Sag Mill Control It Shouldnt Be That Hard, Siemens also supplied the gearless drives for a 36ft sag mill with a rated power of 15 mw and a 26ft ball mill with 155 mw of rated power recently installed Sag And Ball Mill Controls
Get Price2016621 predictive control which drive the process to higher levels of performance and for much longer sustained periods model predictive control for sag and ball mill control real time optimization based on a model predictive controller is considered a better approach to sag and ball mill control
Agsag mills can accomplish the same size reduction work as two or three stages of crushing and screening a rod mill and some or all of the work of a ball mill because of the range of mill sizes available agsag milling can often be accomplished with fewer lines than in a conventional rod millball mill circuit a diagram of types of agsag
Aug 25 2004 we have an application in a sag mill where we have installed an electronic ear in order to listen the noise produced by the balls falling to the bottom of the mill our idea is to convert the amplitude and frequency of noise to a 420ma signal or something else in order to determine if the ball is crushing the mineral or the mill lining

Difference between sag mill and ball mill from the working principle application structure etc grind and blend solid or hard materials into smaller pieces by means of shear impact and compression
Single stage sag mills are very beneficial in reducing capex for plants with a staged throughput approach when future tonnage is to be increased the sag mill can feed downstream ball milling to boost capacity fullertraylor sagag mills range in size from 43m through 122m in diameter with powers as high as 28000 kw
Metso has experience of over 8000 grinding mills globally including manufacturing and delivering the largest sagag mills in the world our experts welcome the opportunity to assist you with circuit and circuit control design as well as startup operation and optimization of your mill
Keywords ball mills grinding circuit process control i introduction grinding in ball mills is an important technological process applied to reduce the size of particles which may have different nature and a wide diversity of physical mechanical and chemical characteristics typical examples are the various ores minerals limestone etc
With the improved control of sag mill weight the manta cube was able to increase the overall feed rate to the sag mill as shown in the feed rate histogram of figure 14

Where i work now minera san cristobal in bolivia we use sound control on both the sag and ball mills the result of this control is a 25 increase in throughput over the plant design with a 10 reduction in energy consumption the mill is more efficient the mill control manipulates the feed rate and mill speed depending on ore and liner
Sag mills are primarily used at gold copper and platinum mines where steel balls are used for the grinding the manta controls advanced control system called the sag cube automatically monitors and controls a sag mill keeping track of critical process variables impacting mill throughput
These signals along with an energy polar plot taken from the shell provide the realtime toe material flow rate and ball strike energy occurring in the mill for cement millscan is the easy to calibrate electronic ear replacement for realtime mill fill level monitoring and feeder control
