Contact Us If Your Rubber Extruder Encounter These Problems

1. Abnormal noise
1. If it occurs in the reducer, it may be caused by bearing damage or poor lubrication, or gear wear, improper installation and adjustment, or poor meshing. It can be solved by replacing bearings, improving lubrication, replacing gears, or adjusting gear meshing conditions.
2. If the noise on rubber extruder is a sharp scraping sound, consider the possibility of the shaft head and the drive shaft sleeve being scraped due to the deflection of the barrel position. It can be solved by adjusting the barrel.
3. If the barrel makes noise, it may be because the screw is bent to sweep the bore or the set temperature is too low, causing excessive friction of solid particles. It can be processed by straightening the screw or increasing the set temperature.

2. Abnormal vibration
If this happens at the reducer, it is caused by the wear of the bearings and gears, which can be solved by replacing the bearings or gears; if it happens at the barrel, it is due to the hard foreign matter mixed in the material, and the cleanliness of the material needs to be checked. If necessary, install a strong magnetic device in the hopper to adsorb iron filings.

3. the ring blockage at the screw entrance
This kind of failure is mainly caused by the cooling water cut-off or insufficient flow. It is necessary to check the cooling system and adjust the cooling water flow and pressure to the specified requirements. It is also possible that a large piece of recycled material in the raw material blocks the feed inlet, and the feed inlet needs to be cleaned.
