Larger diameter rolls are more advantageous than smaller diameter rolls for three main reasons: a more optimal nip angle, increased roll surface area, and reduced roll deflection. Nip angle. Larger diameter rolls reduce the nip angle between the rolls and allow the rolls to more efficiently grab the material and pull it down through the rolls.

the angle of nip 52 is less than that provided by smooth rolls 36 and 38 for the same size feed particle and for rolls of substantially equivalent diameter. This smaller angle of nip is generated through the specific interaction of the surfaces of the rolls 12 and 14. Specifically, it is the relative positioning of the alternating convex or concave surfaces and the plane …

The calculated nip angles were validated against those obtained from physical measurements during actual roll compaction. These nip angles were in agreement for various powder formulations containing plastic and brittle materials. The nip angles ranged from 4° to 12° and decreased significantly when the proportion of brittle material increased.
