The invention discloses a rolling and crushing device for producing environment-friendly bricks, relates to the technical field of environment-friendly bricks, and aims to solve the problems of multiple times of filtering, screening, rolling and crushing. The rolling and crushing device specifically comprises a box body, wherein a mounting seat is mounted at the top end of the outer wall of the box body through a bolt; a first motor is mounted on the outer wall of the top end of the mounting seat through a bolt; the bottom end of the first motor is rotatably connected with a first rotating shaft through a coupler; the first rotating shaft penetrates through the mounting seat and the box body and extends into the box body; and a mounting plate is welded at the bottom end of the first rotating shaft. According to the rolling and crushing device, raw materials are squashed, crushed, mixed and filtered through the mutual matching of the first motor, the first rotating shaft, a crushing blade, a first telescopic rod, a pressing block and a first filter screen, so that the rolling and crushing efficiency of the device is improved; and the unqualified raw materials are rolled and crushedagain by a rolling disc, and the raw materials are filtered again through the mutual matching of a second telescopic rod, a bottom plate and a second filter screen, so that the raw materials are rolled and crushed more thoroughly, and the production qualified rate of the environment-friendly bricks is improved.

The invention provides a method for preparing neodymium iron boron through regenerating a waste material containing neodymium, iron and boron. The method comprises steps of (1) preprocessing the waste material; (2) correcting the components of the waste material; (3) crushing by hydrogen; (4) preparing into powder; (5) molding under a magnetic field; and (6) vacuum sintering. The method fully uses the waste material recycled in a production process, has high recovery rate of the waste material, can produce high performance product, has a simple and controllable flow, has high operability, uses no strong acid and strong base polluting the environment, is environment-friendly and energy-saving, and has high social and economic benefits.
