Performance characterisation of AG/SAG mill pulp lifters

2014-8-1  The pulp lifter is an integral component of autogenous (AG) and semi-autogenous (SAG) grinding mills as it controls the throughput, performance and efficiency of mills. The slurry transport from the AG/SAG mill through grate holes into the discharge trunnion is the main function of the pulp lifter. This process develops complex flow behaviour

Slurry flow in mills with TCPL — An efficient pulp lifter

2006-6-1  Pulp lifters, also known as pan lifters, are an important component of grate discharge mills (GDM). The GDM include autogenous (ag), semiautogenous (sag) and grate discharge ball mills. The purpose of the pulp lifters is simply to transport the slurry passing through the grate holes into the discharge trunnion.

SAG Mill Liner Design Mineral Processing & Metallurgy

2016-6-6  As mill sizes increases, the required volumetric capacity of the pulp lifters grows proportionally to mill volume. Since AG/SAG mill volume is roughly proportional to the mill radius cubed (at typical mill lengths) while the available cross-sectional area grows only as the radius squared, pulp lifters

Determination of lifter design, speed and filling effects

2004-11-1  The number of very low energy impacts (0.1 J) for a mill with only two lifters is the highest, as shown in Fig. 10. However, starting from relatively modest impact energy (2 J), the number of impacts per second for the two lifters case drops at a much higher rate than for the mills with 14 and 22 lifters.

2016-6-6  in variable speed mills, this may be achieved by reducing mill speed; and in both cases this may be achieved by design by increasing the lifter face angle. Traditionally, the number of shell lifters used in a SAG mill is equal to twice the number of the feet in the mill shell diameter (e.g., a 34-ft-diameter mill shell would have 68 shell lifters).

What’s the difference of Ball mill, SAG mill, AG mill?

2018-1-11  Attrition mill is a type of grinding mill by kinds of media to crush lump to powder-like substances. The impact can be rock on rock such as in an Autogenous Grinding (AG) mill, rock and a small ball charge (~10%), used in Semi Autogenous Grinding (SAG) mills, balls of various sizes in Ball Mills and less commonly these days, steel rods in Rod Mills.

Investigation of Effect of Number of Lifters on

The number of lifters of mill shell liners, mill rotation speed, and filling percentage of grinding media are three of the most important parameters influencing the charge behavior and the trajectory of ball motion inside the SAG mills, and consequently, their performance. In this paper, the milling operation of pilot-scale SAG mills using the discrete element method (DEM) is investigated.
