Internal Mixing Single Screw Granulator: Principle and Application Analysis

The internal mixing single screw granulator is a widely used equipment in the fields of plastic, rubber, chemical and other material processing. It plays a crucial role in material preparation and processing due to its high efficiency, flexibility, and sustainability. This article will delve into the principle and application of the internal mixing single screw granulator.

1、 Working principle

The main components of an internal mixing single screw granulator include a feeding device, an internal mixing chamber, and a screw. The working principle is based on changing the physical and chemical properties of materials to achieve operations such as mixing, melting, and chemical reactions.

Specifically, the material first enters the mixing chamber through the feeding device. In the mixing chamber, materials are subjected to high temperature and high pressure, causing them to melt and mix. Subsequently, the molten material enters the screw, and the spiral shape and rotational motion of the screw cause friction and mixing with the material, while pushing the material forward. During the process of advancement, the temperature and pressure of the material gradually decrease, causing it to solidify and form granules.

2、 Application

The application range of the internal mixing single screw granulator is wide, mainly including the following aspects:

1. Plastic processing: In the field of plastic processing, equipment is mainly used to prepare various plastic particles, such as polyethylene, polypropylene, polyvinyl chloride, etc. By using different processing parameters and raw material ratios, plastic particles with different properties and uses can be produced.

2. Rubber processing: In the field of rubber processing, equipment can be used to prepare various rubber particles, such as natural rubber, synthetic rubber, etc. By adding different additives and compounding agents, rubber particles with different properties can be produced.

3. Chemical industry: In the chemical industry, equipment can be used to prepare various chemical products, such as alcohols, esters, ketones, etc. By using different reaction conditions and raw material ratios, chemical products with different molecular weights and properties can be produced.
