As the core equipment for manufactured sand production, the operational stability of a sand making machine directly impacts project progress and economic benefits. However, the equipment often experiences various faults during long-term, high-load operation. Common problems include bearing overheating, abnormal discharge, and unusual metallic noises. Impeller wear and improper feed contribute to 67% of these issues. Timely diagnosis and standardized maintenance are key to reducing costs and increasing efficiency. Below is a summary of several faults and their solutions of sand making machines:

 

 Abnormal vibration of the sand making machine

 

1. If the material entering the sand making machine is too large, causing abnormal vibration, check the feed size of the stone.

 

2. Uneven wear on the sand making machine's impeller can cause abnormal vibration. In this case, check the wear of the impeller and alloy hammers. If any wear is detected, repair or replace them promptly.

 

3. Abnormal vibration caused by an unbalanced impeller requires balancing of the sand making machine.

 

4. Abnormal vibration caused by improper foundation treatment of the sand making machine requires loose anchor bolts, which can be tightened promptly.

 

Sand Making Machine Bearings are Overheating

 

1. Lack of oil or excessive oil in the sand making machine bearings can cause the bearings to overheat. Check the oil level if this occurs.

 

2. Damage to the sand making machine bearings can also cause bearing overheating. Check and replace the bearings promptly.

 

3. If the upper cover of the sand making machine bearing is too tight, adjust the bolts to loosen them appropriately.

 

The sand making machine's discharge particle size is too large

 

1. Check the wear of the sand making machine's alloy hammers and side impact plates. Repair the hammers and side impact plates, or replace them if necessary.

 

2. Check the particle size of the sand making machine's material. Excessive particle size can also cause the sand making machine's discharge particle size to be too large, as it affects the machine's output.

 

The sand making machine makes a metallic clanging sound

 

The sand making machine's internal liner or impeller has fallen off. Consumable parts need to be stopped and re-tightened.

 

* Recommended Sand Making Machine:

PLS Series Vertical Shaft Impact Crusher (Sand Making Machine)

 

Features: Combines crushing and shaping functions, suitable for fine crushing and sand making operations. Highly efficient and energy-efficient, the optimized impeller design increases crushing efficiency by over 30%. Compact and easy to maintain, it is suitable for mining and construction aggregate processing.

 

The above methods should be adjusted based on the actual operating conditions of the equipment. Regular maintenance can effectively prevent malfunctions.
