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.
We have influenced a selection of many of the major HPGR and mill installations. Our team is experienced in installing crushers and HPGR's into existing SAG Mill/ball mill circuits both to balance the power split between the SAG Mill and ball mill and to increase the overall circuit tonnage and performance.

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 ...

As with most models, the power split between the SAG and ball mills is evaluated and the transfer size (T 80) necessary to balance the power draw between the two stages is estimated. If that transfer size is within the specified limits, then the calculation proceeds to calculate the E SAG and E ball .
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.
A SAG mill with a 44' (13.4m) diameter and a power of 35 MW (47,000 HP) has been designed. 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.

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.
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.

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 .
Traditionally, many engineers have approached SAG circuit design as a division of the total power between the SAG circuit and ball-mill 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 ball-mill circuits.
