The invention discloses a fur grinding device for fur processing, and relates to the technical field of fur processing application. The fur grinding device comprises a bottom plate, a fixing platform,a fixing mechanism, a fur grinding mechanism, a separating mechanism, a first fixing plate, a second fixing plate, a connecting rod, a first cylinder, a protruding block, a bracket, a compression roller, a servo motor, a second cylinder, a transmission motor, a grinding wheel, a lead screw, a first slider, a bearing block, a telescopic rod, a fixing frame, a connecting frame, a second slider, a first sliding bar, a baffle, a chute, a chute, a second sliding bar, a shovel plate, a connecting plate and a storage box. The fur grinding device has the beneficial effects that the separating mechanism is arranged on the fur grinding mechanism, and therefore the baffle on the separating mechanism can scrape fat and residual meat attached to fur from the fur, the shovel plate movably connected with the baffle is used, the fat and the residual meat accumulated on the side wall of the baffle can be sent to the storage box for centralized collection and storage, the problem that the chippings generated by the fur grinding are difficult to be collect and process is solved, and the fur grinding efficiency is effectively improved.
