How to improve the performance of twin screw extruder?

by:TENGDA     2022-09-22

The higher the torque, the higher the requirements for the design, manufacturing accuracy, material strength and heat treatment of the gears, output shafts, bearings and other parts in the transmission case. higher. Because the free volume of the threaded element needs to be increased, the center distance between the two screws will be reduced when the outer diameter of the screw remains unchanged, which will inevitably make the problem of insufficient installation space for the proportioning gear and thrust bearing more prominent.

It is also an important factor to increase the free volume of the screw groove of the twin-screw extruder. In the feeding section and devolatilization section, it is very necessary for the screw element to have a large free volume. For bulk density materials, increasing the free volume of the feeding section and the filling degree of the material in the screw groove can greatly improve the production of the extruder. ability. To increase the torque and speed, the deceleration distribution box needs to be carefully designed. In order to greatly improve the torque index of the equipment, higher requirements must be put forward on the design and manufacturing level of the transmission case.

Improving production efficiency is one of the important goals of the development of new co-rotating twin-screw extruder manufacturers, which can be achieved by increasing screw speed, enhancing plasticizing and mixing capabilities, etc. Under the same screw speed, increasing the depth of the screw groove can greatly increase the conveying capacity. Correspondingly, the plasticizing and mixing capacity of the screw is required to increase, which requires the screw to withstand a larger torque. At high screw speed, the residence time of the material in the extruder is reduced, which may cause insufficient plasticization, melting and mixing of the material.
