Abstract
A magnetic drum separator comprises a drum rotatable about an axis, the drum comprising an internal chamber and an opening at an end of the drum providing access into the internal chamber. The magnetic drum separator also comprises an inlet for supplying a liquid or granular substance into the internal chamber through the opening, a magnet outside of the drum for attracting magnetic material in the liquid or granular substance towards an internal sidewall of the internal chamber, a collection device for recovering magnetic material attracted to the internal sidewall and an annular seal member attached to the end of the drum that rotates with the drum in use. A baffle that bears against the annular seal member partially seals the opening. A plurality of cavities formed in the annular seal member receive fluid leaking into a boundary between the annular seal member and the baffle.
