Abstract

The utility model discloses an ore grinding fineness test device for sulfur concentrate products, which comprises a scraping structure quick disassembly and assembly component, the scraping structure quick disassembly and assembly component comprises a scraping ring, a bearing plate, a transverse plate, a hydraulic expansion piece, a clamping block and a clamping groove, the top of the bearing plate is movably connected with the transverse plate, two sides of the transverse plate are fixedly connected with one end of the hydraulic expansion piece, and the other end of the hydraulic expansion piece is fixedly connected with the clamping block. The other end of the hydraulic expansion piece is fixedly connected with a clamping block, a clamping groove is formed in the scraping ring, and the clamping block is movably connected into the clamping groove. A rectangular groove and a first locking groove are formed in the scraping ring, a second locking groove is formed in the clamping block, and a locking rod is movably connected between the first locking groove and the second locking groove. The whole scraping ring can be moved out of the inner side of the ball mill body, then under the cooperation of the locking rod, the first locking groove and the second locking groove, the scraping ring can be rapidly disassembled, assembled and replaced, and compared with traditional bolt connection, the whole disassembling and assembling process is more labor-saving and simpler.
