  If the sand making machine is used for a long time, it is inevitable to have some faults. When the sand making machine is abnormal in the use process, the operation should be stopped immediately and the equipment should be troubleshooting to avoid unnecessary losses.The following is a summary of several problems and solutions:

1、 Abnormal vibration of sand making machine

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

2. When the impeller wear degree of the sand machine is not uniform, it will cause abnormal vibration of the machine. At this time, the wear of the impeller and alloy hammer can be checked. If there is wear, it can be repaired and replaced in time if necessary.

3. The unbalance of impeller of sand making machine leads to abnormal vibration, so it is necessary to adjust the balance of sand making machine.

4. For abnormal vibration caused by improper foundation treatment of sand making machine, check whether the anchor bolt is loose and fix it in time.

2、 Bearing heating of sand making machine

1. The lack of oil and too much oil in the bearing of sand making machine will make the bearing hot. When heating, check the oil level.

2. Sand machine bearing damage will also lead to bearing heating, timely inspection and replacement of bearings.

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

3、 Belt overturning of sand making machine

1. The belt of sand making machine is worn and can be replaced with a new one.

2. There may be a problem with the belt installation and the pulley needs to be adjusted on the same plane.

3. Check the quality of the triangle belt of the sand making machine to see if there is any quality problem.

4、 The discharge particle of sand making machine is too large

1. The alloy hammer head and side impact plate can be repaired and used, and can be replaced if necessary.

2. Check the particle size of the sand making machine. As one of the factors affecting the output of the sand making machine, if the grain size is too large, it will also cause the discharge particle size of the sand making machine to be too large.

5、 There is metal collision sound in the sand making machine

1. The inner lining plate or impeller of the sand making machine falls off, so it is necessary to stop the machine and fasten the parts again.
