Apparatus for processing wastes from the machining of ferromagnetic materials

摘要

A method for processing wastes from the machining of ferromagnetic materials in which the wastes are mixed with a washing solution in a first tank and oil or oil-and-water emulsion adhering to the wastes is dissolved. Ferromagnetic components of the wastes are then separated from the washing solution in the first tank by means of a magnetic field, and non-magnetic components are then subjected to a washing in a following second tank. The ferromagnetic components are fed to an additional tank where they are washed again. The separated and degreased components are then filtered out of the washing liquids using suitable filtering apparatus.
