Charles Ross & Son Co. offers a new model in the popular line of Ross ribbon blenders. The new model, designated as the 42NSD, features a discharge screw positioned across the entire bottom of the trough and powered by a separate direct-drive system for independent speed control. The discharge screw assembly is designed with close tolerances between the screw and the trough. The screw runs forward only during the discharge cycle and in reverse during the blending cycle. This helps to eliminate dead zones and enhance mixing. The blender can discharge continuously at variable rates to match downstream packaging operations. Phone (800) 243-ROSS;
