<p>The invention concerns a method for control of the properties of the remaining oil layer on magnesium or magnesium alloy particles and/ or other reactive metal particles produced from molten metal. The particles are cooled in a cooling oil with subsequent centrifuging and heating to remove remaining oil. A part of the oil layer on the particles is replaced with a lighter oil, preferably during centrifuging. The oil can be supplied as a spray. The light oil is supplied in an amount of 0.5-10 weight %. The light oil used should have a viscosity < 5 cP at 25<o>C and a flashpoint < 100<o>C. Preferably it is used oils having a viscosity < 2.5 cP and a flash point between 30 and 75<o>C. It is preferred to use dearomatized oil.</p> |
