According to the blanking type environment-friendly papermaking raw material processing and pulping equipment based on the three-pipe channel, a motor drives a materialstirring device to rotate so that not only can raw materials for pulping be processed, but also impurities attached to the raw materials can be precipitated through a centrifugal force during pulpingto prevent the situation that environmental pollution is caused when the impurities are discharged to the outside.
