Control Systems: Ruel Rules for Use of PID, MPC and FLC
Nov 12, 2012· The SAG mill process uses steel balls and large rocks for grinding. The load consisted of ore, steel balls and water. In addition to stabilizing the process and increasing production rates, the control system must protect the lining by ensuring the rocks fall on other rocks and not the lining. The controlled variables were density (inferential ...

Within seconds it has analysed the audio frequencies as well as taking on board power usage, mill weight and bearing pressure. It can then automatically take corrective action if needed and adjust parameters such as the mill ore feed rate, mill speed or water usage.
Geometallurgy Wikipedia
Geometallurgy relates to the practice of combining geology or geostatistics with metallurgy, or, more specifically, extractive metallurgy, to create a spatially or geologically based predictive model for mineral processing plants. It is used in the hard rock mining industry for risk management and mitigation during mineral processing plant design. It is also used, to a lesser extent, for ...

Rod Mill The grinding media in a Rod mill are long rods of particular material which grind the ore by tumbling within the mill. The grinding action is by line contact between the long rods. There is a very minimal slime production since rods tumble and spin in roughly parallel alignment and produce size reduction of coarse ores efficiently.
