Roller press device with efficient cooling function

The invention discloses a roller press device with an efficient cooling function, and relates to the technical field of roller presses. A rotating shaft is fixedly connected with the output end of the motor, a rotating drum is arranged on the side, away from the motor, of the rotating shaft, the rotating drum is fixedly connected with the axis of the rotating shaft, an extrusion roller is fixedly connected to the end, away from the rotating shaft, of the rotating drum, a plurality of protruding blocks are evenly arranged on the outer surface of the extrusion roller, and the protruding blocks are fixedly connected with the outer surface of the extrusion roller. Materials are continuously brought into the space between the extrusion rollers by the extrusion rollers and become dense material cakes to be discharged from the lower portion of the machine under the high pressure action of the extrusion rollers, so that the grindability of the materials is improved, and in the further crushing process, the grinding e
