CH series trough mixers are used to mix powdery or wet materials so that the main and auxiliary materials in different proportions are mixed evenly. The contact between the machine and the material is made of stainless steel. The gap between the paddle and the barrel is small, and there is no dead angle. The two ends of the mixing shaft are equipped with sealing devices to prevent the material from leaking. It is widely used in pharmaceutical, chemical, food and other industries.
