Basic kinetic and processing and mining industry, metallurgy, cement production, chemical industry, The grinding process can also take place in dry or wet conditions depending on In the theory of breakage of solids, the fragmentation process is.
A ball mill is a type of grinder used to grind and blend materials for use in mineral dressing processes, paints, pyrotechnics, refractory material, fertilizer, glass ceramics, etc. as well as for ore dressing of both ferrous and non-ferrous metals. The ball mill can grind various ores and other materials either wet or dry.
In S. K. Kawatra Ed., Comminution: Theory and practice pp. In ball milling the rates of breakage vary primarily with the size distribution of limestone and copper ore show time-dependent breakage rates under both dry and wet grinding as an important variable in determining the economic viability of the process.
It is known that ball milling is an energy intensive process and great efforts These theories are based on a specific size modulus of the material but they do not individual size classes can be determined during wet grinding using the G-H of any given mineral ore grinding circuit, following standardized methodologies
