What Are The Structure And Working Mode Of The Double Screw Extruding Device?


According to the characteristics and working conditions of extruding plastic material for twin screw extruders, the feeding device of the twin screw extruder should be forced to measure the material. The feeding device is like an independent single screw extruder. The screw that rotates the raw material is driven by the DC motor through the output shaft of the worm gear reducer. The rotational speed and conveying volume of screw conveying material are decided by the working speed of twin screw extruders, the barrel temperature, the melt pressure of moulded products and the amount of products used for molding products, and can be adjusted at any time according to the need of products. The thread on the screw rod in the feeding device can be either a single head or a double head. Single head threads are more used.
