How does a light-mill work?

Again this is not correct, and could only work if the mean free path between molecular collisions were as large as the container, instead of its actual value of typically less than a millimetre. To understand why these common explanations are wrong, think first of a simpler setup in which a tube of gas is kept hot at one end and cool at the other.

Tips for maximizing tube, pipe mill efficiency (Part I)

Roll tooling suppliers vary, the ways they work the tube vary, and therefore their products vary. The yield also varies. "The surface of a roll has a continuously changing radius, so the rotational velocity of the tooling varies over the face of the tool," he said. The tube moves through the mill at just one velocity, of course.
