Rotary continuous mixer for high-volume, low-cost applications
June 20, 2018
A new Rotary Continuous Mixer model CM-16X4-SS from Munson Machinery 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 (.37 kW) explosion-proof motor, the mixer consists of a 16 in. (41 cm) diameter by 48 in. (122 cm) long cylindrical drum with fixed internal mixing flights that impart a gentle, back-flow mixing action free of dead spots. Uniform distribution of particles is attained in one to two minutes typical, yielding capacities of 85 to 42 cu ft/h (2.4 to 1.2 m3/h).
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 offered by the company blend up to 10,000 cu ft/h (283 m3/h) with one minute residence time.
Other Munson mixing and blending equipment includes Rotary Batch Mixers, Ribbon/Paddle/Plow Blenders, Vee-Cone Blenders, Fluidized Bed Mixers and Variable Intensity Blenders. The company’s size reduction equipment includes Pin Mills, Rotary Lump Breakers, Screen Classifying Cutters, Rotary Knife Cutters, Hammer Mills and Shredders.
