Blend dry bulk solids with or without liquid additions quickly, uniformly and gently, with total discharge and no cross-contamination

The MUNSON® Rotary Batch Mixer delivers uniform particle distribution, uniform liquid additions, cycle times under 3 minutes, gentle product handling, the lowest energy consumption, and complete discharge with no segregation. It also cleans and sanitizes quickly and easily preventing cross-contamination.

Munson's unique, four-way mixing action gently folds, tumbles, cuts and turns the material, producing a thorough blend in only 1 to 3 minutes, while imparting minimal energy and intensity to the product.

The same blending action prevents segregation regardless of particle sizes, shapes or bulk densities, and provides an ideal fluid bed for liquid additions.

Unlike stationary mixers with agitators, MUNSON Rotary Batch Mixers produce homogeneous blends with no shear, discharge completely with no stratification and have no internal shafts or shaft seals to contact material.

Internal mixing flights direct material towards and through a stationary discharge gate which, together with multiple clean-out doors and unrestricted access to all internal surfaces, allows thorough cleaning and sanitizing in minutes.

Capacities range from 5 to 600 cu ft (142 liters to 17 m3), with equal mixing efficiency at 100% of rated capacity to as low as 15% (33% with liquid additions), providing unsurpassed flexibility.

This superior combination of attributes makes the MUNSON Rotary Batch Mixer ideal for a broad range of applications, from pharmaceutical, nutraceutical and food applications requiring absolute cleanliness, to minerals, glass and concrete blending requiring extraordinary durability.
