Description

Technical Field

[0001] The utility model relates to the field of mixer docking equipment, in particular to a docking device. Background Art

[0002] A mixer is a mechanical device that uses mechanical force and gravity to evenly mix two or more materials. During the mixing process, it can also increase the contact surface area of ​​the materials to promote chemical reaction energy. Commonly used mixers are divided into four categories: gas and low-viscosity liquid mixers, medium- and high-viscosity liquid and paste mixers, and powdered and granular solid material mixing machines.
