Screw Elements for Twin Screw Extruder - Accept Customized Order
Twin screw extruder replacement parts in segment design wear-resistant material
Screw kneading block built on modular principle allows various L/D ratio of screw easily be changed to suit different material.
Modular principle design makes the screw elements can be replaced by new parts if they were wearing away during use.
1. Conveying elements
The conveying screw component is mainly a thread structure, and its function is to convey the material and give the material a certain thrust so that the material can overcome the resistance encountered in the flow channel. Conveying screw elements are currently the most popular extruder screw elements, with a strong transport function, short residence time and good self-cleaning properties.
2. Kneading elements
The main function of the kneading screw element is mixing, which is used for the distribution and dispersion of the materials. The strength and weakness of the dispersion and distribution effect are determined according to the thickness of each disk. Meantime, the larger the angle, the stronger the shear. Conversely, the smaller the angle, the weak the shear.
