The invention relates to a device and a method for separating grinding oil from grinding slurry. The device has an agitation container (1) having an agitator (3) which is movable upward and downward in said container. Furthermore, grinding slurry comprising oil is introduced into the agitation container (1) via a supply line (4). In addition, there is a supply and return line (6) for a separating agent which is supplied into the agitation container (1) and by means of which the grinding oil can be separated from the grinding slurry. After being cleansed of grinding oil, the grinding slurry is delivered from the agitation container (1) into a separate receiving container (21) via a discharge line (8). A ring plate (9) is provided in the agitation container (1), which can be displaced in the height direction according to the respective functions of the agitation container. Said ring plate (9) is guided in a sealed, gliding manner on an agitator guide pipe (2) on one side and on the inside (11) of the wall of the agitation container (1) on the other side and has a passage (12) for discharging the grinding oil (25) discharged on the separating agent (24). In order to deliver separating agent (24) out of the agitation container (1), a discharge line (8) is provided at the lowest point of the agitation container (1) for delivering oil-cleansed grinding slurry (23). A homogenized mixture of separating agent (24) and grinding slurry is achieved by the agitator (3) such that the grinding oil (25) can be reliably separated essentially from every grinding particle of the grinding slurry. After the agitator (3) stops, the separated grinding oil (25) can float on the separating agent (24) and be removed from there. |
