[0020] Graphite ore is added through the open end of the drum 4 on the side of the blocking ring 2, and the power of the drum 4 is turned on. The drum 4 rotates, and the crushing shaft 5 does not rotate to flatten the injected ore in the drum 4, and then the crushing shaft 5 is controlled to rotate, and the crushing shaft 5 drives the hammer 6 to rotate to crush the graphite ore. The graphite ore with a particle size larger than the aperture of the sieve hole of the drum 4 is screened out, and the unqualified particle size continues to be crushed. The hydraulic cylinder 8 is controlled to reciprocate and extend, and the extension end of the hydraulic cylinder 8 drives the bearing frame 7 to move back and forth. The bearing frame 7 drives the crushing shaft 5 to slide back and forth in the closed end of the drum 4 and the side wall of the crushing shell 1 with a clearance fit while rotating, and the crushing shaft 5 drives the hammer 6 to move back and forth. The crushing range covers the position between the two hammers 6 when fixed, realizing crushing without dead angles.
