Modelling Sag Milling Power And Specific Energy

Modelling Sag Milling Power And Specific Energy

Distribution affects the SAG mill load and the load affects directly the mill power and the efficiency of the mill operation (Van Nierop and Moys, 2001). If a SAG mill has been designed with a conventional power or specific energy model which do not con-sider the projected feed size distribution it is likely that this mill.

The Evolution Of Grinding Mill Power Models Springerlink

Mill power models have been used in a variety of ways in industrial practice since power directly equates to throughput and fineness of ground product. We first start with Hogg-Fuerstenau Power Model and show how this model successfully predicted the power draw of many grinding mills in several mining operations. Then, we show how this model was on the verge of being able to predict the.

How Do I Track The Mill Liner State Intellisense Io

The Grinding Application's Liner Wear Model tracks the state of the liners and lifters in the SAG or Ball Mill, by modelling the decrease in lifter height and angle across different liner sections in real-time. The model uses historical information data about liner wear to relate the wear rate with mill throughput and operating regimes.

Ag & Sag Mill For Mineral Processing Wet & Aerofall Sag

What is a SAG mill The structure of the SAG mill (semi-automatic grinding mill) and the AG mill (autogenous grinding mill)are exactly the same, except that a certain proportion of auxiliary grinding media such as steel balls or steel rods are added as needed. During the process of the AG mill operation, some ores with diameters greater than 20mm but less than 80mm are not easily ground.

The main problem with these harder ore types is that they hold up in the SAG mills, restricting throughput. The SAG mill feed is controlled by the mill weight, measured by 4 load cells on the mill bearing system. Therefore if the ore does not grind quickly enough in the SAG mills, the mill weight increases and the control system reduces feed to.
