The mill product can either be finished size ready for processing or an intermediate size ready for final grinding in a rod mill ball mill or pebble mill. AG/SAG mills can accomplish the same size reduction work as two or three stages of crushing and screening a rod mill and some or all of the work of a ball mill. Because of the range of The charge motion and breakage of particles inside the mill depends on the shell lifters design while the discharge of ground particles is controlled by the grate and pulp lifters. The limitations imposed by poor grate and pulp lifter design become increasingly apparent with increasing size of ag/sag mills and their operation in closed circuit.

and size distribution water discharge rate ball throughput bearing pressure pebble throughput and toe and shoulder angles of the internal load. 2.1 SAG mill model The particles fed to the mill are ground in the milling chamber and subsequently downloaded into the discharge zone where according to a classification probability they there has been a shift of emphasis on ball mill optimization to semi-autogenous grinding (SAG) mills. In order to optimize this section the skills to accurately model and understand its underlying mechanisms are required. The literature exposed a clear lack of previous research on the influence and performance of grate/pulp lifter design in AG/SAG mill discharge.

### Outokumpu Technology s TPLTM for elimination of material

Mar 14 2007 · Similar to slurry flow-back the pebbles flowing back into the mill increase with larger pebble port or grate slot size. As the pebbles flow down and slide across the grate slots they get an equal chance to go back into the mill. Similar to slurry pool formation pebbles flow-back would increase the quantity of critical size material in the mill. Apr 24 2014 · Following implementation of these strategies the SAG mill throughput when treating the harder copper/zinc ores increased from 2 750 tph to an average of 3 600 tph and the optimization of the overall process improved energy efficiency resulting in considerably less energy consumption per ton of

### Automated condition monitoring of mill ball size

Many grates in operation are pegged by grinding media to varying degrees of severity. This paper introduces a comprehensive accurate and rapid method to measure and track the size and pegging status of each and all grate holes in situ and therefore provides tracking information on the Open Area of a SAG mill. The load in such a mill typically contains 250 000 particles larger than 6 mm allowing correct representation of more than 90 of the charge in Discrete Element Method (DEM) simulations. Most AG/SAG mills use discharge grate slots which are 15 mm or more in width. The mass in each size fraction usually decreases rapidly below grate size.

### Using DEM to model ore breakage within a pilot scale SAG mill

The load in such a mill typically contains 250 000–450 000 particles larger than 6 mm allowing correct representation of more than 90 of the charge in Discrete Element Method (DEM) simulations. Most AG/SAG mills use discharge grate slots which are 15 mm or more in width. The mass in each size fraction usually decreases rapidly below grate size.

### Converting a ball mill from overflow to grate discharge

Jun 23 2020 · Grinding mills including SAG (semi-autogenous grinding) mills and ball mills consume approximately 60-70 of the total energy cost of the entire mining operation.The mills are installed with large motors up to 20 MW which impart the required energy to successfully process many tonnes per hour and grind the rock to a powder size suitable for recovering the valuable mineral from the gangue. They are used in AG mills SAG mills all grate discharge mills (Rod and primary mills etc.) The grates are made in CrMo (FMU226 type) for AG and grate discharge mills and High-Chrome also for AG mills. The design is adapted to avoid the overthrowing of balls and to fit with the existing pulp liners.

### Using DEM To Model Ore Breakage Within A Pilot Scale Sag Mill

The load in such a mill typically contains 250 000–450 000 particles larger than 6 mm allowing correct representation of more than 90 of the charge in Discrete Element Method (DEM) simulations. Most AG/SAG mills use discharge grate slots which are 15 mm or more in width. The mass in each size fraction usually decreases rapidly below grate size. 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 re-circulation of pulp back into the mill.
