The magnetic abrasive is used as a magnetic grinding tool, and the grinding performance directly restricts the popularization and application of the magnetic grinding technology. In the preparation process of the magnetic abrasive, the crushing process of the sintered magnetic abrasive is mostly finished manually by personnel, mainly because the current particle crushing equipment cannot finish the crushing work or the abrasive particles obtained after crushing cannot meet the technological requirements. For example, in the conventional jaw crusher, abrasive particles inevitably slip under the extrusion state during the crushing process due to the limitation of the crushing principle, and the generation of the extrusion slip motion damages the cutting edge of the grinding phase on the surface of the abrasive particles, which is just like the cutting edge of the cutter is lost, so that the grinding efficiency of the magnetic abrasive is reduced and even the grinding effect is lost during the magnetic grinding process. When the magnetic abrasive is crushed manually, the problems can be avoided to a great extent only by controlling the straight up-down movement of the hammer head, and the grinding performance of the abrasive particles is ensured. However, the manual crushing mode has low crushing efficiency and can enable personnel to suck dust generated in the crushing process. This is detrimental to the health of the staff.
