A CIRCULAR SLOT MAGNETIZED LINER
Document Type and Number:
WIPO Patent Application WO/2008/000112
Kind Code:
A1
Abstract:
A circular slot magnetized liner includes a protective plate (1), a permanent magnet
(2), binding agent (3) and a protective layer (4). Wherein the protective plate
(1) is provided with at least one hollow slot (11) in equal interval in the axial
direction of cylindrical body. The permanent magnet (2) is inserted into the
hollow slot (11), one circle N pole of the permanent magnet (2) and one circle S
pole of the permanent magnet (2) are set alternately in the axial direction of cylindrical
body. The protective layer (4) is a circle in the axial direction of cylindrical
body and is formed on the surface of the protective plate (1). The grinding medium
(5) comes in to contact with the protective layer (4) directly. A material layer
(41) is formed in the slot of protective layer (4) of hill and dale structure. The
