SAG mill discharge as a problem. As a result Copperton asset maintenance tactics were improved, with a greater focus on the health of: • Paddle wheels (removes rocks from trommel to form pebble crusher feed); • Rubber skirts (prevents rocks from entering SAG mill discharge sump); and • Jet nozzles (returns rocks to SAG mill
of grate/pulp lifter design in AG/SAG mill discharge. The current understanding from literature lacks knowledge of mill content size distribution and its effect on discharge through the grate at various aperture sizes and radial positions. It also indicates that in order to advance the understanding in a meaningful way, a more mechanistic ...

SAG Mill Circuit Example – Gold Processing SAG mill circuit example for gold processing [image: (135-6-3)] AG/SAG Mill. AG/SAG mills are normally used to grind run-off-mine ore or primary crusher product. Wet grinding in an AG/SAG mill is accomplished in a slurry of 50 to 80 percent solids. 2D and 3D simulations of particles in a SAG Mill
A SAG mill is characterized by its large diameter and short length. It rotates, tumbling its contents violently, causing a breaking action. The mill is lined with wear resistant steel liners which are fitted with lifters to assist with raising the load. The liners are replaced as .
