Three dimensional mixer is a machine that uses mechanical force and gravity to evenly mix two or more kinds of materials. Hybrid machinery is widely used in various industries and daily life. The three-dimensional mixer can mix a variety of materials into a uniform mixture, such as cement, sand, crushed stone and water into wet concrete materials; It can also increase the material contact surface area to promote chemical reaction; It can also accelerate physical changes, for example, adding granular solute to the solvent can accelerate dissolution and mixing through the action of mixing machinery. The commonly used three-dimensional mixers are divided into four categories: gas and low viscosity liquid mixers, medium and high viscosity liquid and paste mixing machines, thermoplastic material mixers, and powder and granular solid material mixing machines.
