PURPOSE: A device for crushing sintered ore with high engagement of crusher blades is provided to prevent crushed ore pieces from getting in clearance between the blades, and thus preventing wear of the blades and driving shaft due to the pieces, resulting in an extension in the life span of the device. CONSTITUTION: The crushing device comprises: a driving shaft(20) adapted to be driven by a motor and rotatably supported by a bearing block(10); a crusher blade unit(40) having a plurality of blades; an outer drum(50) fastened to the driving shaft; an inner drum(70) which is inserted into outer drum and supported by a fastening unit(60); and elastic members(80) supported between the outer and inner drums and adapted to compensate the generation of a clearance between the blades.
