What is the feeding system of single screw extruder?
Hello, Jinxin Rohan, Kharkiv Oblast is happy to answer your question:

Introduction of feeding system of single screw extruder

The feeding system of extruder mainly includes: feed hopper, feeding device and drying device.

1, hopper:

The hopper is above the barrel of the extruder and directly provides raw materials for the barrel. Structure of hopper: 1) a hopper for feeding the machine barrel according to the weight of raw materials; 2) Forced feeding hopper; 3) Vibrate the feed hopper.

1) a hopper for feeding barrels according to the weight of raw materials.

The hopper with this structure has a simple structure and is welded by aluminum plate or stainless steel plate. Extruder production is that the raw materials in the hopper fall into the barrel by their own weight. It is mostly used in small extruders, and the raw materials used are mostly granular.

Advantages: the structure of the hopper is very simple, the cost is low, and maintenance and repair are not needed.

Disadvantages: It can only be used when the raw materials are granular, and the feeding state in the hopper should be checked frequently to prevent the "bridging" phenomenon of raw materials from affecting the production feeding.

I hope my answer is helpful to you, and I hope it will be adopted. Thank you!
