A molding sand reclamation method and reclamation system effectively separates magnetically attracted matter from molding sand. The molding sand reclamation method includes removing metal powder and metal pieces by magnetic separation with a first magnetic flux density and removing magnetically attracted matter by magnetic separation with a second magnetic flux density higher than the first magnetic flux density from molding sand separated from a casting by shot blasting, and removing by dry mechanical reclamation, from the molding sand, substances including carbonized matter adhered to the surface of the molding sand.

The present invention relates to a CLC and operation method thereof equipped with a loop seal separator using magnetic oxygen carrier particles and a magnetic separator. And more particularly, the present invention relates to a loop seal separator using magnetic oxygen carrier particles and a magnetic separator, wherein the loop seal separator comprises a duct into which the ash and magnetic oxygen carrier particles, discharged from a reducer, flow; a magnetic separator to separate the ash from the magnetic oxygen carrier particles, flowing into the duct, by magnetic material; an ash discharge pipe to discharge the ash, separated by the magnetic separator; and an oxygen-carrier-particle discharge pipe to encourage the magnetic oxygen carrier particles, separated by the magnetic separator, to flow into an oxidizer.

An apparatus for producing pozzolanic material from waste includes a glass separator unit to remove glass material from the waste and a size reduction unit downstream the glass separator unit. The glass separator unit includes an outer member and a wound member positioned within the outer member and defining an open central bore. The outer member and the open central bore define respective longitudinal axes extending on a common plane that are disposed at an angle relative to a horizontal reference plane, with the inlet higher than the outlet. Non-glass/non-ceramic material is output through the open outlet end of outer member utilizing a flow of separation fluid. The glass/ceramic material is output to the size reduction unit through the open inlet end of the outer member utilizing the rotating wound member of the glass separator unit.

A method of creating a zone of high-gradient magnetic field in a Kittel open domain structure is disclosed. The method is based on a magnetic system of an open domain structure type and is embodied in the form of two substantially rectangular constant magnets which are mated by the side faces thereof, whose magnetic field polarities are oppositely directed and the magnetic anisotropy is greater than the magnetic induction of the materials thereof. The magnets are mounted on a common base comprising a plate which is made of a non-retentive material and mates with the lower faces of the magnets, thin plates which are made of a non-retentive material, are placed on the top faces of the magnets and forms a gap arranged above the top edges of the magnets mated faces. A nonmagnetic substrate for separated material is located above the gap.
