離効率が得られるようになる。First, stainless steel abrasive waste with abrasive oil attached is put into the centrifuge 1 by the belt conveyor L, and while the centrifuge 1 is rotating at a low speed, the abrasive oil spout pipe 4 is lowered into the centrifuge 1. Polishing oil A heated to 60°C is applied from this spout tube to the stainless steel polishing waste in the centrifuge 1 for 2 minutes, and then the centrifuge 1 is rotated at high speed (1aoorpm).
While doing so, polishing oil A heated at 60" d/c was further applied to the stainless steel polishing debris for 1 minute, and then high-speed rotation of centrifuge 1 was continued for 5 minutes. The polishing oil is removed from the polishing oil outlet 3 of the centrifuge 1.
Some of it comes out, so some of it is sent to the polishing oil heating tank 5 and some of it is sent to the oil storage tank 11. After that, the centrifugal separator 1 is stopped, the stainless steel polishing debris is taken out through the polishing debris outlet 2 at the center of the lower part of the centrifugal separator 1, and carried out by the belt conveyor 13. Note that when the heated abrasive oil A is not to be spouted from the abrasive oil jet pipe 4, the solenoid valve 8 is closed and the solenoid valve 9 is opened. The heated abrasive oil A is circulated, the temperature of the heated abrasive oil A is prevented from decreasing, and the abrasive oil A is prepared for the next separation operation.
Due to centrifugal force, the heat of the heated abrasive oil is transferred to the stainless steel abrasive waste and the abrasive oil attached to the abrasive waste while passing through the layer of stainless steel abrasive waste in the centrifuge 1. By increasing the temperature, the viscosity of the polishing oil decreases and the separation efficiency of the polishing oil in the centrifuge increases. This results in an increase of approximately 3 to 5% in the amount of recovered oil. Especially in winter, the separation efficiency of abrasive oil is greatly improved compared to the conventional method. That is, according to the method of the present invention, an average separation efficiency can be obtained over a portion.
