How to solve the problem of blockage of screw and barrel of rubber extruder

When the rubber extruder is extruding, due to the excessive amount of calcium carbonate, it is easy to cause the material to be blocked inside the barrel, and the screw and barrel of the rubber extruder cannot rotate. How to solve such a situation? Generally speaking Most of the reason for the blockage of the screw and barrel of the rubber extruder is because there are foreign bodies inside, so the solution is mainly to clean up the foreign bodies. The cleaning method is to raise the temperature of the barrel so that the material inside can be melted, then keep it warm for a period of time, and start it slowly.

 

During this period, the Extruder screw barrel temperature needs to be controlled to prevent the material inside from scorching. If after cleaning the foreign objects, it is found that the barrel screw of the rubber extruder still cannot rotate normally, then it is necessary to consider whether there is a hard object stuck in the front end to see if the hard object can be pushed out, and be careful not to use brute force to avoid the machine Cartridge is scrapped. If it still does not work, then you need to replace the new barrel screw.
