RECOVERY OF GRINDING SLUDGE IN THE METALLURGICAL INDUSTRY
GRINDING SLUDGE GENERATED IN BASQUE METAL-MECHANICAL INDUSTRY AMOUNTS TO 3,700 TO 4,600 TONNES PER YEAR and is usually disposed of. However, its high metal content (over 50 %, and reaching values of over 90 % in some companies) and hazardous nature, are increasingly attracting the interest of industries and environmental administrations in minimising and recovering it. However, although magnetic filtering systems for grinding machines are included in the Basque List of Clean Technologies, no implementation is known in any company in the Basque Country.
MOSNIC-IRUDEX, a specialist in the manufacture of auxiliary elements for the machine tool industry, has led LOHIBAL, where GEARBOX BY GAMESA, SCHAEFFLER and TEKNIMAP have also participated.
