Optimization of mill performance by using
Optimization of mill performance by using online ball and pulp measurements Soon after a stop, a mill is a dangerous place to enter for the personnel tasked with taking measurements or samples. Crash stops are difficult to handle. The mill and all feed streams should be stopped simultaneously but, often, they are stopped around about the same time. Slurry could still be pumped out of the mill ...
Optimizing your SAG mill operation
· Optimizing your SAG mill operation. Posted by Matrix on 21st March 2007 Sanjeev Latchireddi, Chief Process Engineer – Grinding Americas, Outokumpu Technology, looks at the shift from ball mills to SAG mills. Nowadays, the more successful plants are those that have adopted effective and efficient strategies to optimize their plant operation. As the 'heart of the plant' could be viewed as ...
Grinding Optimizer
Grinding is therefore considered a very beneficial target for optimization. It is critical in achieving a suitable ore feed size distribution in order to reach high grinding efficiency and throughput, especially in grinding circuits involving autogenous (AG) or semiautogenous (SAG) mills. The investment in grinding optimization pays for itself ...

Modelbased Control is suited to optimization of wellunderstood unit processes (SAG Mills, Ball Mill Circuits, Flotation Circuits, Thickeners as an example). The performance is superior to that of Modelfree systems (Expert Systems as an example) because they are capable of anticipation and thereby can predict the process response to new situations. Estimata () is a cloudbased ...

Optimization of a SAG Mill Energy System: Integrating Rock ...
· An optimization is carried out to minimize the yearly cost of energy for the operation of the SAG mill. This cost includes the energy consumption cost in /kWh and the capital cost for the PVBESS infrastructure, prorated over the life of the battery system, accounting for the discount rate through an annuity factor (Pamparana et al. 2019a, b).

· Optimizing your SAG mill operation International Mining. As a result, mines have shifted their emphasis in optimization from ball mills to SAG mills. The rock load in the mill essentially depends on ore characteristics and the discharge rate of broken particles through the discharge end. The discharge rate depends on how efficiently the discharge pump (grate and pulp lifters) operates. SAG ...

plant testing and its nature is considered in SAG mills design and optimisation. In many cases the feed size distribution is even more influential than the ore characteristics (Simkus and Dance, 1998; Kojovic, 2005), but it is not considered for the design. A notable exception is the Morrell's model (Morrell, 2008, 2009). In his approach the total specific energy of the entire AG/SAG ...
