Zusammenfassung:	PURPOSE:To remove a surface layer containing a plating layer a trimmed waste in high efficiency by projecting grinding grains to the trimmed waste continuously cut from a surface treaded steel sheet. CONSTITUTION:In a surface treating manufacturing equipment line for galvanizing, etc., before the traveled surface treated sheet 1 is coiled in a coiling machine 2, the edge parts in sheet width direction are trimmed by a trimmer 3. The cutoff trimmed waste 4 comes into a chamber 5. Grit is injected toward the surface of the traveled trimmed waste 4 in the chamber 5 from blast nozzles 6. The trimmed waste 4 is ground to remote the surface layer of the plating waste, etc. The injected grit is carried to a grit recovering vessel 8 and separated into the grit as possible to reuse and the grit as impossible to reuse and dust. The surface treated trimmed waste 4 is coiled in a hoop coiling machine 11 and incorporated in a waste receiver 13.
