Rami Flamer: Capacity Of Breaking Roller Mills

In every roller mill, the setup of the feeding system and the grinding system is similar to what is shown in Figure 1 (see above). The kernels (or other breaking material) fall freely through the grinding nip. They travel from between the feeding rolls through the nip of the …

Winding Better Rolls - Paper, Film & Foil Converter

This does two things. First, it orients web tension perpendicular to winding nip force, making the winding nip load independent of tension. Second, if the winding nip roller deflects or skews, a 180-deg nip wrap ensures it will be perpendicular to the entry span, reducing the likelihood of tracking or wrinkling.

Pharmahub - Resources: Roller Compactor: About

Normal stresses for roller compaction are calculated from Johanson's rolling theory. The boundary between the slip and nip regions is calculated using Johanson's criterion, i.e. gradients of stress in slip and nip regions are assumed to be equal at nip angle. Shear stresses are calculated from the normal stresses using the method of Schonert ...
