The Maintenance of the Impact Crusher

May 31, 2016

The impact crusher is the common crushing equipment used in the sand production line and the stone crushing process, which is famous for the nice particle shape of its final product. If you want to prolong its service life, it is very important to maintain it well. Now, we will share our impact crusher maintenance tips with you.

1. After the operation of the new impact crusher, it must be examined every shift.

2. After the operation, the electric motor and the lubrication of the impact crusher should be examined weekly. It should be checked whether the fixed parts are fastened well and the abrasion situation of some parts, including the belt transmission, bearing seal, impact plate, etc. Besides, the rules and regulations of the examination of the machine should be set and replaced regularly.

3. The space between the rotor and the impact plate should be adjusted. While the rotor of the impact crusher is rotating, the space between the rotor and the impact plate should not be adjusted. If some material of block gets stuck between the impact plate and the plate shell, you’d better adjust the space again by lifting the impact rack slightly, which can make it easy to feed the material into the machine. If impact racks are not enough, a wooden board can be put at the loose tension rod. The space between the rotor and the impact plate is adjusted by the adjustment device of the machine. The bolt sleeve is firstly loosened. Then the long nut is screwed to make the rod move up. When it has been adjusted well, the bolt sleeve is fastened.

4. The quick-wear parts should be replaced regularly. At the replacement time, the back rack at the top of the machine should be opened firstly.

5. When the blow bar of the impact crusher has been worn to a certain extent it should be adjusted or replaced immediately to avoid the damage of the fasteners with other parts.

6. The back shell at the top of the machine is opened. The cotter, slotted nut, and the bolt used to fix the impact plate should be removed to replace the worn impact plate.

7. Due to some causes, including too much or not enough lubricant, dirty lubricant, and the damage of the bearing, the temperature of the machine is too high. Thus, the replacement of the bearing of the impact crusher is important in the sand production line.
