Roll Crusher Reduction Ratio

Double roll crushers double roll crushers reduce primarily through compression although some shear is obtained with toothed rolls rolls for these crushers come in combinations of smooth corrugated and toothed designs double roll crushers produce a finer product at lower reduction ratios and capacitiesDouble Roll Crushers McLanahan The rule of thumb for the Double Roll Crusher’s ratio of reduction is 4 1 The simplified design gives these units excellent reliability and requires very little maintenance The crushers are designed with builtin tramp relief that allows for the passing of uncrushable objects while remaining in continuous operation and returning to the initial product settingFigure 1 Double roll crusher geometry 2 1 5 Thickness of the RollFigure 1 is the geometry of a double roll crusher with a spherical particle about to enter the crushing zone of a roll crusher and is about to be nipped [4] [5] For rolls that have equal radii and length tangents drawn
