Want To Improve The Performance Of The Co-rotating Twin-screw Extruder? [kelongweier] (1)

The important goal of the development and development of co-rotating twin-screw extruder is how to improve production efficiency?

Usually, it can be achieved by increasing the screw speed, enhancing the plasticizing and mixing capacity, etc. Increasing the depth of the screw groove can greatly increase the conveying volume, but this is at the same screw speed, and correspondingly, the plasticizing and mixing capacity of the screw is also required to increase, which requires the screw to withstand greater of torque. At high screw speed, the residence time of the raw materials in the extruder is reduced, which may cause the raw materials to be plasticized, melted, and mixed insufficiently. Therefore, it is necessary to appropriately increase the screw length, which in turn causes the actual bearing torque and power of the twin-screw extruder to increase.

Increasing torque and speed requires careful design of the reduction distribution box. If the torque index of the equipment needs to be greatly improved, it will require a higher level of design and manufacturing of the transmission case. The higher the torque, the higher the requirements for the design, manufacturing accuracy, material strength and heat treatment of gears, output shafts, bearings and other parts in the transmission case. Demand is also higher. This is because the free volume of the threaded element needs to be increased. Under the condition that the outer diameter of the screw remains unchanged, the center distance between the two screws will be reduced, which will make the installation space of the proportioning gear and the thrust bearing less space. protrude.
