A coupled CFD–DEM model for tumbling mill dynamics—Effect of lifter

In comminution circuits, grinding is the most energy-intensive process. Although significant work was focused on the charge particle dynamics via only DEM in the past, but lifter effects and slurry viscosity have often been overlooked. This work aims to develop a coupled CFD–DEM model to precisely predict mill dynamics involving slurry, …

SAG mill pulp-lifter design, discharge and backflow

In particular, the material transport issue is the focus since the efficiency of mill discharge via grate, pulp lifter channels, and discharge trunnion determines the mill throughput. The ...

Performance characterisation of AG/SAG mill pulp lifters …

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.

A coupled CFD–DEM model for tumbling mill dynamics—Effect of lifter

As the mill speed and lifter face angle increased, there was a gradual upward shift in the COC location. In contrast, a notable downward shift of approximately 20%–25% in the COC location was observed in slurries containing 15 and 40 wt% solids compared to pure water (0 wt% solids), primarily due to increased viscosity. ...

The Selection and Design of Mill Liners

Uni-Direction Profiled Liners – The lifter has different leading and trailing profiles, Figure 4. The profile can be better customised to suit mill speed and filling and therefore optimise performance, and it allows more material in the lifter for a given base width, but the mill must only run in one direction. 7.

Impact Load Behavior between Different Charge and Lifter …

For ball mills, it is dependent on the rotation of the mill shell for lifting the grinding media to impact the particle, and the mill shell, grinding media, particle and lifter are contents of the grinding environment [5,6].The grinding efficiency is affected by operating variables, such as the charge, lifter and controlling parameter.

SAG Mill Grinding Circuit Design

AG and SAG mills are now the primary unit operation for the majority of large grinding circuits, and form the basis for a variety of circuit configurations. ... liner design and configuration can have a substantial effect on mill performance. In general terms, lifter spacing and angle, grate open area and aperture size, and pulp lifter design ...
