PDF Identifying the apparent and true grinding limit University of Cincinnati

The observed plateau in particle size is defined as the apparent grinding limit which is mainly influenced by the stability of the suspension. As can be seen in Fig. 2 the development of the primary particle size also reaches a constant value which is defined as true or real grinding limit. This true grinding limit is the minimal achievable ...

In other words, HPGR is a more selective size reduction process that can better protect graphite flakes with a coarser particle size. The ball mill resulted in more transgranular breakage of particles, which led to a poor liberation degree of graphite at a given particle size and therefore required finer grinding to produce the same flotation ...

How the Nano Milling Process Works | Blog Hockmeyer

How the Nano Milling Process Works | Blog Hockmeyer

Nano mills are most efficient when the incoming particle size is smaller than the exit screen and no larger than the media. This means that the target particle distribution for premilling should be between 25 um and 100 um, a distribution that can often be achieved with a very short premill cycle in a highenergy mill.
