Effect of media size in stirred ball mill grinding of coal ...
1986-12-1 If the angle of nip is a rate-limiting factor for stirred ball mill grinding, as discussed above, it follows that the optimum Db/Dp ratio of 20:1 should remain constant regardless of ball size. In order to test this hypothesis, the breakage rates shown in Figs. 4 and 5 have been replotted as a function of the Db/Dp ratio, as shown in Fig. 9.

Roll Crushers - ScienceDirect
2016-1-1 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°.

Capacity of high-pressure grinding rolls SpringerLink
1995-5-1 Six US coals and a crystalline quartz were tested in an instrumented laboratory high-pressure grinding rolls machine equipped with 100-mm-diam. rolls. The machine was choke-fed to maximize the capacity. As expected, the specific capacity decreased with increased grinding pressure for each material tested. Among the six coals, there were significant differences in the critical angle of nip, the ...
