Ordinary twin-screw extruders require a large amount of cleaning material

Ordinary twin-screw extruders require a large amount of cleaning material to clean the machine when changing colors, which is time consuming, costly, and wastes raw materials.

The split-type twin-screw extruder solves this problem. When the color is changed, the barrel can be quickly opened and manually cleaned in a few minutes, so that the cleaning material can be used or not, which saves costs.
Conventional twin-screw extruders often have to remove the heating and cooling system before extracting the screw as a whole.

The split-type twin-screw extruder is not used. Just loosen a few bolts and turn the worm gear handle to raise the upper half of the barrel to open the entire barrel and then perform maintenance. This reduces maintenance time and labor intensity.

At present, the development trend of twin-screw extruders in the world is to develop toward high torque, high speed and low energy consumption. The effect of high speed is high productivity. The split-type twin-screw extruder belongs to this category and its speed can be increased by 500 rpm. Therefore, it has unique advantages in processing high viscosity and heat sensitive materials.

The water-cooled extruder barrel is actually a heat exchanger. Like all heat exchangers, the water channel is prone to fouling and deteriorates. Many operators have noticed that the cooling performance of a new extruder is much better than that of a three or four year extruder. The old machine has a layer of scale attached to the inner surface of the waterway, which affects heat transfer efficiency. Cleaning the barrel with a certain concentration of acid can clean the scale and maintain a good heat transfer effect.
