Title:
REPROCESSING METHOD FOR SALVAGED METALLIC MATERIALS
Document Type and Number:
WIPO Patent Application WO/1996/035511
Kind Code:
A1
Abstract:
The present invention provides a reprocessing method for preventing ignition and explosion by dust generated during a reprocessing such as shearing and/or crushing of salvaged metallic materials comprising easily oxidative metals. The technical configuration of the present invention resides in a reprocessing method for salvaged metallic materials characterized in that a process for shearing and/or crushing salvaged metallic materials by a cutting machine and/or a crushing machine is carried out under either or both of the following conditions: (a) spraying by at least a two fluid type sprayer provided at a high position inside a room accommodating the cutting and grinding machines water mist of an average particle size of 10 'mu'm or less in an amount of 4-10 cc/h/m3 relative to the volume of the room; and (b) providing a two fluid type sprayer on each of the cutting and grinding machines in such a manner as to be oriented to a dust generating portion and then spraying water mist of an average particle size ranging 10-200 'mu'm in an amount of 1-100 wt.% of the generated dust volume.
