Historical Models Several Mill throughput models were developed from 2001 to 2004 using the following techniques: Simple Regression Modelling - 2002 Basic multiple linear regression models were generated by fitting several months of historical mill throughput data to daily proportions of each ore domain.
• SAG Mill Limited: the overall grinding circuit is constrained by the SAG mill and the Ball Mill and Pebble Crusher circuits have spare capacity. During these periods the throughput can be as high as 6,000 tph to 7,500 tph for both grinding lines. • Ball Mill Limited: the overall grinding circuit is constrained by the Ball Mill capacity ...
mills and onto the secondary ball mill circuits, alleviating a common bottleneck. Modifying blasting practices to achieve a more suitable mill feed size – which varies according to the crushing/grinding circuit – can achieve up to a 30% increase in throughput. Following an initial benchmarking of an operation's practices,
A $73 million project to install an additional ball mill to increase grinding circuit capacity is progressing, with start-up anticipated in the third quarter of 2019. The project is anticipated to increase overall mill throughput by 5% and copper recovery by over 2% in comparison to levels .

There are 3 ball mills in our plant so we should differentiate between ball mill power and total power of ball mills which is sum of each ball mills power. By increasing throughput the mill power will increase too but it will also let us to send one of ball mills as a standby so total power seems to remain unchanged.

Replacing traditional steel cast mill liners with new lightweight composite liners is another way to increase throughput of mills. Major gold and copper operations have already started doing this in mills up to 40' Ø and seen an improvement in the slurry discharge of up to seven percent.
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 to 3% solid content in the slurry could lead to a
The sizing of ball mills and ball milling circuits from laboratory grinding tests is largely a question of applying empirical equations or factors based on accumulated experience. Different manufacturers use different methods, and it is difficult to check the validity of the sizing estimates when estimates from different sources are widely divergent.
