Multi-Purpose Ribbon Blender
The new model 42NSD-1S Ribbon Blender from Charles Ross & Son is a multi-purpose unit equipped with interchangeable double ribbon and paddle agitators. With a maximum working capacity of 1 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, according to the manufacturer. 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.
