measure both ball load and pulp slurry positions inside a running mill The main data are provided in terms of toe and shoulder angles Figure 6 The pulp density is an important parameter which influences the grinding efficiency In iron ore for instance a variation of 2
available m otor power in both ball mills the balls ejection from the mills is excessive when ball charge is higher than 28 Simulations were perform ed for 33 and 35 of balls and ball
Output from the secondary ball mills is fed to a common tertiary ball mill 45 by 5 m in closed circuit with cyclones Cyclone overflow is fed to the copper flotation circuit The copper flotation is a fourstage process involving rougher and three stages of cleaning There is some regrinding in another ball mill after the first flotation
Davis’ data infers a relative throughput of 23 against the open circuit at 500 circulating load where the model only predicts an increase in relative throughput to 183 When the bond baseline C1 25 E1 100 is considered Davis’ in the product of the ball mill reduces the throughput of the circuit It
In combination the throughput of the MM 500 vario is 6 times higher compared to a classic mixer mill Grinding of basalt in the MM 500 vario results in better fineness compared to classic Mixer Mills thanks to the increased frequency of 35 Hz instead of 30 Hz 50 ml jar 12 x 12 mm grinding balls
Oleg D Neikov in Handbook of NonFerrous Metal Powders 2009 Tumbling Ball Mills Tumbling ball mills or ball mills are most widely used in both wet and dry systems in batch and continuous operations and on a small and large scale Grinding elements in ball mills travel at different velocities Therefore collision force direction and kinetic energy between two or more elements vary
It’s not uncommon for a large mine to have independent planners looking after blasting primary crusher throughput secondary and ball mill grinding as well as the concentration plant A singleminded focus by any of these groups to maximize throughput may come at the expense of other units and ultimately at the expense of overall throughput
Minetomill optimisation effect of feed size on mill throughput No 48 SRK Consulting’s International Newsletter One of the most valuable aspects of blasting is the generation of very fine particles eg smaller than 12mm that will pass through the primary mills and onto the secondary ball mill circuits alleviating a common bottleneck

• Single stage crushsingle stage SAG mills and two stage crushball mill circuits are typically selected for low throughput plants 50 th where personnel costs are a large component of costs
To prevent spillage and overload the control scheme must allow the ball mill circuit to accept almost any amount of feed rate without overload At high feed rates this will compromise the grind size so the SAG mill feed rate limits must be managed to ensure the right grind size versus throughput tradeoff is
The Holt Mill was constructed in 1988 and was originally designed for a throughput of 1360 tpd Expansions in 1988 and 2001 increased the throughput to 2500 tpd and 3000 tpd respectively Surface ore storage is a total of 4900 t in three silos the Holt headframe bin 900 t and two other separate storage bins 1000 t and 3000 t
2013 saw throughput achievements of 20 Mta when feeding softer ores Crushing is performed in a single stage with a gyratory crusher The grinding circuit consists of a SAG mill and two parallel ball mills each in closed circuit with hydrocyclones The ﬂ otation circuit comprises roughers regrind and several cleaning stages
Ball Mill Liners We are regularly supplying rubber liners up to 26 ft diameter ball mills We design liners to optimize power for maximum throughput and increased liner life These liners are custom designed for your mills
Real time data from inside the mill could provide significant insight into operating a mill such that it spends more running time in an optimised state” Paul said “Sensor tags are implanted into the grinding media The tags transmit data while inflight inside the mill to an electronic receiver via a
