Autogenous mills, semiautogenous mills and ball mills for wet . SAG and ball mill for gold ore grinding. One of three SAG mills with m diameter and 2 x 4000 kW drive power.
Mill power Usually, plant operators use mill power readings as an indicator of ball filling degree and, often, try to keep it at the maximum level. It is well known that the mill absorbed power depends on operating parameters other than ball level, such as pulp density and liner configuration. Figure 2 shows that there is no linear relation between

easy and the power split between SAG and ball mill a matter of choice based on known facts by using the SAG Power Index Test and the Bond Work Index power calculation for the production of fines. The objective of the SAG Power Index Test is to find how long it takes to grind a sample from 80% passing ½ inch to 80% passing 10 mesh.

intermediate size ready for final grinding in a ball mill, pebble mill, or VERTIMILLTM. Wet grinding is accomplished in a slurry of 50 to 80 percent solids. AG/SAG 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.
Traditionally, many engineers have approached SAG circuit design as a division of the total power between the SAG circuit and ballmill circuit, often at an arbitrary power split. While this approach may result in a successful design, it ignores the critical decision of determining the correct power split between the SAG and ballmill circuits.
Every mining operation has a unique grinding process. has experience of over 8,000 grinding mills globally, including manufacturing and delivering the largest SAG/AG 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.

SAG mills mimic the same shortcoming. It follows that in order to obtain the specifi c energy (SE) to achieve a certain transfer size, based on the 80 per cent passing value, an ineffi ciency factor must be applied to the SE of single stage ball mills, rod mills or AG/SAG mills when calculating power according to the Bond Third Theory method.

Outotec® MH Series Grinding Mills offer a cost effective, and easy to operate and maintain grinding solution across the mill lifecycle. The MH Series includes a range of SAG, ball, and rod mills in standardized sizes with a capacity of up to MW installed power, and is based on over 100 years of experience with grinding technologies.
Model Predictive Control for SAG Milling in Minerals Processing Steven J. McGarel, Rockwell Automation Introduction SAG and ball mills are generally accepted as the largest power consumers in a mining and mineral processing operation and can be 80% of total electrical energy consumed at a specific power consumption of around 20kWh/ton.
SAG mills with a rated power of up to 35 MW. As well as ever larger SAG mills, ball mills are also expanding in size. In the late 1990s the trend moved towards using GMDs to power these larger ball mills, as well as using the drive to vary the speed. GMDs quickly moved from 20'' ball mills, expanding to 24, 25 and then 26'' mills. In early ...

Oct 12, 2017· 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.
Two new SAG milling models are developed in this work, able to predict power or specific energy consumption, including the usual design variables such as mill size; balls charge level, solids concentration in the SAG mill feed and % of critical speed, but adding a .
