Abstract

PURPOSE: To separate and recover magnetic powder of specified particle diameter by moving a mixture of magnetic powder of different particle diameter in fluid and changing loci of movement of magnetic powder depending on particle diameter by applying a magnetic field.
CONSTITUTION: A mixture of magnetic powder such as metals, intermetallic compounds, oxides etc. ≤50μm in maximum particle diameter is dispersed and floated in liquid such as water, aqueous solution, alcohol etc. or gaseous Ar, He and others. This is let flow down from the port 1 of a particle size classification chamber 2, and specified speed of movement is given to the magnetic powder by spouting speed. At the same time, a magnetic field is applied to the magnetic powder by a magnet 3 and the loci of movement are changed according to particle diameter. Thus, the powder is separated according to the size, and ultrafine particles ≤1μm in diameter are collected effectively in a separated particle recovering section 5, and recovered from a discharge port 6.
