How to solve the sudden stop of sand making machine?

Sand making machine is an important equipment in sand making process, which is composed of feed hopper, distributor, crushing chamber, impeller body, main shaft assembly, base, transmission device and motor, etc. In this article, we share with you 7 reasons for the sudden shutdown of the sand making machine and the countermeasures.

1. The material in the crushing chamber is blocked

If the material in the crushing chamber is blocked, the material shall be cleaned. In the subsequent use, materials with large particle size or high water content are forbidden to enter the machine, and the feeding shall be kept uniform to avoid excessive feeding.

2. V-belt is too loose

Check if the V-belt is too loose or loose.

If it is too loose to stop the machine, it is necessary to adjust the tightness of the V-belt. If the V-belt loses its tightness due to long-term use, it needs to be replaced.

3. Improper working voltage

When the working voltage of the production site is too low, it is not enough to maintain the normal operation of the sand machine and shut down.

It is necessary to select a voltage that meets the requirements of the equipment.

4. Internal parts fall off

If there is metal collision sound before the equipment is shut down, it may be that some parts in the crushing chamber fall down and cause the sand making machine to shut down suddenly.

It is necessary to check the internal part of the equipment and make sure that it is installed correctly after the internal parts fall off.

5. Impeller stuck

When metal and other hard objects enter the crusher, the impeller of the sand making machine may be stuck, resulting in the equipment unable to work.

The hardness of the materials shall be strictly controlled, and it is forbidden to enter the materials that cannot be broken.

6. The main shaft is broken or the bearing is locked

If it is caused by the fracture of the main shaft, it is necessary to repair or replace the worn main shaft.

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 in the lubrication of the bearing, otherwise the problem cannot be fundamentally solved.

7. There is a problem with the equipment connecting line

If the connecting wire breaks or has poor contact, the sand machine will stop suddenly, especially when there is no sound without any sign, it is likely that there is a problem with the connecting wire.

If the connecting line of the equipment is broken or in poor contact, it shall be adjusted or replaced in time.
