gyratory crusher failure modes | amp maintenance forums,high gmf is normal in some machines, but it may also reflect excessive looseness in gear shaft bearing fits. hope this helps, you have a tough job trying to assemble pieces of a big puzzle after the fact. a good rcfa starts immediately upon failure and the disassembly inspection is a key step..comminution - an overview | sciencedirect topics,gyratory crusher for crushing as-mined ore to ~0.2-m-diameter pieces. the crushing is done by compression of ore pieces between the eccentrically rotating spindle and the fixed crusher wall. the crushing surface on the spindle can be up to 3 m in height. crushing.regulatory and inspection manual for nonmetallic mineral,unlike the pivoted spindle gyratory, the fixed spindle gyratory has its crushing head mounted on an eccentric sleeve fitted over a fixed shaft. this produces a uniform crushing stroke from the top to the bottom of the crushing chamber. for fine crushing, the gyratory is equipped with flatter heads and converted to a cone crusher (figure 2-4)..crusher primary hydrocyclone ratio,the gyratory crusher has capacities starting from 1200 to above 5000 t/h to have a feed opening corresponding to that of a jaw crusher, the primary gyratory crusher must be much taller and heavier therefore, primary gyratories require quite a massive foundation the cone crusher is a modified gyratory crusher.
