CHARLES ROSS & SON CO.: The 42NSD-1S is a multi-purpose unit equipped with interchangeable double ribbon and paddle agitators. With a maximum working capacity of one cubic foot, it 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. The unit shown is supplied with NEMA 4X controls with variable-frequency-drive keypad for convenient soft start and speed control of both the main agitator and the screw auger of the discharge extruder.
