Abstract

The invention discloses a grinding device for rare earth materials. The grinding device comprises a crushing box and supporting columns, the bottom end of the crushing box is provided with the multiple uniformly-distributed supporting columns, a feeding port is formed in the top end of the crushing box, a first crushing roller is arranged at the top of a cavity of the crushing box, one side of thefirst crushing roller is provided with a second crushing roller engaged with the first crushing roller, roller shafts at one end of the first crushing roller and one end of the second crushing rollerextend to the inner wall of the crushing box, a roller shaft at the other end of the first crushing roller penetrates the crushing box to be connected to a first gear located on one side of the crushing box, and a roller shaft at the other end of the second crushing roller penetrates the crushing box to be connected with a second gear located on one side of the crushing box. The grinding device has the beneficial effects that overall design is simple and reasonable, fine grinding is performed after crushing to enable rare earth to be ground more thoroughly, the rare earth grinding efficiencyis improved, and the crushing, grinding and screening processes are interlocked to improve the rare earth grinding quality.

Description

technical field [0001] The invention relates to the technical field of grinding, in particular to a grinding device for rare earth materials. Background technique [0002] Rare earth materials are one of the necessary raw materials for the three pillars of modern civilization (energy, information, materials). Rare earth materials include rare earth elements. Rare earth elements are the general term for 17 metal elements in the periodic table, including 15 lanthanides plus scandium and yttrium. The specificity of rare earths comes from the specific 4f electron configuration of rare earth elements. The 4f electrons are shielded by the completely filled outer shell 5s and 5p electrons. The different movement modes of 4f electrons make rare earths have optical properties different from other elements in the periodic table. , magnetism and electricity and other physical and chemical properties; and, rare earth elements have a large atomic magnetic moment, strong spin-orbit coup...
