The invention provides an organic pigment crushing device. The organic pigment crushing device comprises a crushing box, wherein a screen net is horizontally arranged in the crushing box; the internal space of the crushing box is divided into a crushing cavity and a powder collecting cavity by the screen net; a rotating shaft with crushing teeth is horizontally arranged in the crushing cavity; one end of the rotating shaft is located in the crushing cavity; the other end of the rotating shaft extends out from the side wall of the crushing box and is connected with a crushing motor driving the rotating shaft to rotate; the crushing box is placed on a supporting platform; a sliding structure is arranged between the crushing box and the supporting platform; and a vibration assembly which drives the crushing box to perform reciprocating vibration in the axial direction of the rotating shaft is arranged outside the crushing box. The organic pigment crushing device disclosed by the invention has the beneficial effects that the whole crushing box can be pushed by the vibration assembly to perform reciprocating vibration; on one hand, powder created by crushing can be sieved by the screen net and discharged, and on the other hand, materials to be crushed in the crushing cavity can be in sufficient contact with the crushing teeth on the rotating shaft due to the effect of vibration, so that the crushing effect is improved; and continuous feeding can be performed at a feed hopper, and continuous discharging can be performed at a discharge opening, so that continuous production is realized, and the production efficiency is high.
