Abstract: A discharging device for mills, comprising: a conduit (10), structured so as to be connected to a discharge opening (3) of a mill (1); a bend (11) disposed along the conduit (10), which defines a curve of the conduit (10); a regulating device (12) associated to the bend (11) and predisposed for varying the position of the bend (11) so as to vary at least a height thereof.

Abstract: A wear-resistant lining for ball mills comprises a base (3) made of a material that is elastically deformable at the work surface (4) subjected to wear from which it is obtained, a plurality of cavities or hollows (5) suitable for accommodating bodies of hard material inside them. The presence of said bodies of hard material has the function of imparting particular wear resistance to the work surface (4) in that they are suitable for coming into contact with the grinding bodies or balls (6) made of hard material which are used in the mill as the grinding charge. The cavities or hollows (5) of at least part of said plurality are dimensioned and proportioned so that each of them is suitable for accommodating at least one of the grinding bodies or balls (6) inside it.
