Hammer crusher is the use of high-speed rotation of the hammer impact material, make the material along the natural fractures, bedding planes and other vulnerable part of the fracture and joint broken machine, widely used in mining, metallurgy, building materials and electric power industry. Hammer crusher in the process, due to the impact of the material and the friction is inevitable the hammer, liner, grate and other parts wear and failure, the head is easy wear parts mainly, its consumption is great, need to reserve a large number of spare parts, which not only occupied capital, and affect the normal production of enterprises. How to use the hammer crusher to improve service life?

Correct use and scientific maintenance of the device is always in good condition, effective way to prolong the service life of the hammer. If improper use and maintenance, not only easy to cause equipment failures, such as vibration, noise, heat, wear, and is bound to lead to the service life of the hammer is lower. Hammer crusher should pay special attention to the following points in the daily use and maintenance:

  1. according to the design model, the proper control of feed size, strictly beyond the design of the maximum size of the material, man-machine

  2. choose the appropriate feeding equipment, such as feeding by plate feeder or vibrating feeder, to ensure uniform and stable feeding, and avoid the impact of the uneven feeding on the equipment and ineffective operation

  3. due to the quality of the hammer casting error, the use of hammer in the process should be in accordance with the current situation, on time inverted eye, flip, so that the hammer uniform wear and rotor balancing

  4. when changing the new hammerhead, it is best to weigh, divided into several groups according to the average quality, the quality requirements of each group are equal, otherwise the rotor is unbalanced when it is switched on, and it is easy to cause vibration

  5. when parking to check between the hammer and the sieve, sieve and sieve the gap between, and adjust if necessary, and regular replacement of the sieve. Because of high cost than the hammer sieve, sieve and sieve the new old compared with 4 - to hammer 5 classes.

  6. hammer crusher hammer frame is made of cast steel, less contact with the material, but when the crusher into metal or lining off, easy to cause the hammer disc broken or bent, then should promptly be replaced, otherwise easy to lose hammer cause vibration.

  7. the side hammer disk and the shell side of the hammer frame are impacted by the material, and the wear of the side hammer disk is serious. In order to prolong the service life of the side disk, the wear-resistant layer can be deposited on the circumferential surface of the side plate and the side of the side plate

  8. because of the friction in the running, the spindle shaft diameter at both ends is easy to wear. When installing, two shaft sleeves are added to the axle diameter, so that it is wrapped on the shaft to protect the axle diameter

  9. the bearing should be repaired and adjusted in time after the wear of the bearings. The bearings should be scraped and adjusted according to the new size, and the thickness of the gasket should be adjusted so as to keep a reasonable gap so as to form an effective lubricating film
