In the plastic industry, it is used for mixing plastic particles to ensure uniform mixing of different plastics. High speed motors are used to prevent material dissolution, volatilization, or deterioration during the mixing process. A mixer, also known as a color mixing machine, is a machine that uses the vortex type high-speed operation of the feeding blades to cause plastic particles (or resin powder) to roll, collide, rub, and heat at high speed, allowing the material to quickly evaporate water from the exhaust pipe while mixing, achieving the purpose of drying. It is mostly used in plastic products. It is divided into vertical mixer, horizontal mixer, drum mixer, and drying mixer.
