Blocking is a common problem of sand making machines. Once blocking occurs, the machine production will stop, and then the machine must be stopped for processing. At this time, the production process will be delayed, the average efficiency of production will be reduced, and unnecessary losses will be caused to the enterprise. Today, the editor will introduce the phenomenon of blocking, its causes, and solutions.

1. The material size is too large

 

If the size of the material entering the sand making machine exceeds the size of the sand making machine specification, it will cause blockage. The solution is to ensure that the material size meets the equipment requirements. ‌

 

2. Excessive humidity

 

If the material has a high moisture content, it may adhere to the inner surface of the sand making machine, causing blockage. The solution is to control the humidity of the feed or pre-heat it. ‌

 

3. Uneven feeding speed

 

The feeding speed and processing speed are not well matched, such as fast feeding, slow crushing, and slow discharging, which will cause material blockage. The solution is to adjust the feeding system to ensure uniform and continuous feeding. ‌

 

4. Improper maintenance of the equipment

 

The stone powder or debris accumulated inside the sand making machine will block the equipment. ‌The solution is to clean and maintain the equipment regularly. ‌

 

5. Equipment wear

 

The crusher, screen and other parts inside the sand making machine are seriously worn, resulting in the material not being able to pass smoothly. ‌The solution is to check and replace the worn parts regularly. ‌

 

6. Improper adjustment of the discharge port

 

Improper adjustment of the discharge port will cause slow material discharge or blockage. ‌The solution is to adjust the discharge port to ensure smooth discharge of the material. ‌

 

7. Mismatch of production line equipment

 

The material that enters later enters before the material in front is completely crushed, causing blockage. ‌The solution is to ensure that the production line equipment matches to avoid mismatch in production capacity. ‌

 

8. Improper manual operation

 

The operator has not been systematically trained, and improper operation leads to blockage. ‌The solution is to train the operator to ensure that he is familiar with the equipment operation process before taking up his post.

 

The main reasons for blockage in sand making machines include material size that is too large, humidity that is too high, uneven feed speed, improper internal equipment maintenance, equipment wear, improper discharge port adjustment, mismatch of production line equipment, improper manual operation, etc. Solutions to these problems include strictly controlling feed particle size and humidity, regularly maintaining and cleaning equipment, adjusting the feed system to ensure uniform feeding, regularly checking and replacing worn parts, adjusting the discharge port, ensuring matching of production line equipment, training operators, etc.
