The roll forming process is the most important metal deformation technique. One of the major metal forming processes is the passage of metal through two rollers that rotate in opposite directions. Metals, when passing through rollers, decrease from the initial thickness to the predefined thickness. In the rolling process, there is not only a ...

The process parameters (roller pressure, roller gap, and mill screen size) were set following the experimental design, and roll speed, feed screw, and roller pressure were fixed at 4 rpm, 10 rpm, and 55 bar, respectively. The ribbon was formed by the force of the compression roller from the powder mixture transferred by the screw feeder.

The rolling is a process which consists of passing the metal through a gap between rollers rotating in opposite direction. This gap is smaller than the thickness of the part being worked. Therefore, the rollers compress the metal while simultaneously shifting it forward because of the friction at the roller-metal interfaces.

In this study, two-dimensional (2D) and three-dimensional FEM models for hard roller burnishing were established. The developed 2D FEM model was used to study the effects of process parameters (i.e., burnishing pressure, feed rate) on surface finish and residual stresses. The simulation results were evaluated and compared to the experimental data.

How Pharmaceutical roller Compactor Machines Work. The working principle of roller compactor machine is simple; it involves the following key processes: Basically, the idea behind dry granulation is that a fine powder that is subjected to a predetermined amount of force that transforms it into a compact sheet or solid.

The derived shear parameters, Fig. 12, show that any correlation between the FF and the roll gap width is significantly less robust than that with roll compaction force. In this instance, another derived parameter – the change in the angle of internal friction – may be related to the change in roll gap width. Download : Download full-size image
