Though the effects of mixing soft and hard ores in a mill and their interactions are not widely investigated. To develop a general numerical model for AG/SAG mills, a dynamic model has been introduced, and its capability to simulate multi component ore breakage has been examined and compared with previous publications.

Three variable speed feeders draw ore from the base of the stockpile, with the choice of having hard, medium and soft ore from each of the feeders to make an appropriate blend for the SAG mill. Grinding Ore and quick lime added to the ore conveyor is fed to the SAG mill at a rate of 350 tph to 480 tph. The SAG mill (Morgardshammer, 8.0 m x 3.95 ...
Mineral processing typically involves the crushing and grinding of hard rock ore. Crushed ore is introduced to semi-autogenous grinding (SAG) mills, also known as primary mills, where grinding media is released like hammers to assist in the ore cracking / grinding …
The JKMRC has been studying and modelling industrial AG and SAG mills for over 40 years, but the ability to simulate the effects of blending hard and soft components on mill performance remains quite limited.In an effort to quantify these effects for modelling purposes, a series of laboratory, pilot scale and full scale tests, using multi-component feeds were conducted under the AMIRA P9O project.
This is achieved by using two stockpiles of limited capacity, to classify ore as hard or soft, depending on its expected grindability (Fig. 3). The SAG mill will draw from one of the two stockpiles at will to minimize the energy cost. If one of the stocks is emptied, the ore from the other stockpile is used.
