Pulverizing device for plate material processing

The invention discloses a pulverizing device for plate material processing. The device comprises a pulverizing barrel and a rotating shaft positioned in the pulverizing barrel, wherein the rotating shaft is driven by a driving device, a blade is mounted above the rotating shaft, the blade is arranged in a manner of tilting upwards and consists of a connecting part and a processing part, the connecting part is fixedly connected with the rotating shaft, the processing part consists of a cutting edge and a blade back, the cutting edge is thinner than the blade back, and the cutting edge is arc-shaped and rotates towards the rotating shaft. The pulverizing device for plate material processing has the advantages that the blade consists of the connecting part and the processing part, and when the processing part is worn, only the processing part needs to be changed, so that the maintenance cost is reduced; and the processing part consists of the cutting edge and the blade back, and the cutting edge is arc-shaped and rotates towards the rotating shaft, so that the pulverizing effect is great, and energy is saved.
