Apr 20 2018 · the ball mills are often applied in mineral processing, they are e.g. an important part of the cement industry. key factor, which influences the milling process, is the granular flow of grinding media. the flow determines: energy consumption, time of milling and capacity; thus there is a need to describe the phenomenon. the discrete element method dem is a computational method, which
there are three types of grinding media that are commonly used in ball mills: An improved ontact model for ball mill simulation by th discrete element method.
In the case of ball mills, this is certainly not straightforward. let consider a simple example: the most common tumbling mill test used in the lab is the bond ball mill grindability test, used for nearly years to determine the bond work index, which is a number used to estimate how hard it will be to grind the material of interest.
three ball size classes are tracked for evidence of segregation at 75% and 60% of critical mill rotation speed. the ball distributions in the various segments at the end of mill revolutions suggest that varying axial liner profile configuration can affect ball segregation, particularly for the mill running at 75% of critical speed.
As the ball wear rate depends directly on the surface of the media charge, a small variation in power will lead to an important increase of wear rate. the risk of underloading or overloading the mill is an additional factor. direct measurement of the ball level in the mill, more accurate than power readings, as well as a control of it, is
