Plow mixers are a type of industrial mixer that uses a horizontal, cylindrical drum and a set of plows mounted on a shaft. Plow mixers are designed to mix powders and solids that are free-flowing, as well as those that have some degree of stickiness or agglomeration. The plows are designed to move the material from the center of the drum to the edges, and from the edges to the center, creating a rolling action that ensures thorough mixing. Plow mixers are a low shearing type of mixer and with the option of choppers can be more aggressive if needed.
