磁选是利用物料在磁场中的不同行为。物料分为强磁性物料、弱磁性物料和非磁性物料。本文描述各制造厂商生产的用于选别弱磁性物料的各种强磁场磁选机。这类磁选机的特点是它的磁场,由一个平面磁极发出的磁通经过一个空气隙高度集中在一个或几个齿极上。这类磁选机用于干选或湿选过程,处理的物料一般不大于5毫米。
Magnetic separation is the use of materials in the magnetic field of different behavior. Material is divided into ferromagnetic materials, weak magnetic materials and non-magnetic materials. This article describes the various strong magnetic field separators produced by various manufacturers for the selection of weak magnetic materials. Magnetic separator of this type is characterized by its magnetic field, the magnetic flux emitted by a planar magnetic pole through an air gap is highly concentrated in one or several teeth. This type of magnetic separator for dry or wet election process, the processing of materials is generally not more than 5 mm.
