How to choose a plastic butyl rubber discharge screw extrusion kneading machine

The discharge screw kneading machine is an industrial equipment widely used for mixing, kneading, and continuous discharge of high viscosity materials, especially suitable for production processes with high automation. This type of equipment achieves efficient and controllable discharge process through bottom screw extrusion, avoiding the limitations of space and operation caused by traditional flip cylinder discharge.

The core advantage lies in its continuous discharge capacity and high sealing performance, especially suitable for processing high viscosity and elasticity materials such as silicone rubber, sealant, hot melt adhesive, plastic, ink, carbon, etc. Compared to tilting or ball valve feeding, screw discharge can accurately control the discharge speed and seamlessly connect with subsequent production lines, improving overall production efficiency.

Main performance parameters and configuration features:

Discharge method: Using screw extrusion for discharge, the screw speed can be adjusted through frequency conversion to achieve quantitative and stable discharge, suitable for large volume or continuous production scenarios.

Applicable materials: high viscosity sealant, silicone rubber, neutral glass adhesive, hot melt adhesive, butyl rubber, battery slurry, dye, cosmetic base material, etc.

Heating method: Supports electric heating, steam heating, or thermal oil heating. Some models can achieve working temperatures up to 400 ℃ to meet high-temperature reaction requirements.

Material requirements: The material contact parts are usually made of SUS304 stainless steel, which has corrosion resistance and non rusting characteristics, ensuring product purity and equipment life.

Capacity range: Common specifications range from 5L to 3000L, and can be selected according to experimental, pilot, or industrial production needs.

Control system: equipped with manual or automatic electronic control system, supporting vacuum, pressure or atmospheric pressure operation modes. Some models integrate temperature control digital display devices for process monitoring.
