Abstract: A treaded lifter bar (1) for grinding mill is provided with a plurality of flexible treads (2) positioned over the core rubber matrix forming its main rubber surface. Treads (2) have a zig-zag configuration with higher rubber content in their wear zone to increase the surface area and reduce the wearing lifter bar (1). The treads (2) primarily absorb the impact force (3a) of slurry (4) and dissipate the heat generated due to impact. The slurry (4) is deposited on top of the treads (2) thus protecting the treads (2) from direct contact with the slurry (4) to ensure less wear. The zig-zag configuration of the top wearing treads (2) of the treaded lifter provides increased wear volume.

Abstract: An improved trommel assembly (1) for screening different particles, comprising a plurality of modular units (2) detachably attached to one another, each modular unit having a flange (3) adapted to firmly attach with one or more corresponding flanges (3) of one or more corresponding modular units (2).

Abstract: The trommel assembly (1) with a spiral assembly having a decaying spiral pitch (3) comprises rotating drum structure with the decaying spiral assembly (2) and screen panels (6) made of polymeric material or rubber compounds. The pitch (3) is at a maximum at the inlet and at a minimum at the outlet providing increased screening efficiency. Maximum pitch produces low media height with increased inlet velocity and minimum pitch increases media height. The spiral (2) is of single start, double start or multi start configuration. The pitch (3) decreases along the trommel such that screening efficiency is improved without affecting the retention time.
