Abstract

PURPOSE:To regenerate and reutilize grindings as the title filter medium by selectively discharging a grinding fluid contained together with oil in the metal grindings. CONSTITUTION:The grindings 5 generated from the grinding of metal are pressed by a piston 2 with the use of a pressing and draining device to press out the grinding fluid and oil contained in the grindings 5. At this time, since the oil having greater wettability than the grinding fluid is adsorbed on the surface of the fiber of the grindings 5 and mostly retained, the oil is selectively left in the grindings. Accordingly, the grinding fluid can be selectively discharged by adjusting the press. The obtained grindings contg. oil is used as the filter medium for the filtration of illuminating kerosene, etc. As a result, the grindings, which have been discarded as industrial waste, can be regenerated and reutilized, and the grinding fluid and oil can also be recovered.
