Impurity removing machine for mica powder production

The utility model discloses an impurity removing machine for mica powder production. The impurity removing machine comprises a machine body, a screening device, a conveying device, a grinding device and an iron powder removing device, the screening device is used for screening mica powder raw materials, and large particles are screened out; the conveying device conveys the screened mica powder out of the equipment, and the grinding device conducts secondary grinding on screened large particles; and the iron powder removing device adsorbs iron powder mixed in the mica powder. The mica powder is screened for multiple times through the screening device, so that the quality of the mica powder produced by the equipment is improved; the labor intensity of operators is reduced through the conveying device; carrying out secondary grinding on the screened large-particle mica powder through a grinding device, and storing; and the content of iron powder in the mica powder is reduced through the iron powder removing devi
