The maximum particle size of a limestone sample received from a cone crusher was 2.5 cm. It was required to further crush it down to 0.5 cm in a roll crusher with smooth rolls. The friction coefficient between steel and particles was 0.25, if the rolls were set at 6.3 mm and both revolved to crush, estimate the diameter of the rolls.

Single Roll Crushers. Single Roll Crushers are typically used as primary crushers that provide a crushing ratio of up to 6:1. They crush materials such as ROM coal, mine refuse, shale, slate, gypsum, bauxite, salt, soft shale, etc., while producing minimal fines.Designed with intermeshing roll teeth and a curved crushing plate, they are extremely effective in reducing slabby feeds.
For example, a single-roll crusher, employ shear together with impact and compression. Shear crushing is normally used under following conditions. When material is somewhat friable and has relatively low silica content. For primary crushing with a reduction ratio of 6 to 1. When a relatively coarse product is desired, top size usually larger ...
