Impact crusher maintenance cheats and crusher rotor replacement program

1. After the new machine is put into operation, a comprehensive inspection of the counter-attack must be carried out after each class is completed.

2. Perform a comprehensive inspection of the motor and lubrication that is broken after the weekly operation. The inspection contents include the fastening of the fixed part, the belt drive, the bearing seal, the counter-lining, the wear of the lining plate, and the full-position inspection, and establish a regular maintenance and replacement system in combination with the maintenance cycle.

3. Adjustment of the gap between the rotor and the counter lining: When the rotor of the impact crusher is running, the gap between the rotor and the counter lining cannot be adjusted. If the material is stuck between the counterattack plate and the plate shell, it is recommended to raise the counter-attack slightly between the re-adjustment gaps, so that the feed of the block will become loose and the counter-attack frame can be easily adjusted. If the counter-attack is not enough, you can pat on the loose lever (protected with a piece of wood). The clearance between the rotor and the counter-liner is done by the adjustment device of the machine. First loosen the bolt sleeve and then turn the long nut. The drawbar moves upwards and is adjusted to tighten the screw sleeve.

4. Replace the wearing parts: When replacing the wearing parts with the impact crusher, first open the rear frame. When using, first remove the connecting bolts of the rear upper frame and the middle case, then use a wrench to screw the hex head part of the flip device, and then the upper frame is slowly opened. At the same time, the rear frame can be suspended by the hanging device above the rack. Repeat the above process, that is, close the upper shelf.

5. Plate hammer: When the counter-attack hammer is worn to a certain extent, it should be adjusted or replaced in time to avoid damage to fasteners and other components.

6. Lining: After opening the upper cover, remove the split pin, slotted nut and bolt used to fix the counter-lining, then replace the worn backing liner. If installing a new counter lining, reverse the above steps immediately.

7. Bearing: The temperature may be too high due to excessive or insufficient grease, dirty grease and bearing damage. The replacement of the impact crusher plays a key step in the sand production line.

It is very important to change the rotor technology of the crusher. Today, Xiaobian uses the hammer crusher as an example! Let me share the replacement method of the crusher rotor!

The hammer crusher is a section of crushing crusher that directly crushes materials with a maximum particle size of 600-1800 mm to 25 or less. The hammer crusher rotor is mainly composed of a main shaft, a hammer plate, a hammer head, a hammer shaft, a spacer sleeve, a locking device, a bearing, a bearing seat, a sealing device, a pulley, etc., wherein the rotor main shaft is the most important, and the hammer crusher rotor main shaft Equipped with flat keys, two discs, spacers, rocker arms and toothed and round ring hammers.

However, in the daily production, the hammer crusher rotor will have such problems as:

First, the hammer crusher rotor is initially unbalanced.

Second, the hammer crusher rotor spindle deformation, bending, unbalance. Reason: It may be because of long-term crushing operations.

Third, the repair and replacement of the hammer on the rotor of the hammer crusher. Reason: The hammer crusher has a very fast wear and has a long service life and needs to be replaced naturally.

Note: Hammer crusher hammer arrangement is strictly in accordance with a certain weight ratio. Some hammer heads are seriously worn, and the rotor rotation will be seriously unbalanced, resulting in damage to machinery and equipment and affecting production efficiency.

Fourth, the hammer crusher rotor bearing wear and so on. When the hammer crusher rotor needs to be replaced in the above several cases, how to replace it? The crusher rotor replacement scheme (taking the slag crusher to replace the rotor as an example):

1. Adjust the clearance between the rotor and the counter-liner. When the slag breaker rotor is in operation, the gap between the rotor and the counter lining cannot be adjusted. If the material stays between the counterattack plate and the plate shell in a block, the counter-attack frame can be raised slightly before the gap is re-adjusted, so that the feed of the block will become loose and the counter-attack frame can be easily adjusted.

2. Replacement of wearing parts. When replacing consumables, first open the rear upper frame, then remove the connecting bolts of the rear upper frame and the middle case, and then slowly open the rear upper frame.

3. Replacement of the hammer. First open the rear upper frame with the flip device, then turn the rotor by hand, turn the hammer to be adjusted or replaced to the access door, and then fix the rotor.

4. Counterattack liner replacement. After opening the upper cover, remove the split pin, slotted nut and bolt for fixing the counter-backing lining, and replace the worn counter-backing lining.

5. Adjustment of the lining plate. Adjusting the slag breaker liners requires opening the rear shelves, and all liners are allowed to be interchanged in areas with heavy wear and lighter wear.
