The comparison of the same type of parallel twin screw and parallel three screw in the color masterbatch and high filling plastic particles products making , the difference in equipment price is not big, but the difference in extrusion capacity is obvious, the three screw extrusion quantity is significantly higher than the parallel twin screw extrusion.

Advantages of parallel three screw extruder
1. High shear efficiency, good plasticizing effect

In the in-phase parallel twin-screw extruder, there is only one meshing point between the root screws, and two meshing points between the three parallel screws in the same direction. Equivalent to 2 pairs of twin screw, because of high shear efficiency, plasticizing effect is higher than flat pair.

2. Good dispersion effect
Three screws are arranged in parallel, the volume between the screws of the cylinder is larger, the material flows in the cylinder is completed between the three screws, the flow is more disorderly, chaotic, the effect of intermolecular mixing is geometrically increased, so as to form a better dispersion, titanium blue, carbon black, high filling effect is obvious.

3. More short L/D ratio
The machine has two meshing points, equivalent to double the effect of Parallel twin screw extruder, can use lower length-diameter (L/D) ratio to complete the plasticizing mixing and dispersing work of higher length-diameter ratio of flat pair.

At the same time because of the length-diameter ratio is reduced, the material stays in the barrel for a shorter time, so it is more suitable for heat sensitive and afraid of degradation of the material.
On the other hand, due to the reduction of length-diameter ratio, the equipment occupies less installation space, which is convenient for equipment setting;

4. High output capacity and low energy consumption
Three screw output is the same specification, the same power twin screw extruder 1.5 times. For the production of the same number of products, the cost of manpower, site and so on is reduced exponentially. And because its length diameter ratio is short, the host power, heaters and other power decline and energy saving.
