When the rubber extruder is extruding, due to the excessive amount of calcium carbonate, it is easy to cause the material to be blocked in the barrel, and the screw of the rubber extruder barrel cannot be rotated. How to solve this situation?
Generally speaking, most of the reasons for the blockage of the barrel and screw of the rubber extruder are because there are foreign objects inside, so the main solution is to clean up the foreign objects.

　　The method of cleaning is to increase the temperature of the barrel so that the materials inside can melt, and then keep it warm for a period of time and start slowly. During this time, the temperature needs to be controlled to prevent the materials inside from being burnt.
If you find that the screw of the rubber extruder barrel is still unable to rotate normally after cleaning the foreign body, you need to consider whether there is a hard object stuck in the front part, and see if the hard object can be pushed out, and be careful not to use brute force to avoid the machine. The tube is scrapped.
　　If it still doesn't work, you need to replace the barrel and screw with a new one.
