Hammer crusher is one of crusher machinery that crushing the largest particle size of 600-1800 mm of material to 25 mm or below 25 mm. Hammer crusher is widely used in cement industry, chemical industry, power industry, metallurgical industry and other industries, and is suitable for crushing medium hardness materials such as limestone, slag, coke, coal and other materials. Hammer crusher like other equipment, long-term use is bound to causing a certain loss, so it is necessary that the maintenance of hammer crusher. In a Chinese ancient saying: if you want to do things well, first make everything ready for you. First-class equipment is to ensure that the premise of first-class quality. In order to hammer crusher to maintain good performance and efficient production efficiency, they need to carry out regular maintenance.

First, the daily operation must be standardized

Hammer crusher is a high-speed rotary crushing machinery, in order to ensure its normal operation, the operator must be for operation in strict accordance with the procedures. According to the order of opening and stopping to the correct operation; empting the material in the crushing cavity to ensure that the empty start; uniform feeding to avoid damage to equipment caused by metal debris; in the process of equipment, if there is abnormal sound, and immediately stop, and notify the relevant personnel and supervisors to conduct detailed inspections.

Second, pay attention to update the maintenance of equipment components

It must be regularly inspected for maintenance of hammer crusher important work components. Check the wear of the hammer on time to observe whether the hammer is crack, hammer connection is vibration or not, and do the maintenance or replacement. Check the protective cover of the transmission belt and coupler is loosening or not, whether the loose anchor bolts, and fastening in time. Check the temperature and sound the bearing, and vibration of the crusher body, if there is abnormal and timely processing. When there is severe wear and tear in machine parts, it should be promptly replaced, the rotor should be balanced after the repair.

Third, pay attention to the lubrication of equipment

Hammer crusher is one of heavy mining machinery, and good lubrication is the premise of its good operation. Always look at the lubrication to keep the lubrication system in good condition. The temperature of the rotor bearing should be kept below 60 degrees centigrade, and the maximum not more than 70 degrees centigrade, if there is over-temperature, it should identify the reasons and take measures to eliminate.
