For large mills, using 125 to 140 mm (5 to 51/2 in.) feed ball size, conventional new lifterliner dimensions are around 300 to 350 mm (12 to 14 in.) overall height above the shell, with around 100 mm (4 in.) plate thickness and around 150 mm (6 in.) top width. Detailed design depends on individual mill circumstances.

Grate aperture SAG mill base power was estimated from pilot plant data at kWh/t, the basis was a SABC circuit of 8% ball charge. Maximum SAG mill power was determined by deducting the installed ball mill pinion power of kWh/t from the maximum overall circuit power of kWh/t to give kWh/t. Overall power for the comminution ...

Abstract. Although pulp lifters are an integral part of the majority of grate discharge grinding mills, the potential problems imposed due to their improper design have only come to light in recent years. Ideally, at a particular mill holdup, the discharge rate through a grateonly assembly should be matched by the capacity of the pulp lifters.

Key considerations. Numerous factors must be considered when selecting a mill liner design, including required grinding action, mill size as well as ore and grinding media characteristics, among others. These considerations will help determine the best liner material and geometry. Depending on the mill size and material being ground, a lining ...

The SAG mill in Fig. 2 is described with a dynamic nonlinear model [40]. The model is fit to the grind curve data from [29] using the stepwise procedure described in [41]. The model produces a realistic dynamic and steadystate response over a wide range of operating conditions which is suitable for testing an extremum seeking controller in ...

The design of mill liners and SAG mill discharge grates will have a large effect on how efficiently the mill operates and the circuit throughput. All models generally assume that a mill is fitted with "efficient" liners and that the grate design neither limits passage of pebbles (and pulp) nor permits recirculation of pulp back into the mill.

A vibrating screen was used to provide a mill discharge product separation at 19 mm (¾ in.). The minus 76 trail (3 in.) plus 19 mm (+¾ in.) screen oversize product, which are the "pebbles", were then crushed to essentially minus 19 mm (¾ in.) in a crushing circuit. This product was returned to the feed end of the mill.
