Ross has announced the completion of a new model in its line of ribbon blenders. The new model has been designated the 42NSD.
Ribbon blenders are often used for dry and fluid blending applications in the chemical, food, pharmaceutical, and plastics industries. Upon completion of the blending cycle, discharge has traditionally been routed through a valve mounted in the bottom center of the U-shaped trough. The 42NSD’s new design features a discharge screw positioned across the entire length of the trough. The screw is powered by a separate direct drive system for independent speed control.
The discharge/extruder assembly is designed with very close tolerances between the screw and the trough. This provides a positive flow and discharge force that enables the use of an extrusion die when the blender is being used for pasty materials. The screw runs forward during the discharge cycle and in reverse towards the driven end during the blending cycle.
