Nip Principle of Winding– When winding inelastic films, nip is the dominant principle of winding to control roll hardness. Web tension is controlled to optimize the slitting and spreading operations. The nip controls the roll hardness by removing the boundary layer of air following the web into the winding roll.

Oct 27, 2014· Although sometimes this set-up can still be found, most companies nowadays prefer the 2-roll-refiner due to the danger of dust explosions in sugar mills. The following 5-roll-refiner is a sophisticated machine, not very easy to operate, but essential for final product quality.
The separation by size, grade, etc. at each stage of the milling process creates many dozens of "streams" which wind their way through the mill. In a multi-story circle, the stock is repeatedly gravity-fed down through the systems and mechanically or pneumatically brought back up to the top floor.

Rolling processes 5-1 introduction: Rolling is the process of reducing the thickness or changing the cross section of a long workpiece by compressive forces applied through a set of rolls, as shown in figure (5-1). Fig. (5-1) Most rolling is carried out by hot working, called hot rolling, owing to the large amount of deformation required.

The invention of the rolling mill in Europe may be attributed to Leonardo da Vinci in his drawings. The earliest rolling mills in crude form but the same basic principles were found in Middle East and South Asia as early as 600 BCE. Earliest rolling mills were slitting mills, which were introduced from what is now Belgium to England in 1590.
The Planetary Ball Mill Pulverisette 5 allows fast and very fine grinding of hard to soft material, dry or in suspension, down to colloidal fineness. It can also be used for mixing and homogenising of emulsions and pastes. Grinding capacity of up to 8 samples per operation.

The three-roll mill has proven to be the most successful of the range of roll mills which saw extensive development in the 19th century. These included the single-roll mill and the five-roll mill. The single-roll mill works by material passing between the roll and a fixed bar pressing against the roll.
