the equipment are in normal condition before starting. Secondly, when the equipment is started, it must run for 2 minutes with no load. If there is an abnormal phenomenon, stop it immediately for inspection, and restart it after troubleshooting. When shutting down, ensure that the material is completely crushed, and ensure that the machine is in an empty state when the machine is started next time.
3. Pay attention to check the operation of the machine
During the operation of the impact crusher, it is necessary to check the condition of the lubrication system and the temperature of the rotor bearing frequently. Regularly add or replace lubricating oil. The temperature of the rotor bearing should not exceed 60 degrees normally, and the maximum temperature should not exceed 75 degrees. If the upper limit is exceeded, stop immediately to check and solve the problem.
4. Continuous and uniform feeding
Impact crusher needs to use a feeding device to ensure uniform and continuous feeding, and to make the material to be crushed evenly distributed on the entire length of the working part of the rotor, which can not only ensure the processing capacity of the machine, but also avoid material blockage. The size of the working gap can be observed by opening the inspection doors on both sides of the machine. When the gap is not suitable, the discharge gap can be adjusted by adjusting the device.
5. Do a good job of lubrication and maintenance
It is necessary to do a good job of lubricating the friction surfaces and friction points of the equipment in time. The use of lubricating oil should be selected according to the use location of the impact crusher, temperature and environment, etc. In general, calcium-based lubricating oil is used, and general-purpose lithium-based lubricating grease can be used in areas with poor environment. The equipment needs to be filled with lubricating oil every 8 hours of operation, and the lubricating oil should be replaced every three months.
6. Do a good job of sealing and ventilation and dust removal
Impact crusher mainly uses impact energy to crush materials during operation, so it will have a strong impact, and the dust generated is large, which is easy to affect the working environment. Therefore, the impact crusher must be tightly sealed and ventilated in time for dust removal.
Only operating the impact crusher in strict accordance with the operation steps and correctly is the best maintenance for the equipment. Moreover, the daily maintenance and maintenance work cannot be ignored. From the above, we found that there are many steps, so we must take the maintenance work of the crusher seriously. Only with more stable performance of the device, it can bring more benefits to users.
