SAG Mill Control: It Shouldn’t be that Hard E & MJ
A control strategy recently implemented on a large variablespeed SAG mill at MMG’s Century Zinc operation in Australia is shown in the chart (found on pg. 32). In this case, mill speed is the primary manipulated variable used to control mill load. While there is no generic control strategy for SAG milling there is a considerable amount of reusable engineering. In contrast to an expert or
Difference Between Sag Mill vs Ball Mill mech4study
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. Interior of the drum uses the lifting plates. These plates

Operation Analysis of a SAG Mill under Different
As one of the machines widely used in mining, a semiautogenous grinding (SAG) mill can significantly improve the roughing efficiency of rock. But the SAG mill still faces the obstacles of significant energy consumption and empirical operation parameters. In order to obtain the optimal operation parameters of a SAG mill, in this paper, the discrete element method (DEM) is used to simulate the
Optimise SAG mill capacity and avoid FLSmidth
With variances in mill ore feed rate, mill speed and slurry density, critical impacts can occur in your SAG mill. The speed at which these variances are adjusted for is thus crucial for minimizing damage and optimizing liner life. Every second counts, and adjusting these parameters within seconds can have a significant effect on the wear of your SAG mill, which will effect on your bottom line.

01/01/2016· Mill Power, Load and Mill Operation. The operation of AG and SAG mills may be guided by the relation between maximum mill load and mill power as given in Equation and modified later by Morrell (Equation ). The following general remarks are of interest: 1. While starting a mill, a low power draw suggests the feed rate has to be increased. 2. A high power draw indicates a high mill loading. 3
