Low Shear Blending and Vacuuming Drying
Ross Vertical Blenders are ideal for low shear blending of powders, pellets, granules, fibers and other solids. These blenders feature an auger that turns on its own axis and a mechanical arm that rotates the auger around the conical vessel. The mixing action in a vertical blender is far gentler than that of ribbon, paddle or other horizontal blenders, making it more suitable for delicate and abrasive applications. Spray nozzles may be installed for liquid addition and coating purposes. Vertical blenders are also commonly used in vacuum drying operations and can accommodate a wide range of feed forms including slurries, wet cakes, pastes and flowable solids. Requiring only low heat to drive off moisture or solvents, vacuum drying in a vertical blender is an excellent method for drying heat-sensitive materials without fear of thermal degradation.
