Abstract: The invention relates to a multi-layer lifter for semi-autogenous mills or SAG mills with improved durability, made up of: a base formed by a body having a rectangular cross-section, which has a first straight side wall and a second angled side wall; where an angled rectangular portion emerges from the upper half of said angled wall, in which a trapezoidal projection emerges from the lower portion of said base, to fit with the coatings or liners of the inside of the mill; a multi-laminated spring portion which is made up of a plurality of convex curved sheets and a bent straight portion that is located under the angled rectangular portion of said base; and a hollowed-out rubber body, located in the cavity formed by the base and the convex curved sheets.

Abstract: A hanging bar for supporting an anode (10) without lugs which is formed by a first lower portion of the body (11) and a second upper hanging portion (12) which comprises: two elongated splints (15) having a width similar to said second upper hanging portion (12); two plastic spacer pieces (33) connecting the ends of said two splints (15) being each one of said two plastic spacer pieces (33) formed by a base (28) from which two pillars (20) emerge, leaving between both pillars (20) a central housing zone (34), wherein on said base (28) and between said pillars (20) there is a planar surface (31) and on the inner portion of said base (28) there is an inclined surface (30), two pivoting supports (17), being each one of them housed in the central housing (34) of said two plastic spacer pieces (33), wherein said pivoting supports (17) are formed by a straight piece (43) which finishes in one of its ends in a bushing (27) in the center of which has a first hole (39) which matches second holes (38) of said pillars (
