The screw rod of color master granulator is of building block type.According to different materials, the screw combination can be adjusted to improve the quality of master batch.The operation of color master granulator is simple, efficient and energy-saving.The production material quality is stable, the color is gorgeous, the particle is even;The screw rod has strong self-cleaning ability and is convenient and fast to change color;

The machines are usually fed with premixed granules of the host polymer and the master batch. The final mixing then gets done in the screw and extrusion part of the machine. This is sometimes prone to adverse effects, e.g. separation of the masterbatch and the base material in the machine's hopper. The masterbatch can be also added directly to the machine's screw, as a free-flowing solid or in case of a liquid masterbatch by e.g. a peristaltic pump. Such use of liquid masterbatches allows highly accurate dosing and quick change of color between machine runs.
