Abstract
The invention relates to a plant for separating grinding slurry originating from grinding machines into metal chips and grinding oil. According to the invention, a carrier bowl (3) in a frame (1) is filled with a divided volume of the grinding slurry (10). The carrier bowl (3) has a perforated plate (4) having an edge (5) as a floor and a sieve-like intermediate floor (8). By means of a lifting device (2), the carrier bowl (3) is moved to the effective region of an inductor plate (9) serving as a heater. The induction heat heats the ferromagnetic steel or iron particles present in the grinding slurry (10). Said heating effects a reduction in viscosity of the grinding oil in the grinding slurry (10), from which substantial portions flow downward through the openings (6) or (7). In certain cases, the effect can be improved by placing a steel plate on the free surface (16) of the grinding slurry layer (10).
