The twin-screw extruder is developed on the basis of the single-screw extruder. Due to its good feeding performance, mixing and plasticizing performance, exhaust performance, and extrusion stability, it has been widely used in extruded products. molding processing.
wear condition
Because it is easy to open, the wear degree of the threaded elements and the inner liner of the machine barrel can be found at any time, so as to carry out effective maintenance or replacement. It will not be discovered when there is a problem with the extruded product, causing unnecessary waste.
reduce manufacturing cost
When manufacturing masterbatches, it is often necessary to change the color. If a product change is necessary, the open processing area is opened within a few minutes. In addition, the mixing process can be analyzed by observing the melt profile on the entire screw. At present, when changing the color of an ordinary twin-screw extruder, a large amount of cleaning materials are required to clean the machine, which is time-consuming, power-consuming, and wastes raw materials. The split twin-screw extruder can solve this problem. When changing the color, it only takes a few minutes to quickly open the barrel for manual cleaning, so that no or less cleaning materials are used, which saves costs.
Improve labor efficiency
During equipment maintenance, the common twin-screw extruder often needs to remove the heating and cooling system first, and then pull out the screw as a whole. The split twin-screw is not used, as long as a few bolts are loosened, the handle device of the worm gear box is turned to lift the upper half of the barrel to open the whole barrel for maintenance. This not only shortens the maintenance time, but also reduces the labor intensity.
High torque, high speed
At present, the development trend of twin-screw extruders in the world is to develop in the direction of high torque, high speed, and low energy consumption. The effect of high speed is high productivity. The split twin-screw extruder belongs to this category, and its speed can reach plus 500 rpm. Therefore, it has unique advantages in processing high-viscosity and heat-sensitive materials.
Regarding the core technology of high-speed and high-torque, currently only German and Japanese manufacturers have mastered the core technology of asymmetric and symmetric high-torque gearboxes. Only Sichuan Zhongzhuang Technology Co., Ltd. is currently one of the main choices of high-end material processing manufacturers in China. It belongs to the national encouragement project for independent innovation in China.
