SAG Mill Control: It Shouldn’t be that Hard E & MJ

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

Optimization of a SAG Mill Energy System: Integrating Rock

Jul 01, 2019 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.

AUTOMATION ADVANCED CONTROL SOLUTIONS FOR MINING

present both in the ore feed system and within the mill itself. Additionally, BrainWave automatically adjusts its control settings to allow for different operation due to changes in ore hardness over time. With improved SAG mill control stability, the mill load can be optimized to increase crushing performance and production capacity.

Multi-component AG/SAG mill model ScienceDirect

Apr 01, 2013 1. Introduction. The Run-of-mine composition strongly affects autogenous mill operation. However, the effects of a varying ratio of hard and soft components in mill performance are not described by the current generation of AG/SAG models (Stange, 1996).For example, current JKSimMet models (Napier-Munn et al., 1996) assume a uniform feed, and describe it using a single set of average ore

Model predictive control of semiautogenous mills (sag

Oct 01, 2014 2.4. Multivariable predictive control. In the present work, a three-input-three-output scheme of control was performed. The total water feed to the mill (the feed water flow rate was added to the dilution water flow rate, so they could be specified separately, but for the SAG mill model, the total water content was the variable of interest), the fresh ore feed rate, and the mill rotation speed

Ore Hardness Testing -SAG Mill Tonnage Estimation Method

Jul 20, 2017 For design purposes, you need an estimation or prediction of your SAG Mill’s tonnage; well, there are 3 ways to generate good rock “ore” hardness testing data for SAG and ball mill circuit grindability from half drill core. We can abbreviate the discussion by saying there are three “religions” of grinding, and there are small-scale tests suitable for all three of the major religions

Mill Filling Prediction tool addresses productivity

Apr 02, 2020 SAG mills are a key asset for mineral processing operations as one of the critical stages of extracting mineral out of ore, and their continued stable operation is central to productivity. However, the performance of a SAG mill changes rapidly in response to conditions such as feed size and hardness as well as longer-term variability due to

The power draft of a SAG mill and its consequences are illustrated in Figure 2, wherein 5 days of operating data in a 32u14-ft SAG mill is plotted. The power draft of the mill is held between 6 and 7 MW, whereas tons per hour (tph) of ore feed to the mill shows wide variations between 1,000 and 1,600 tph.

Jig grinder Wikipedia

A jig grinder is a machine tool used for grinding complex shapes and holes where the highest degrees of accuracy and finish are required. The jig grinder is very similar to a jig borer, in that the table positioning and spindles are very accurate (far more so than a manual milling machine or lathe). It is almost exclusively used by tool and die makers in the creation of jigs or mating holes and pegs on dies. There are usually many peripheral elements to a larg
