Airmerge Blenders™

Air blending is achieved by use of a porous membrane over the entire bin bottom, 4 air plenums and a simple flow control system enable. Together they change the density of material in the fluidized bed of material to generate a gentle folding action and a near perfect blend.

Airmerge™ Blenders can be designed for batch or continuous operation to meet your requirements.

Porous fabric held with binding strips on top of removable grating panels in the Air Plenum allows access for fabric to be replaced in place.

Higher air velocities in the blending quadrant lower the bulk density causing the denser material in the three fluidized quadrants to flow into it and be displaced upward in a continuously circulating bed.

Air for fluidization and blending can be supplied from common or separate blowers as required.
