Theory of Comminution

Theory of Comminution. H. J. Kamack (E. I. du Pont de Nemours & Co., Inc., Wilmington, Del.)—Rittinger's law usually is stated to the following effect: "The work (or energy) consumed in particle size reduction is proportional to the new surface area produced." The law has been stated substantially in this way by Taggart, Berry, Dalla ...

Pretreatments

However, in practice, comminution does have drawbacks, especially the danger that comminuted fibres will combine with grease (blocking pumps and pipes) and the need for relatively frequent maintenance work on fairly delicate equipment. On these grounds, comminution is now only rarely advocated. On the other hand, it sometimes replaces fine ...

About

Comminution is the action of reducing a material, especially a mineral ore, to minute particles. It is an essential process for much of the mining industry where it is used to fracture rock ores into fine particles in order to liberate and then recover the valuable minerals (e.g. copper, gold, platinum, zinc, magnetite). ...

Mineral Comminution and Separation Systems

4. Comminution System To achieve the goal of recovering these concentr ates, the raw ore must be reduced to fine size prior to separation. This process is called 'comminution' or 'size reduction'. Generally there are two major objectives for comminution in mineral beneficiation: The first objective of comminution is 'liberation'.
