Magnetic separator

Schenck wet drum magnetic separators are designed for the recovery of magnetite or ferrosilicon from dilute media. These units use high-strength radial pole (HSRP)-type permanent magnets that are sandwiched between steel pole pieces, with an active angle of 136°.

High magnetic field flux density and gradient are produced in the active separation zone. Magnetic field strength on the drum surface is approximately twice that of conventional interpole-type magnet assemblies. Due to a constant gauss profile, easy transfer of magnetics from the drum to the discharge point is achieved.

Schenck wet drum magnetic separators handle high pulp loadings and achieve maximum recovery of magnetics at high densities. The magnet/pole elements are bolted to a mild steel shaft which is machined to accept the drum bearings, drive end stub shaft and non-drive end shaft clamp block.

The drum is made from 3 mm thick stainless steel, with a 3 mm thick stainless steel wear wrap welded to the drum shell for long service life. The drum arrangement is a counter-rotation style, with extra long magnetic pick-up zone. The pulp level is fixed by a full-width adjustable weir plate, with the level automatically maintained for normal plant feed fluctuations. No spigot control is required and a direct drive assembly allows for ease of maintenance.
