Charles Ross & Son Co. offers the sanitary ribbon blender, featuring 150-grit stainless steel 316 internal and external surfaces, bottom discharge extruder, lantern rings, spray bar system with atomizing nozzles, load cells and a NEMA 4X Ross SysCon Control Panel. Ribbon blenders are commonly used for rapid blending of dry powders, granules, pellets and other solid forms, according to the company. The machines also mix paste-like materials, wet granulations and solid-liquid suspensions. Batch components are blended within a U-shaped trough via a horizontal agitator consisting of inner and outer helical ribbons. The ribbons are precisely pitched to move materials in a well-balanced axial and radial flow pattern.
