The manufacturer of Screw and Barrel for Rubber Machine will take you to know: the reasons for the abrasion of the rubber extruder barrel and the repair method

The manufacturer of Screw and Barrel for Rubber Machine tells you that although the surface hardness of the rubber extruder barrel is higher than that of the screw, and its service life is higher, the barrel will also cause wear or tear due to long-term use. Damage caused by improper use.

1. Reasons for the abrasion of the rubber extruder barrel:
1. The manufacturer of Screw and Barrel for Rubber Machine tells you that during the production process, if the temperature of the process is too low, the torque will increase suddenly. Once the torque exceeds the tolerance range of the screw, the screw will be twisted.
2. The Screw and Barrel for Rubber Machine manufacturer tells you that if there are some fillers in the material, it will increase the degree of wear of the screw and Jitong.
3. The screw of the rubber extruder keeps rotating in Jitong, so the material, screw and barrel are in friction state for a long time, which causes the gap between the screw and barrel to increase continuously.
4. Insufficient heat treatment hardness of the working surface of the barrel, or incorrect selection of materials, will cause the barrel to be damaged.
2. Repair of rubber extruder barrel
1. If the diameter of the barrel becomes larger due to the abrasion of the barrel, you can bore the inner hole of the barrel, grind a new size, and then configure a new screw according to the new diameter.
2. The manufacturer of Screw and Barrel for Rubber Machine tells you to recast the alloy after trimming the inner diameter of the barrel, and the thickness of the alloy is controlled within 1~2mm.
3. The manufacturer of Screw and Barrel for Rubber Machine tells you that the homogenization section of the rubber extruder barrel will wear out relatively quickly, so you can separately boring and trim this section with a bushing.
The manufacturer of Screw and Barrel for Rubber Machine tells you that the barrel of the rubber extruder is a very important part. When it is worn out, we choose whether to repair it or replace it directly. We can choose according to the economic situation.
