ELECTRICALLY CONDUCTIVE BAG FILTER FOR GRANULATION DRYER

摘要

PROBLEM TO BE SOLVED: To provide an electrically conductive filter cloth used in a granulation dryer through which a granule does not leak to the outside of a bag filter from a sewing processing part and which does not cause a powder explosion due to static electricity and the like. SOLUTION: The problems are overcome by the following process: in the bag filter 3 with electrical conductivity used in the granulation dryer, the sewing processing part is formed by sewing the filter clothes which constitute each part of the sewing processing part with a first electrically conductive fiber 34 by piling up the filter cloth with electrical conductivity, then turning up the suture parts to clockwise rotation or half clockwise rotation so that the suture parts are wound in order to hide the suture portions and sewing both sides of the hidden first electrically conductive fiber 34.
