Ross has introduced a new Ribbon Blender Model, the 42NSD-1S, a multi-purpose unit equipped with interchangeable double ribbon and paddle agitators. With a maximum working capacity of one cubic foot, the 42NSD-1S is ideal for most laboratory and pilot-scale blending requirements. 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 100 percent complete discharge.

Ross Ribbon Blenders are used for blending dry powders, granules, pellets and other solid forms. The agitator’s inner and outer helical ribbons are pitched to move material axially, in opposing directions, and also radially. This combination promotes fast and thorough blending. Paddle agitators deliver gentler mixing which is more suited for shear-sensitive and friable applications. Both systems also function as paste mixers, vacuum dryers and granulators/coaters (evenly coating a liquid or very fine solid component throughout the surfaces of larger particle ingredients).
