Advantages of split and building block twin-screw extruder
1) Wear condition
Due to the convenience of opening, the wear level of the threaded elements and the bushing in the barrel can be found at any time, so that effective maintenance or replacement can be carried out. It will not be discovered when there is a problem with the extruded product, causing unnecessary waste.
2) Reduce production costs
When making masterbatches, it is often necessary to change the color, if necessary to change the product, open the open processing area within a few minutes, and also analyze the mixing process by observing the melt profile over the entire screw. At present, when changing the color of the ordinary twin-screw extruder, it needs to use a large amount of cleaning material to clean the machine, which is time-consuming, power-consuming, and waste of raw materials. The split-type twin-screw extruder can solve this problem. When changing the color, the barrel can be quickly opened for manual cleaning in a few minutes, so that no or less cleaning material can be used, which saves costs.
3) Improve labor efficiency
During equipment maintenance, the heating and cooling systems of the common twin-screw extruder are often removed first, and then the screw is pulled out as a whole. The split twin-screw does not need, just loosen a few bolts, turn the worm gear box handle device to lift the upper half of the barrel to open the entire barrel, and then carry out maintenance. This not only shortens the maintenance time, but also reduces the labor intensity.
4) High torque and 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 500-600 rpm. Therefore, it has unique advantages in processing high-viscosity and heat-sensitive materials.
