prolonging the service life of the crusher hammers
There are some reasons which can effectively prolonging the service life of the crusher hammers :
1)According to design model, appropriate control of feed size, it is strictly prohibited to exceed the design maximum limit the size of the material into the machine.
2)Choose suitable feeding equipment, if the plate feeder and vibrating feeder to feed, guarantee the stability of feed evenly, avoid the uneven feed of the impact to equipment and invalid operation.
3) Due to the hammerhead quality casting error, hammer in use process should be according to the current situation, eye, right on time, so that the hammer head even wear and rotor balance operation.
4) Replacing new hammer head is best for weighing, according to the average quality is divided into several groups, each group are equal in quality requirements, otherwise the rotor unbalance is easy to cause vibration when the phone is switched on.
5) When parking to check between hammer and screen article, screen and the screen between the gap and adjust when necessary, and regular replacement screen. Because the cost of the hammer head higher than article sieve, compared with the old bar, new bar is hammer head can use 4-5 a class.
6) Hammer frame is cast steel material, and material contact less, but when the crusher to enter into metal or lining board fall off, easy to cause the hammer plate damage or bend, at this time will change it in time, otherwise easy to cause vibration hammer head loss.
7) Hammer frame side plate and the chassis sides due to the material impact, side hammer plate wear serious, in order to prolong the service life of side plate, can be in the circumference of the side plate surface and side near the side panel welding wear-resisting layer.
8) Due to the friction easy to wear and tear on both ends of the spindle, installation time want to add two in the diameter of axle shaft sleeve, the package to protect the shaft diameter of axle.
9) After the bearing wear to repair and adjust in a timely manner. Bearing wear generally should be according to the new size to grind bearing shell, after adjusting shim thickness, make reasonable clearance, in order to form effective lubricant film.
10)Power and speed of the rotor, in addition to the direct relationship with the crusher production capacity, as well as relationship between the extent of impact hammer head hardened, to prolong the service life of crusher hammers, but also to distinguish the hammer material, material for high manganese steel hammer head, large enough to ensure that its impact, for the small high chrome hammer, but just the opposite, will control it can’t have too big impact.
11)Choose a good casting which can keep quality.
