These demagnetizers produce a strong magnetic filed on the surface by use of an AC power source to demag-netize workpieces on a belt which runs over close to the surface.
• They are water-proofed and will not fail when wetted by cutting oil or cooling water. • They can be incorporated in belt type grinders or other automatic and continuous grinders. • The very strong demagnetizing force produced provides some margin on gap width on the surface to allow a belt conveyor to run over the working face.
