Extruder feed hopper has bridging phenomenon Problems and solutions in the production process of plastic extrusion products

Possible reasons for bridging:

1. The speed of the feeder is unstable.

2. The traction motor has low horsepower and overload or unstable speed.

3. The mixing time is short, the temperature is low, the material composition, proportioning, particle size configuration, uneven mixing or high water content, wet, agglomeration, so that the extrusion speed is disordered.

4. The set temperature of the feeding section of the extruder is too high, the cooling of the feeding hopper is not good or the taper is too small.

5. Calcium carbonate is not activated or the dosage is too large.

Approach:

1. Properly adjust the feeder speed.

2. Deal with the problems related to the tractor and adjust the extrusion speed appropriately.

3. Check for and deal with recipe problems.

4. Check the feeding hopper, increase the cooling of the feeding hopper and reduce the temperature of the feeding section of the extruder as appropriate.

5. Use activated calcium carbonate or reduce the content of calcium powder in the formula.
