Impact Crusher is widely used in building materials, ore crushing, railway, highway, energy, transportation, energy, cement, mining, chemical and other industries crushing work. So, impact crusher in the course of maintenance work should be how to do it?
First, check the machine
1, crusher machine running smoothly point, when a sudden increase in the amount of vibration machine should stop immediately identify the reasons for cancellation.
2, under normal circumstances, bearing long should not exceed 35 degrees, the maximum temperature should not exceed 70 degrees, as more than 70 degrees, should be immediately stopped, identify the cause.
3, when the board hammer wear limit is reached using a U-turn sign, timely replacement.
4, after assembly or replacement plate hammer, must maintain rotor balance, static balance does not exceed 0.25kg.m.
5, when the rack liner wear and should be replaced to avoid wear cabinet.
6, each to be checked before starting the bolts fastening the status of all.
Second, after opening and closing the cover
When the racks lining, back lining, board hammer wearing parts need to be replaced after wear and tear, or machine malfunction need to eliminate, the use of the ratchet device open and close the cover, replacement and repair.

1, the constant attention and timely manner lubrication friction surface.
2, the machine used in lubricating oil, should be determined based on the location of the crusher machines, temperature and other conditions, the general use of calcium - sodium based lubricants.
3, each working eight hours after the first filling oil to the bearings, grease once every three months, when the application of clean gasoline or kerosene oil change carefully cleaned bearings, adding grease inside the bearing is 50% by volume .
