During the mixing process, the contact surface area of ​​the materials can be increased to promote chemical reactions; it can also accelerate physical changes. Commonly used mixers are divided into four categories: gas and low-viscosity liquid mixers, medium-high viscosity liquid and paste mixers, thermoplastic material mixers, and powdered and granular solid material mixers.
