Role of feed moisture in high-pressure roll mill comminution
The high-pressure roll mill, HPRM, is an example of continuous grinding under the confined particle–bed mode (Kellerwessel, 1990, Fuerstenau and Kapur, 1995). However, a completely confined particle–bed mode of grinding is difficult to attain in the HPRM because of the well-known end effects that invariably result in some leakage of …
Mill and higher pleasures – Ask a Philosopher
Indeed, in Utilitarianism (Ch.2) Mill refers to critics who say it is a "doctrine worthy only of swine". To avoid these consequences, Mill said there were higher and lower pleasures. Importantly, a small amount of a higher one was worth more than any amount of a lower one, thereby avoiding the eternal oyster and myriad contented pigs problems.
An industrial comparative study of cement clinker
In high-pressure mills the input energy is directly transferred to a confined bed of particles under compression where comminution occurs primarily by very large inter-particle stresses generated locally within the compressed bed. HPRM's are generally placed upstream of conventional ball mill systems as pre-grinding units to produce a fraction ...
