Method for cleaning and preparation of oil-emulsion, particularly cooling lubricants, involves guiding oil-emulsion into filtering step through filter, where filtering step is upstream pre-cleaning step

摘要

The method involves guiding an oil-emulsion (10) into a filtering step (ll) through a filter (11). The filtering step is upstream a pre-cleaning step. The oil-emulsion is centrifuged in a centrifuge (9) for separating the solid material in pre-cleaning stage (l). An independent claim is also included for a device for cleaning and preparation of an oil-emulsion, particularly cooling lubricants.
