The drying mixer uses double-layer stirring blades to make the material roll up and dow ninside and out, forming effective convective mixing. Mainly used for plastic color mixing, itutilizes the high-speed operation of the feeding blade to quickly evaporate plastic particles (or resin powder) through the exhaust pipe, resulting in dry rolling, collision,and heat generation. This not only makes the material wet during color mixing, but also achieves ideal drying effect.
