diameter of roll crusher home- solved problems mechanical operations- pair of rolls is to take a feed equivalent to spheres of cm in diameter and crush them to spheres having cm diameter. If the coefficient of friction is 0.29, what would be the diameter of rolls? angle of nip We have, 0.29. therefore, a tan-1 (0.29 nov 18, 2019 the maximum nip angle of the crusher machine is determined by the friction coefficient between the crushing material and the crushing working face. the friction angle of ore to steel plate is generally degrees, so the nip angle should not be greater than degrees. In the actual production, the nip angle of the crusher machine is far less
