River Gravel Mobile Crushing production line in Kenya is composed of FTM938E69 mobile coarse crushing station, FTM935F1214L（4YK1860） medium and fine mobile crushing and screening station.
In this plant, gold ore is mainly natural gold among the ore to be processed, but it is mostly distributed in the crack of poisonous sand, pyrrhotite and quartz crystal gap, which significantly improves the processing difficulty of the gold ore. The custo

As part of its SAG mill control system Manta Controls developed the Manta Mic a robust and reliable acoustic analyser that prevents mill damage With its headquarters in Southern Australia Manta Controls develops unique advanced control systems to help optimize semiautogenous grinding SAG mills
The instrumentation installed on a SAG mill is integral to control For example the mill load and noise sensors are instruments that provide essential information for an optimized SAG mill operation Insufficient understanding of the ore characteristics and feed
SAG mill control fundamentally means managing the load in the mill by adjusting the feed rate of ore to the mill andor manipulating the rotational speed of the mill The best way to measure load is to mount the mill on load cells
The system’s software processes the signal in terms of audible intensity dB and frequencies Hz and uses three preconfigured filters to monitor the charge of the mill liner impacts and abnormal events SmartEar can operate as a standalone system or can interface with any control system
Frequent and automatic mill load adjustments SAGwise uses acoustic sensors and proprietary process control software to predict and adjust the SAG mill operation according to impacts on your mill and other main process variables The acoustic sensors ensure regular and accurate adjustments to mill loading
Jan 01 2013 · The SAG mill stability had to be improved and throughput increased The process is multivariable strongly nonlinear and before implementing this system the operators were actively manipulating many variables with varying success depending on operator experience and occurring disturbances Keywords SAG Mill SAG Control Fuzzy Logic Controller Advanced Regulatory Control 1
The required acoustic level is entered by the control room operator as a set point into the acoustic controller The acoustics of the mill charge motion is measured by
Figures 8 and 9 on the right show results from a gold plant’s SAG mill achieved with MillStar’s Segregated Ore Feed Controller combined with the Power Optimiser • The standard deviation of the mill feed control is greatly reduced • The cyclone feed is more stable allowing for consistent size separation and feed to downstream processes
Figure 86 The total volume inside the mill is given by Vm 4 D2 mL 1 2Lc L L 1 DtDm 3 1 DtDm 816 The density of the charge must account for all of the material in the mill including the media which may be steel balls in a ball mill or large lumps of ore in an autogenous mill or a mixture in a semiautogenous mill
