Rare earth raw material surface treatment device for cerium oxide production

The invention relates to the technical field of rare earth raw material processing, in particular to a rare earth raw material surface treatment device for cerium oxide production. The rare earth raw material surface treatment device comprises a discharging barrel, the discharging barrel is in a square barrel shape, a crushing roller and bearing assemblies are arranged in an inner cavity of the discharging barrel, and two symmetrically-distributed bearing assemblies are arranged around the crushing roller; the bearing assemblies are fixed on the shell of the discharging barrel, according to the structural design, the crushing roller is effectively protected, the crushing roller rotates to crush rare earth blocks, and if the crushing roller is clamped by the rare earth blocks and the clamping pressure is small, rotation of the crushing roller is interrupted, and the crushing roller recovers to rotate after a short time, so that the rigid clamping influence is effectively avoided. And if the crushing roller is
