Abstract
The quality deterioration of raw materials caused by a rise of used paper recycling rate brings about new problems that its processing plant becomes complicated and its energy consumption increases.“How should an environmentally friendly pulper be?” we approachedthe essence of pulping and have developed the high density and continuous pulping “KNEADINGPULPER” which assures an excellent recycling performance of used paper. The equipment consists of a long cylindrical tab and a multistage rotor provided in it. Raw materials supplied from its top are pulped with a high density while they are descending. They are kneaded to disperse printing ink at the lower part and continuously discharged through a screw feeder. The equipment could have following advantages, because of “Lowerkneading speed” and “No vertical circulation of raw materials”, which are not in the past.
