The three-roll planetary rolling mill mainly consists of three uniform distributed conical rollers, the external ring and the mandrel as shown in Fig. 1a. The axes of the rollers have a certain inclined angle and an offset angle with the rolled copper tube, which make the copper tube generate plastic deformation and move forward as the rollers rotate.

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.
Planetary Rolling Mill PH-SG90 PSW Rolling Mill (hereafter called rolling mill) is the most important piece of equipment for casting & rolling process copper tube production. The equipment has reached international standard and obtained Chinese patent.
The parameterized modeling and localization of the rollers were implemented with the development of modeling software of the PSW mills, The model output from the software was successfully used for the finite element simulation of three-roll planetary rolling process.

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.

Abstract: Copper tube rolling process using the planetary rolling mill ha s been studied by using finite element method. This rolling is process that makes copper tube by three-roll with mannesmann method. Also, rolling process has st arted from the cold working and finished to the hot working. This rolling process h as more advantage that make reduction of process and …

The PSW mainly contains three conical rollers, an external ring and a mandrel. As shown in Fig. 3, the rollers are inclined and located equally around the axis of workpiece with their axes intersecting that of the workpiece by an offset angle. This arrangement provides a feed movement as the rollers rotate around the workpiece.
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.
