Metering feeder, and system and method for kneading and extruding material
A system for kneading and extruding a material includes a crusher for crushing the material into coarse particles, an extruder for conveying and extruding the material crushed by the crusher, a gear pump for receiving and discharging the material extruded from the extruder, and a kneading and extruding apparatus for kneading the material discharged from the gear pump and continuously extruding the kneaded material. Therefore, a material is accurately quantified and highly uniform, resulting in reduced product variations and ensured consistent quality.
1. A system for kneading and extruding a material, comprising:
a crusher for crushing the material into coarse particles;
an extruder for conveying and extruding the material crushed by the crusher;
a gear pump for receiving and discharging the material extruded by the extruder;
a kneading and extruding apparatus; and
means for applying a resistance to the material discharged from the gear pump and supplying the material to the kneading and extruding apparatus,
wherein the means for applying a resistance is disposed immediately in front of the kneading and extruding apparatus.
2. The system according to claim 1 , wherein the means for applying a resistance to the material discharged from the gear pump directly contacts the kneading and extruding apparatus.
3. The system according to claim 1 , wherein the means for applying a resistance to the material discharged from the gear pump is a resistance plate directly contacting and covering an input port of the kneading and extruding apparatus for the material discharged from the gear pump.
