Abstract (en)

An abrasion or wear resistant wall structure, particularly a wall in a mill for grinding a charge including magnetic material, has at least the side subjected to abrasion formed by an abrasion resistant wall material, for example in the form of shell plates (11) and lifters (13). The wall structure has magnet means (21) so placed as to attract magnetic particles in the charge and retain said particles as an additional, automatically regenerating abrasion protective layer (23) on the side of the wall subjected to abrasion.
