Modeling SAG Mill Performance Prior to embarking on the development of any type of high level control strategy a series of tests is required to determine the nature of the relationships between SAG mill throughput load as measured by bearing pressure and measurements inside the mill and power draw amps andor kilowatts

SAG mill vs Ball mill Crushing ratio The biggest characteristic of the sag mill is that the crushing ratio is large The particle size of the materials to be ground is 300 400mm sometimes even larger and the minimum particle size of the materials to be discharged can reach 01 mm

Bearing pressure controller Mill water addition automatic PI control – operator or remote setpoint from mill Density controller However during the production rampup it was quickly evident that despite much effort the cascade PI bearing pressure control was poor and resulted in large swings in both feed and mill charge Figure 2

Modelling SAG milling power and specific energy consumption including the feed percentage of intermediate size particles In these circuits the SAG mill is the largest energy consumer In many engineering rectly measured with bearing pressure measurements it was decided to discard it as an input variable The main reason is that

Automated SAG Mill Speed Control Using Additional vibration sensors were also positioned at fixed points on the inlet and discharge ends of the mill to yield two realtime volumetric fill levels along with another fill level measurement taken ie mill power and bearing pressure 4

On a 11’6” x 22’0” Ball Mill the trunnion bearing lubrication system provides continuous low pressure flood oil for cooling and lubrication of the bearings and high pressure oil for hydrostatic lift of the feed and discharge trunnions during startup of the mill System monitors including pressure switches and flow monitors are provided along with temperature sensors that monitor

The modeling and simulation of semiautogenous SAG mills have been widely used in the design and optimization of mill performance in terms of its power draw processing capacity and product size distribution However these models are solved under steady approximation and do not provide any information on mill charge distribution in real time

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

Detecting the onset of overloading in a semiautogenous grinding SAG mill is a challenging task for operators to perform due to the complex and nonlinear nature of an overload

It is the sound of rising costs by the hour both from the downtime itself and from maintenance costs Optimising the capacity of your SAG mill is crucial to avoiding downtime and liner wear and damage With variances in mill ore feed rate mill speed and slurry density critical impacts can occur in your SAG mill

Grinding Mill Charge Detection Sensors The throughput and efficiency of a SAG mill depends on the volumetric load An overloaded mill has reduced coarse ore breakage as the cascading balls and rock cannot drop far enough reducing kinetic energy for breakage

Increasing the bearing pressure led to increase the mill speed in order to increase breakage and discharge rate After some time as the bearing pressure was increasing continuously mill feed rate decreased and water flow rate adjusts itself with the feed rate in order to keep SAG mill load solid percent within acceptable limits

GrindingExpert automatically adjust feed rate mill speed and water addition to reduce upsets eliminate grindouts and increase tonnage in SAG ball mills We constantly maintain desired operating conditions by monitoring bearing pressure power recycle pebbles mill density and mill acoustics
