SAG Mill Grinding Circuit Design

Semi Autogenous Design FactorsSag Mill Operation ExampleProcess Plant DescriptionSag Mill Design and SpecificationOperating Problems Since CommissioningDesign Changes and Future Operating StrategiesThe design of large mills has become increasingly more complicated as the size has increased and there is little doubt that without sophisticated design procedures such as the use of the Finite Element method the required factors of safety would make large mills prohibitively expensive.In the past the design of small mills, up to +/- 2,5 metres diameter, was carried out using empirical formulae with relatively large factors of safety. As the diameter and length of mills increased several crit...

SAG mills (semi-autogenous grinding mills) - Metso

SAG milling extends itself to many applications due to the range of mill sizes available. They 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 done by a ball mill. SAG mills are also an optimum solution for wet grinding since crushing and screening in these cases can be difficult, if not impossible. Efficiency ...

Difference Between Sag Mill vs Ball Mill - mech4study

SAG mill make use of steel balls included with some large and hard rocks for grinding. These mills utilize the balls in making the large fragments of materials broken into pieces. The ball charge of a SAG mill is about 9% to 20%.This process takes place inside the large rotating drum of SAG mill which is filled with balls partially. Interior of the drum uses the lifting plates. These plates ...

OPTIMAL SAG MILL CONTROL USING VIBRATION DIGITAL

processes vibration from three key points on the SAG mill. From these three real-time signals, it is possible to measure the volumetric material fill level in the mill and the material flow through the mill. This new information can be used to optimize the feed rate and speed of the mill for increased material throughput, reduced particle size output standard deviation, reduced specific power ...

New Used Sag Mills for Sale Semi-Autogenous Grinding ...

SAG mills are essentially autogenous mills, but utilize grinding balls to aid in grinding like in a ball mill. A SAG mill is generally used as a primary or first stage grinding solution. Attrition between grinding balls and ore particles causes grinding of finer particles. SAG mills are characterized by their large diameter and short length as compared to ball mills. SAG mills are primarily ...

Metso to Design and Supply the World’s Largest SAG Mill

He goes on to explain that “a single line grinding circuit with a 42ft (12.8m) SAG mill allows for much higher concentrator throughputs, as compared to using a dual line grinding circuit using two SAG mills. The capital cost savings using one line versus two are significant.” Will points out, however, that the new design does not compromise the traditional aspect ratio.
