Comminution is defined as the action of reducing a material, especially a mineral ore, to minute particles or fragments . In the minerals industry, breakage is achieved through blasting, crushing and milling, while in the pharmaceutical and chemical industries size reduction is usually through milling.

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). ...

Comminution is the process/action of reducing solid materials from their standard particle size to smaller average particle size. Here's what you need to know: The Methods of Comminution When it comes to comminution, there are many means to an end. Some of the most common processes are cutting, grinding, crushing, pureeing, delumping ...

Comminution can be defined as the process of reducing solid material such as rock into fragments by crushing, grinding or drilling. To predict a rocks comminution behavior test methods are used, the results of which can be used to plan downhole tool assemblies. Determining the strength of rock is also essential for engineers to design tunnels ...

Comminuted fractures are a type of broken bone. The term comminuted fracture refers to a bone that is broken in at least two places. Comminuted fractures are caused by severe traumas like car accidents. You will need surgery to repair your bone, and recovery can take a year or longer. What is a comminuted fracture?

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 ...

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 ...

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'.
