The invention discloses ball milling equipment for lithium battery material processing. The equipment comprises a bottom plate, a supporting base, a first motor, a driving gear, a damping shell, a driven gear ring, a ball milling barrel, a damping mechanism, a connection plate, a feed inlet, a support, a supporting column, a supporting foot, a stirring box and a screw rod conveyor. The screw rod conveyor comprises a second motor, a conveying barrel and a conveying screw rod arranged inside the conveying barrel, an output shaft of the second motor is fixedly connected with one end of the conveying screw rod, the output end of the screw rod conveyor penetrates through one side wall of the support to communicate with a feed inlet, the outer side of the conveying barrel is sleeved with a hollow rotating shaft, the end, close to the ball milling barrel, of the hollow rotating shaft is fixedly provided with a first bearing pedestal in a matched mode, a second bearing pedestal is fixedly installed at the other end of the hollow rotating shaft and located on the outer wall of one side of the support, a limiting groove is formed below the damping shell, and a collection box is arranged inside the limiting groove. Operation is convenient and fast, and the ball milling efficiency and the ball milling effect are improved.
