The impact crusher has high crushing efficiency, small size, simple structure, large crushing ratio, low energy consumption, large production capacity, uniform product particle size, and can selectively crush ore. It is a promising equipment. However, the impact crusher also has obvious disadvantages, that is, the blow bar and the impact plate are particularly easy to wear. So, how to maintain in daily life?
1. Check before starting the machine
The impact crusher should be strictly inspected before starting up. The inspection content mainly includes whether the bolts of the fastening parts are loose, and whether the wear degree of the wearable 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 operating regulations of the impact crusher. Firstly, confirm that all parts of the equipment are in normal condition before restarting. Secondly, after the equipment is started, it must run without load for 2 minutes. If there is any abnormal phenomenon, stop the machine immediately for inspection, and then start again 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, attention should be paid to frequently checking the condition of the lubrication system and the temperature of the rotor bearings. 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 it exceeds the upper limit, stop the machine immediately for inspection and solve it.
4. Continuous and uniform feeding
The 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. service life. You can observe the size of the working gap by opening the inspection doors on both sides of the machine, and adjust the discharge gap by adjusting the device when the gap is not suitable.
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 determined according to the place where the crusher is used, the temperature and other conditions. Generally, calcium-sodium-based lubricating oil can be used. The equipment needs to be filled with lubricating oil into the bearing every 8 hours of operation, and the lubricating oil should be replaced every three months. When changing the oil, the bearing should be cleaned carefully with clean gasoline or kerosene, and the lubricating grease added to the bearing seat is 50% of the volume.
In order to ensure that the impact crusher can run continuously in the sand making production line and extend the service life of the impact crusher, the user should carry out regular maintenance and maintenance on the impact crusher. Only the performance of the equipment is more stable. In order to bring more benefits to our users.
