Ways to Improve the Working Efficiency of Twin Screw Extruder

What are the ways to improve the working efficiency of the twin-screw extruder, increase the consumption efficiency, increase the free volume of the screw groove and increase the torque and speed, the following is a detailed introduction.

Features of Twin Screw Extruder Gearbox

A new design of the gearbox transmission system of the twin-screw extruder. The output shaft transmission adopts a power split design, which doubles the torque transmitted by the output shaft, increases the carrying capacity of the whole machine by 50%, and increases the insurance coefficient by 30%......

The Structure Principle of Twin Screw Extruder

The basic mechanism of the extrusion process is simply a screw that rotates in the barrel and pushes the plastic forward. The screw structure is a slope or slope wound on the center layer, the purpose of which is to increase the pressure in order to overcome the greater resistance.

The Temperature Principle of Twin Screw Extruder

Extrudable plastics are thermoplastics, which melt when heated and solidify again when cooled. Therefore, heat is required during the extrusion process to ensure that the plastic can reach the melting temperature. So where does the heat of melting plastic come from?
