[0002] A vertical multi-chamber continuous kneading machine is a special mixing equipment, which is mainly used for continuous mixing and processing of high-viscosity materials. The existing vertical multi-chamber continuous kneading machine is composed of a plurality of independently operated but interconnected mixing chambers. Each unit has a pair of mutually cooperating and rotating paddles to produce a strong shearing effect, so that the materials react quickly and obtain uniform mixing and stirring.
