The invention relates to a rare earth waste recovery device, in particular to a rapid waste drying device for rare earth waste recovery. The rapid waste drying device for rare earth waste recovery is capable of sufficiently drying rare earth waste, economically using the rare earth waste and maximizing utilization of rare earth resources. In order to solve the technical problem, the rapid waste drying device for rare earth waste recovery comprises a table, a mesh screen, a screening box, an air heater, a hot air duct, an L-shaped supporting rod, a first cylinder, a right side plate, a cover, sliding rails, a left-right moving device, sliders and the like. A first groove is formed in the middle of the top of the table, and the bottom of the first groove in the table is connected with the mesh screen in a bolted manner. The rare earth waste is screened in a layered manner by the mesh screen and the screening box, and the cover is matched with the first groove, so that the rare earth waste is dried in a closed space.
