       The mixer is actually a feed mixer. Its working principle is to use mechanical force and gravity at the same time, and then mix two or more materials evenly. In addition, the surface area that can eat the material contact can be increased to promote its physical and chemical reaction.
       Our most commonly used mixers are mainly gas and low viscosity liquid mixers, medium and high viscosity liquid and paste mixers, powder and granular solid material mixers.
