Determination of the Nip Angle in Roller Compactors With …

The experimental method to determine nip angles requires direct measurement of the normal stress at the roll surface and the roll angular positions during compaction using sensors located on the surfaces of instrumented rolls. 6, 9, 11, 15, 16 For non-smooth rolls, however, normal stress measurement at the roll surface can be very …

Roll Crusher

The nip angle is affected by the distance between the rolls. The nip angle is defined as the angle that is tangent to the roll surface at the points of contact between the rolls and the particle. It depends on the surface characteristics of the rolls. Usually, the nip angle is between 20° and 30° but in some large roll crushers it is up to 40°.

Diameter of Roll Crusher for the Given Feed and Product Size

Angle of nip = 2 α. We have, μ = 0.29. Therefore, α = tan-1 (0.29) = 16.17 o. And we have, d = 0.5 cm; R = 1.5 cm. Substituting for the known quantities in equn.1, cos (16.17) = (r + 0.5)/(r + 1.5) 0.9604 = (r + 0.5)/(r + 1.5) r + 0.5 = 0.9604 (r + 1.5) r - 0.9604 r = 1.4406 - 0.5. r = 23.753 cm. Radius of rolls = 23.753 cm. Dia of rolls = 2 ...
