PROBLEM TO BE SOLVED: To provide a dust seal structure which reduces the frequency of maintenance by suppressing wear of a partition plate and a dust seal ring of a gyratory crusher.SOLUTION: In a gyratory crusher which has a structure for crushing a material to be crushed between a concave and a gyrating mantle 23, is formed with an oil sac 32 for filling a lubricant inside an annular mantle pad 12 supporting the rear surface of the eccentrically moving mantle 23, and is provided with an annular space 33, partitioned by a dust seal ring 15 set between a frame assembly 10 and the rear surface of the mantle 23, at the outside of the mantle pad 12, the dust seal ring 15 is fixed so as not to rotate with respect to the frame assembly 10, whereby, even if the mantle 23 gyrates, corotation of the dust seal ring 15 is prevented to suppress wear. |
