The internal flow baffles are optimized for more efficient blending in a larger variety of industrial applications. Thus reduces the likelihood of bridging or rat-holing with many materials. The compact and simple Zone Blender, with no moving parts, uses a combination of mass flow (first in – first out) and funnel flow (last in – last out) to help homogenize the blend and reduce the effect of segregation in re-circulating, batch or continuous systems, or any application requiring the blending of materials. It can be used for mixtures of many ingredients and is frequently employed by compounders, recyclers, food industry processors and others who require a uniform blend of materials at the use point. The Zone Blender is suitable for 1.2 m [4 ft] to 3.6 m [12 ft] diameter silos or hoppers.
