Ross Laboratory Ribbon/Paddle Blender

The model 42NSD-1S ribbon blender is a multi-purpose unit equipped with interchangeable double ribbon and paddle agitators. With a maximum working capacity of 1 cu ft, 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% complete discharge. The unit shown is supplied with NEMA 4X controls with variable frequency drive (VFD) keypad for convenient soft start and speed control of both the main agitator and the screw auger of the discharge extruder. The blender is commonly 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 that 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).
