D-type hydraulic pulper main characteristic is to use the “D” type tub, energy-saving fu, rotor, inside and outside double blade can energy saving 25%, waste paper and the rotor contact more quickly, more often, and compared with the traditional hydraulic pulper, the time of waste paper pulp, without any increase in power and volume increase production capacity. The rotor of the D type hydraulic pulper and the slurry disk are higher than the bottom plane of the pulping machine, forming a low-pressure flow area around the rotor, so that the thick impurities in the process of the crushing process enter the sink well. This machine has vertical and horizontal two kinds.
