two roll mill heat flow diagrams

The opentwo-roll millconsists of parallel and horizontal rolls rotating in opposite directions. The rotation of the rolls pulls the ingredients through the nip (or bite), which is the clearance between the rolls. The remaining surface of therollis used as a means of transportation for returning the stock to the nip for further mixing. The
