Feed extruder composition and frequently asked Questions

Main parts and components

Screw: is the main component of the bulking machine, indicating the parameters of the screw structure are diameter, pitch, root diameter, spiral Angle and blade section structure. The length to diameter ratio of extruded parts and the gap between the screw and the inner wall of the expanding cavity also have great influence on the performance of the expanding machine.
Discharge die: It is the last checkpoint of the product through the expanding machine. It has a great influence on the shape, texture, density, appearance, characteristics of the product and the production of the expanding machine. The bearing box part is mainly composed of bearing box, spindle, bearing, shaft sleeve, left and right end cover, sealing ring and round nut. Oil filtration cooling system is mainly composed of oil pump, cooler, oil filter, valve, connecting pipe fittings and so on.

Q&A

1. Bearing wear occurs after the equipment runs for a period of time. The clearance of the bearing needs to be adjusted;
2. Steam flows back into the feeder, causing the feeder to be blocked;
3 raw material processing bulking machine due to no modulation processing will often stuck.
4. The extruded material is different, and its pressure, temperature and screw configuration requirements are different. The spiral in the extruded cavity should be adjusted accordingly, and the corresponding material should be processed according to different needs.
