Twin Screw Extruder High torque

1, intuitive understanding of wearing parts of the wear and tear

The twin-screw extruder is easier to open than the single-screw extruder, so that the degree of wear of the threaded element and the inner sleeve of the barrel can be found at any time, so that it can be effectively repaired or replaced. It is not found in the extrusion product problems, resulting in unnecessary waste.

2, reduce production costs

 In the case of masterbatches, it is often necessary to change the color and, if necessary, replace the product, open the open processing area in minutes, and analyze the mixing process by observing the melt profile on the entire screw. At present, ordinary twin-screw extruder in the replacement of color, you need to use a lot of clear machine for cleaning machines, both time-consuming, electricity, and waste of raw materials. The split-type twin-screw extruder can solve this problem, change the color, as long as a few minutes can quickly open the barrel, the manual cleaning, so you can use or less cleaning materials, saving costs.

3, to improve labor efficiency

 In the equipment maintenance, the ordinary twin-screw extruder often have to first heat, cooling system removed, and then the whole out of the screw. And split-type twin-screw is not used, as long as the release of a few bolts, turn the worm box handle device lift the upper part of the barrel to open the entire barrel, and then repair. This shortens the maintenance time and reduces the labor intensity.

4, high torque, high speed

At present, the world's twin-screw extruder development trend is to high torque, high speed, low energy consumption direction, high speed to bring the effect that is high productivity. Split-type twin-screw extruder that belongs to this category, its speed up to 500 r / min. So in the processing of high viscosity, heat-sensitive materials has a unique advantage.

In the high-speed, high-torque core technology, asymmetric and symmetrical high-torque gearbox is currently only Germany and Japan related manufacturers to master the core technology, the maximum speed can reach 1800 rpm, and the domestic master of this core technology, Only in Sichuan in a technology, is currently the domestic high-end materials processing manufacturers one of the main options, are independent domestic innovation to encourage the country. Split-type twin-screw extruder mainframe screw, barrel are used advanced "building blocks" design, the screw set by the core in the form of a combination of various forms of screw, the cylinder within the liner according to snail The difference between the blocks can be adjusted, and thus according to the material variety and other requirements of the process of flexible combination of the ideal form of threaded components to achieve the material transport, plasticization, refinement, cutting, exhaust, pressure and extrusion and other processes , So as to better solve the general difficult to take into account the so-called screw versatility and specificity of the contradictions, to achieve a multi-purpose machine, a machine more purpose. Another advantage of the "modular" design is that the screw and barrel elements that have worn out can be partially replaced to avoid the scrapping of the entire screw or cylinder, greatly reducing maintenance costs.
