Abstract
A magnetic separation apparatus (10) for separating magnetic materials from non-magnetic materials in a material flow comprising self cleaning magnetic separators (15) comprising: a cylinder (20) having a first end closer to a material flow than its second end in use, a piston (25) slidingly mounted within the cylinder (20), and a magnetic shaft (30) extending from the piston (25), the piston (25) and cylinder (20) adapted to move the magnetic shaft (30) between an extended position (31) and a retracted position (32), such that in the extended position (32), at least a sleeveless portion of an outer surface of the magnetic shaft (30) is exposed to the material flow and in the retracted position the magnetic portion is retracted substantially or wholly within the cylinder (20), the apparatus including a protected shaft wiper (120) and shaft seal (125) within the first end of the cylinder (20) for removing extracted magnetics.
