TREATING METHOD FOR GROUND METAL SLUDGE AND METAL SLUDGE GRAINING DEVICE

摘要

PROBLEM TO BE SOLVED: To prevent the shelf hanging phenomenon of a sludge expected to be generated in a stay hopper. ;SOLUTION: A sludge grain 6 is made by compressing while cutting an deoiled sludge 5 by a metal sludge graining device 20 and thrown in a stay hopper 8 through a conveyer 7. Thereby, when the deoiled sludge is compressed, the density of its surface is increased and its precipitation is expedited and the fuzzing of a fiber can be restrained. As the fuzzing of this fiber, which performs a role of a hand for the mutual bonding of a lump, is restrained, the anxiety of the mutual union of the lump (grain) is eliminated. Then, a smooth treatment can be continued without the shelf hanging phenomenon in a stay hopper.;COPYRIGHT: (C)1998,JPO
