<p>A device and a method for removing oil from lubricating oil-adhered fine scales produced in an iron manufacturing process and metal working process and oil-adhered metal particles produced in a metal working process for economically recycling oil-adhered particulates by performing a deoiling treatment, wherein the oil-adhered particulates and oil-adhered metal powder are mixed with water to form slurry, the slurry is sent to a centrifugal separator, the slurry is treated there by a centrifugal force of 300 times a gravity or more to separate the water and oil from the particulates and metal powder by properly setting the volume ratio of the slurry particles to the water and the relation between the centrifugal force and the particle residence time in the centrifugal separator.</p> |
