New Ribbon Blender Model 42NSD-1S from Charles Ross & Son Co., Hauppauge, N.Y., is a multi-purpose unit equipped with interchangeable double ribbon and paddle agitators. It has a maximum working capacity of 1 ft3, suitable for lab and pilot-scale blending. This vacuum-rated blender also comes with a discharge extruder assembly installed along the bottom of the trough to enhance mixing, eliminate dead zones, and enable complete discharge.
Applications include blending dry powders, granules, pellets and other solids. The agitator’s inner and outer helical ribbons are pitched to move material axially in opposing directions, as well as radially. This combination promotes fast and thorough blending.
