AN OVERVIEW OF THE DESIGN CONSTRUCTION

The final selection of the SAG mill volume operating ball charge level and installed power was made with a view to ensuring that there was ample room for expansion in the future without the need for a second SAG mill The volumes of the mills were made deliberately generous to ensure that full installed power could be achieved It can be seen

SAG Mill Control: It Shouldn't be that Hard

SAG mill control fundamentally means managing the load in the mill by adjusting the feed rate of ore to the mill and/or manipulating the rotational speed of the mill The best way to measure load is to mount the mill on load cells The load cells are calibrated to measure the total weight of water grinding media (balls) and ore in the mill but not the weight of the mill itself While many

MEI Blog: Where are SAG mills going?

In our recent conversation Prof Alban Lynch was very sceptical about where semi-autogenous grinding (SAG) mills have gone and thinks they have taken us along the wrong track He feels that they may be attractive in terms of high productivity but says that their energy efficiency is poor and I feel that these immense machines are going to turn into very large ball mills
