  flat twin screw extruderIt is widely used in various industries, so its use is certainly very extensive. It can also be seen in many industries. Moreover, the flat twin-screw extruder adopts side feeding technology, which improves the integrity of the material and greatly increases the output. The position and shape of the feed port also have a great influence on the feed efficiency. Under the same parameters, this can increase its feed area and increase production. Under the same inlet area, the feeding efficiency of rectangular section is higher than that of circular section. The use of lateral twin screw feeding is also based on this consideration. Of course, the equipment we are talking about today also has a strong self-cleaning ability. Since the two threaded sleeves are wound around each other, the contact portion forms a continuous space curve with a uniform gap. With the synchronous rotation of the two, the space curve also moves, forming a self-control effect between the screws. At the same time, the glue on the surface of the thread is cleaned to ensure the characteristics of no residual material.

The kneading block of the flat twin screw extruder can mix the materials inside. Increasing the number of kneading blocks of the twin-screw extruder can increase the number of kneading times and improve the quality of kneading. The increase of the pressure in the kneading zone increased the kneading resistance, increased the kneading strength, and significantly improved the kneading quality. Of course, the thread meshing of the internationally advanced co-directional double screw machine achieves equal clearance meshing, which greatly improves the self-made performance and processing capacity of the screw, and broadens its application field.

The flat twin-screw extruder has strong adaptability. For high viscosity materials, low shear rates can be processed with shallow groove screws. For materials with high shear rate or high screw speed, deep groove screw is more suitable to improve extrusion quality and output. Intuitive understanding of the wear and tear of consumables. Due to the convenience of opening, the degree of wear of the internal thread elements and bushings of the barrel can be found at any time, so as to carry out effective maintenance or replacement. When there is a problem with the extruded product, it will not be found, causing unnecessary waste. With the flat twin screw extruder can naturally reduce production costs. When making a masterbatch, it is often necessary to change the color. If you need to replace the product, please open the open processing area within a few minutes. In addition, with a flat twin screw extruder, the mixing process can be carried out by observing the melt profile over the entire screw. At present, when the color of the ordinary twin-screw extruder is changed, a large amount of cleaning material needs to be used to clean the machine, which is time-consuming and laborious, and wastes raw materials. The split twin-screw extruder can solve this problem. When changing colors, the barrel can be quickly opened for manual cleaning within a few minutes, so that no or less cleaning materials are used to save costs.
