The sand making machine works at the high speed with large power, during its working process, there will have more or less problems. In order not to affect the production, we need to solve the problem quickly. When the machine works, it may appear strong vibration, which is normally caused from the three factors:

1. Strong vibration of machine body caused by large feeding granularity. If the feeding size is oversized, it will cause the strong vibration of the machine; if the size is too small, it will lead to inadequate broken, which not meet the requirement.

2. The wearing parts of the machine. If the wearing parts are worn seriously, it may cause this problem. The bad abrasion of the wearing parts on the impeller will lead to the inner working of sand making machine is not stable and strong vibration. At this time, it needs to replace the wearing part to make the inner impeller at balance condition.

3. The inner blockage may lead to the problem. The blocked impeller passage will cause the unevenly feeding of the materials. The way to solve this problem is to take out the blocked materials.
