Rotary continuous bulk solids mixer for high-volume, low-cost applications
A new Rotary Continuous Mixer from Munson Machinery, model RCM-16X4-SS, provides high-volume, continuous mixing of bulk solid materials with or without liquid additions at low cost per unit of output.
Unlike mixers that force agitators through stationary material, the rotary continuous design features a 41 cm diameter by 122 cm long cylindrical drum with proprietary mixing flights that gently fold, tumble, cut and turn the material with little or no abrasive wear or product degradation.
An optional internal stainless steel spray line distributes liquids evenly onto a wide bed of cascading material for uniform coating, dedusting, perfuming, agglomerating, and conditioning of materials with no overspray onto drum surfaces.
Constructed of stainless steel finished to sanitary or industrial standards, the unit features a stationary inlet and outlet that can be hard piped to upstream and downstream equipment. Dust-tight seals preclude contamination of the product and plant environment, and are mounted externally, allowing rapid replacement.
The .37 kW electric motor rotates the drum from 8 to 10 RPM, producing homogeneous blends at rates of 2.4 m3/h at one minute residence time, and 1.2 m3/h at two minutes residence time typical.
The drum angle can be inclined from 0° to 2° to vary product residence time and throughput rate. A weir (dam) allows materials to build a “residence volume” of uniform blends that overflow into a discharge chute. An optional reversing weir thoroughly evacuates material at the conclusion of production runs, allowing rapid clean-out and product changeover.
The mixing drum rides on either external Nylon or alloy steel “trunnion rollers,” eliminating the need for internal shafts and seals that would otherwise require cleaning and maintenance.
Typical applications include cereals, powdered drink mixes, snack foods, pet foods, seasonings and nutraceuticals, as well as detergents, catalysts, pesticides, fertilisers, and other bulk chemicals.
The company manufacture Rotary Continuous Mixers in nine sizes from 40.6 cm in diameter and 121.9 cm long, to 182.9 cm in diameter and 731.5 cm long.
