Nanjing twin-screw extruder manufacturer information: Twin-screw extruder has the characteristics of high efficiency, high quality and high output. It is widely used in the processing of a variety of materials, such as: dense color masterbatch, thermosetting plastic mixing and extrusion , Hot melt adhesive, glass fiber reinforced, etc. From the point of view of the principle of motion, the twin-screw extruder can be divided into non-meshing type, counter-rotating meshing and co-rotating meshing.

Today, Tengda Machinery, a manufacturer of twin-screw extruders in Nanjing, will give you a detailed introduction to their work characteristics.

1. Non-intermeshing twin-screw extruder. The center distance between its two screws must be greater than the sum of the radii of the two screws, only in this way can it work normally.

2. Counter-intermeshing twin-screw extruder. The twin-screw extruder can carry forward conveying, and the gap between its two screw groove screws is very small than the gap in the same direction.

3. Co-rotating intermeshing extruder. There are two types of twin-screw extruders, high-speed and low-speed. The high-speed is mainly used for processing special polymers; the low-speed is mainly used for profile extrusion. The high-speed co-rotating extruder has a closely matched spiral shape. The screw can be designed to have a certain screw gap, so that the screw has a closed self-cleaning effect. This twin-screw extruder is also called a compact self-cleaning co-rotating twin-screw extruder; the low-speed extruder has a compact The geometry of the intermeshing screw, in which the shape of the ridge of one screw and the shape of the other screw closely match, which is the so-called conjugate screw shape.

Today’s twin-screw extruders are developing in the direction of low energy consumption, high speed and high torque. It greatly improves the production efficiency of enterprises. It is used in the processing of heat-sensitive materials and high-viscosity materials.
