Rotary continuous mixer

The CM-16X4-SS model provides continuous, high-capacity mixing of bulk materials with or without liquid additions at low cost per volume of output. Powered by a half-horsepower motor, the mixer consists of a 16 in. diameter by 48 in. long cylindrical drum with fixed internal mixing flights that impart a back-flow mixing action free of dead spots. Uniform distribution of particles is typically attained in one to two minutes, equating to capacities of 85 to 42 cu. ft./hour.

Heavy-gauge mixing flights of the stainless-steel machine impart a four-way mixing action that maximizes uniformity, while minimizing degradation and abrasive wear. Optional stainless steel piping with spray nozzles distributes liquids evenly onto cascading material without overspray onto drum surfaces, according to the company. The stationary inlet and outlet at opposite ends of the drum can be hard piped to upstream and downstream equipment. Dust is contained by outboard seals designed for rapid replacement.

The mixing drum rotates on heavy-duty hardened steel or Nylon “trunnion rollers” external to the mixing cylinder, eliminating the maintenance, product contamination and cleaning difficulty associated with internal shaft seals that contact material. An optional “reversing weir” at the mixer’s outlet allows virtually complete discharge of blended material at the end of a product run, facilitating rapid changeover. On this and other small models, the internals can be completely removed for cleaning or inspection. Larger models blend up to 10,000 cu. ft./hour with one-minute residence time. — Munson Machinery Co., Utica, N.Y., 800/944-6644;
