The invention discloses special phenolic plastic crushing equipment based on a mechanochemical method and a crushing method. The equipment comprises a supporting frame, a primary crushing device, a secondary crushing device, a third-stage crushing device and an automatic adjusting device, wherein the primary crushing device comprises a crushing box, a first motor, a first transmission rod, a plurality of cutter rests, a plurality of blades, a plurality of fixed cutters, a screen and a guide hopper, the secondary crushing device comprises a first roller, a second roller, a second transmission rod and a bevel gear set, and the third-stage crushing device comprises a second motor, a conical blade group and a plurality of strain sensors, and the conical blade group comprises a conical inner cutter and a conical outer cutter. According to the special phenolic plastic crushing equipment, the material is rapidly crushed, the crushing efficiency and the crushing effect are greatly improved, cross-linked chemical bonds of phenolic plastic can be broken, the molecular weight of the phenolic plastic can be reduced, cross-linked chemical bonds with weak bond energy can be broken without breaking a main chain of a polymer, the phenolic plastic has certain plasticity and chemical activity again, and regeneration of a new mixed material is facilitated.
