Ore processing milling device

The invention belongs to the technical field of ore processing equipment, and discloses an ore processing milling device which comprises a base. A first support vertical plate is mounted on the uppersurface of the base, a support transverse plate is mounted on the top of the first support vertical plate, a U-shaped support frame is mounted on the lower surface of the support transverse plate, a first air cylinder is arranged on the inner side of the U-shaped support frame, a motor fixing seat is connected with a piston rod of the first air cylinder, a first motor is arranged on the inner sideof the motor fixing seat, and a milling cutter is connected with an output shaft of the first motor by couplings. The ore processing milling device has the advantages that a second motor can work when the end surfaces of the other side of ore need to be milled, accordingly, a first clamping block and a second clamping block can rotate, the ore further can synchronously rotate until the to-be-processed end surfaces of the
