Grinding in ball mills is an important technological process applied to reduce the size of particles which may have different nature and a wide diversity of physical, mechanical and chemical characteristics. typical examples are the various ores, minerals, limestone, etc. the applications of ball mills are ubiquitous in mineral
In this study, the effect of circulating load cl and test sieve size p,, which are inaccuracies of bond grindability, on the bond ball mill grindability g hg and work index w, are investigated based on four samples of natural amorphous silica.
The grinding process in ball mills and vertical roller mills differ fundamentally. in a ball mill the comminution takes place by impact and attrition. the comminution in the vertical roller mill takes place by exposing a bed of material to a pressure sufficiently high to cause fracture of the individual particles in the bed, although the ...
