An Integrated Expert and Vision System at BHP Billiton Cannington
As part of a broad program to optimise the performance of their grinding circuit, BHP Billiton Cannington have installed an OCS Expert system together with three VisioRock online particle size analysis cameras. The main purpose of the system is to stabilise grind size and feed to the flotation circuit._x000D_
This particular application of OCS is the first installation to incorporate Metso Minerals Process Technology-Asia Pacific's (MMPT-AP) Dynamic SAG/AG Mill Model, which is able to predict numerous mill parameters that were previously unable to be measured with the existing plant instrumentation. Integrated into the logic of the control algorithm are online vision based, particle size measurements of the AG mill feed and recycle crusher product._x000D_
This paper will describe the history of the project from initiation to date, the model and OCS logic configuration, and demonstrate the significant benefits realised at Cannington mine.
