5 – Planetary rolling mill (PSW) ... What this means for you is that you cast a thick-wall tube, directly roll it into a mother tube, then cold-draw the mother tube to the final tube size on conventional drawing machines. This is the most economic route by far for small and medium production capacities.

The PSW mainly contains three conical rollers and an external ring. As shown in Fig. 2, the rollers are inclined and are located equally around the axis of the workpiece and their axes intersect that of the workpiece by an offset angle. This offset angle makes the workpiece move forward as the rollers rotate. The rollers are positioned by the ring.

This arrangement provides a feed movement as the rollers rotate around the workpiece.

Three-roll mill selection tips | Processing Magazine

A three-roll mill is used mostly for dispersion, but does some grinding as well. It uses three rollers of different speeds and directions to cause the sheer force between them to disperse and grind particles. The three-roll mill is used to disperse material within a media, which is usually some type of semi-viscous material such as cream.
