FREDA REBECCA SAGMILLING CIRCUIT OPTIMIZATION. parameter that affects milling performance after ore competency. A lot of operations have recognized the optimization opportunity that can be taken advantage of by manipulating the feed size distribution to improve SAG milling efficiency.
Throughput optimisation in milling circuits. Each milling circuit is unique, and as such the goals and most optimal control strategy might differ for individual cases. Process IQ is an expert in implementing control systems for SAG and Ball milling circuits, making use of advanced stabilisation and optimisation strategies developed by Mintek.
Keywords: Grinding, simulation, proce ss optimization, SAG milling. INTRODUCTION . The influence of the ore hardness variability on circuit throughput was investigated for the .
#0183;#32;Milling circuits are used in various industrial sectors to achieve desired product size distributions and product properties. The optimization and control of milling circuits is of high technological importance. Various models of mills and milling circuits are published in the literature with different precision and degree of sophistication.
A good advanced control system such as MillStar can significantly increase throughput and grinding efficiency. Additionally, the liner and lifter life can be extended and the percentage grinding media per ton of ore processed can be reduced. Controlling the feed and discharge of a
Its not all about exploration;How optimizing your milling circuit can lead to big savings Written by Matthew Gierc, Director of Marketing and Business Development at 3AG Systems Production teams have reason to feel jealous these days. It seems that their exploration colleagues get all the exciting new
Nagajyothi Virivinti, Kishalay Mitra, in Computer Aided Chemical Engineering, 2014. Multiobjective Optimization under Uncertainty. In industrial grinding process, in addition to goal of productivity maximization, other purposes of deterministic grinding circuit optimization have to satisfy the upper bound constraints on the control variables. We know that there lies a tradeoff between the
Smooth operation of a milling circuit is difficult to achieve due to: The varying nature of the feed material (size, ore hardness, etc.). The unfavorable dynamics between feeders and the weightometer. These dynamics degrade the performance of PID controllers, making feed optimisation

The higher ore BWi, the more frequent the milling circuit is Ball Mill limited (the year of 2013 was extreme one). The lower ore BWi, the milling circuit is more SAG Mill limited. an

The impact of comminution on project economics is also increasing with the observed quantum shift in the minerals industry to low grade disseminated ore reserves. OMC work closely with their clients to set optimisation goals; not only
