Method and apparatus for cleaning and drying metal chips

Abstract From the Canadian patent

There is disclosed a process for producing dried and cleaned metal chips by entraining metal chips in a gas, introducing the gas into a cyclone separator having a wall heated to fluid-vaporizing temperature by combustion effected in a surrounding chamber purging fluid from said chips, exhausting hot gases and exiting dried metal chips from said separator conducting hot gaseous products of combustion from the combustion chamber to a continuous centrifuge extracting extractable fluid from starting metal chips which may be previously uncleaned and/or unwashed in, the centrifuge, entraining the chips in the hot gaseous products of combustion introduced into the centrifuge and conducting the …
