MUNSON® Rotary Batch Mixers feature a stationary inlet, an opposing stationary discharge, and a rotating drum in between. Material is charged via the inlet chute while the drum is rotating.
Internal mixing flights create a gentle, four-way mixing action that tumbles, folds, cuts and turns the material.
This provides free space between particles, and causes them to recombine 288 times per minute — without the free-fall that can damage material.
The efficient flow pattern also creates ideal conditions for spraying liquid coatings, flavors, colors and impregnations onto a large area of moving material, achieving batch uniformity rapidly.
When the blend is complete, typically from 1 to 3 minutes, the discharge gate pivots into the machine and directs the material flow down the discharge spout.
Unlike mixers that spray liquid additions onto a narrow "waterfall" of moving material with the hope it will transfer to dry material, MUNSON Rotary Batch Mixers spray liquid additions onto a wide, deep bed of moving material, rapidly achieving batch uniformity to one-tenth of one percent at ratios down to 1 part per million of liquid to solids.

Internal mixing flights tumble, fold, cut and turn batch materials, while directing material toward the plug gate valve when closed, and through it when opened.
