Common faults and solutions of sand making machines

1. Abnormal vibration of sand making machine
If the material entering the sand making machine is too large to cause abnormal vibration, the feeding particle size of the stone can be checked.

When the impeller of the sand making machine wears unevenly, it will cause abnormal vibration of the machine. At this time, the damage of the impeller and the alloy hammer head can be checked. If there is any damage, it should be repaired and replaced immediately if necessary.

The imbalance of the impeller of the sand making machine causes abnormal vibration, and the balance of the sand making machine needs to be adjusted. Abnormal vibration caused by improper foundation of sand making machine, check whether the anchor bolts are loose, and fix it immediately.

2. The bearing of the sand making machine heats up
The lack of oil and too much oil in the bearing of the sand making machine will cause the bearing to heat up. You can check the oil level when it is hot.

Damage to the bearing of the sand making machine will also cause the bearing to heat up, so it is necessary to check and replace the bearing in time.

If the upper cover of the bearing body of the sand making machine is too tight, the bolts should be adjusted to properly adjust the looseness.

3. Sand making machine belt turning
The belt of the sand making machine is worn and can be replaced with a new one.

There may be a problem with the belt installation and the pulleys need to be adjusted in the same plane.

Check the quality of the V-belt of the sand making machine to see if there is any problem with the quality.

4. The discharge particle size of the sand making machine is too large
Check the damage of the alloy hammer head and the side impact plate of the sand making machine, and the alloy hammer head and the side impact plate can be repaired and used, and can be removed and replaced if necessary. Check the particle size of the material of the sand making machine. The material is one of the key factors affecting the output of the sand making machine. If the particle size is too large, the output particle size of the sand making machine will be too large.

5. The impeller is stuck
When the inside of the crusher enters metal and other hard objects, the impeller of the sand making machine may be stuck, causing the equipment to fail to work. Therefore, the hardness of the material should be strictly controlled, and the entry of unbreakable objects is prohibited.

6. The bearing is locked or the spindle is broken
If it is caused by the fracture of the spindle, it is necessary to repair or replace the worn spindle. If it is caused by the locking of the bearing, it is necessary to find out the cause of the locking, install the bearing correctly, ensure that the bearing has a certain working clearance, and do a good job of lubricating the bearing, otherwise the problem cannot be fundamentally solved.

7. There is a problem with the device connection line
If the connecting line is broken or has poor contact, the sand making machine will also suddenly stop, especially when there is no sound without warning, it is likely that the connecting line has a problem.
