SAG mill throughput as a function of grate open area As shown in Figure 2 the grate open area has a strong effect on Sossego SAG mill throughput The nominal capacity of the circuit should be achieved with a combination of 135% ball charge and 108% open area with 3 and 35 inch apertur
crusher, Table 3. The interior of the mill is illustrated in Figure 1, showing the length and filling of the mill, and low lifters on top of standard AMS grid type liners. The detail shows sections of the discharge grate (18mm round holes extending to near the centre of the grate), and pebble ports (75mm round holes).
Aug 01, 2014· AG and SAG mills of 12–23 MW power draw are at the forefront of size reduction for mineral extraction in most of the mining operations around the world. The pulp discharge mechanism, consisting of a grate and pulp lifter arrangement, is an integral component of these mills. The grate retains oversize particles in the mill charge.
Optimized dischargeend serviceability is particularly important for an openended mill as the grate design is the primary mechanism to control the slurry pool level. Therefore, the ability to easily iterate grate configurations is imperative for process performance optimization, especially during early operation or when there are significant ...
A set of experimental test work has been carried out in a continuous pilot ball mill of X m (diameter X length) at different mill speeds, percent solids and discharge mechanism. The results of study on material flow through a grate discharge tumbling mill verses an overflow tumbling mill are presented to emphasize the effect of ...
The literature exposed a clear lack of previous research on the influence and performance 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 .

The effect of liner wear on SAG mill performance has gained much attention in recent years. It is commonly observed that the three key performance criteria of SAG milling; throughput, power and product size all improve as the liner wears. The increase in throughput is generally ascribed to the increase in the grate apertures and...
This paper differentiates scrubber and AG mill modelling in a similar way that overflow ball mills and grate discharge ball mills are analysed. Smaller scrubbers (600 kW) are suited to small scale ...
The discharge grates of the SAG mill were identified as a key component in the SABC circuit, and their design is a crucial factor in the mill''s performance [17,18,19,20,21]. The initial design of the grate section caused a serious accumulation of pebbles within the SAG mill which contributed to a decreased grinding efficiency.

Sag Mill Troubleshooting Guide. Autogenous and Semiautogenous mills . AG/SAG mills are often the optimum solution for wet grinding (achieved in a slurry 50 to 80 percent solids) AG/SAG mills can accomplish the same size reduction work as two or stages of crushing and screening, a rod mill, and some or all of the work done by a ball mill.
Overflow VS Grate Discharge Ball or Mill Why Retrofit. · The cost of a ball mill conversion from overflow to grate discharge is ''fairly'' affordable at 65,000 for a 13′ x 15′ mill. This is only for the discharge head, grates and pulp filters (rubber).
carry the slurry from the discharge grates to the discharge trommel for exit the mill. The existing from radial pulp lifters were replaced with a proprietary design known as the Turbo Pulp Lifter or TPL™. Figure 2 Crash stop of SAG mill showing pooling . The mill grate discharge included square pebble ports which hadvery limited open area ...

Ball Motion inside a SAG Mill . Ball Motion inside a Ball Mill. To a more significant degree than in other comminution devices, liner design and configuration can have a substantial effect on mill performance. In general terms, lifter spacing and angle, grate open area and aperture size, and pulp lifter design and capacity must be considered.

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.
Apr 01, 2013· Decrease in grate open area if discharge grates are relined. 4. Suitable but overdesign of new liners causing a decrease in breakage. 5. Unsuitable design of new liners for the mill in question. 6. Inefficient adjustment of operational parameters during early liner life cycle stage.
