The invention discloses a shearing-extruding-grinding activation machine. The shearing-extruding-grinding activation machine is characterized by comprising a shearing mechanism, an extruding mechanismand a grinding mechanism, wherein the shearing mechanism comprises a first motor, a first rotary shaft and a blade; the extruding mechanism comprises a second motor, a transmission part, a first roller and a second roller; the grinding mechanism comprises a second rotary shaft and a grinding block, the grinding block is fixedly sheathed on the second rotary shaft which is coaxially connected withthe first rotary shaft. The shearing-extruding-grinding activation machine disclosed by the invention has the beneficial effects that materials are processed and activated by the shearing mechanism,the extruding mechanism and the grinding mechanism in sequence, so that the effect and efficiency of activation of the materials are improved; the shearing mechanism and the grinding mechanism run synchronously to bring convenience for controlling the shearing mechanism and the grinding mechanism; the first roller and the second roller are driven to rotate oppositely by the transmission part, so that convenience is brought for gathering the materials to the middle of the extruding positions of the first roller and the second roller and further the materials can be conveniently extruded.
