Common faults during the operation of 300 tons per hour sand making equipment are as follows:

1. Abnormal vibration of the sand making machine during production

1. The material entering the sand making machine is too large, you can check the feed particle size.

2. The impeller of the sand making machine is unevenly worn. Check the wear of the impeller and the alloy hammer. If there is wear, repair the impeller and hammer, and replace them in time if necessary.

3. The impeller of the sand making machine is unbalanced and needs to be balanced.

4. The foundation of the sand making machine is improperly handled. Check the anchor bolts and tighten them.

2. The discharge particle size of the sand making machine is too large

1. Check the wear of the alloy hammer of the sand making machine, and repair or replace the alloy hammer.

2. Check the wear of the side impact plate of the sand making machine and replace it if necessary.

3. Check the feed particle size of the sand making machine. Too large feed particle size will also affect the discharge particle size.

3. Sand making machine bearing heating

1. Sand making machine bearing lacks oil, check and refuel in time; over-fueling will also cause the bearing to heat up, so be sure to check the oil level when refueling.

2. Sand making machine bearing is damaged, check and replace the bearing in time.

3. The upper cover of the sand making machine bearing body is too tight, and the bolts should be adjusted to a moderate tightness.

4. Sand making machine belt flipping

1. It means that the sand making machine belt is worn and the V-belt needs to be replaced.

2. The belt conveyor assembly problem requires the pulley to be adjusted on the same plane.

3. Check the quality of the V-belt itself.
