Comminution - Wikipedia
Comminution is the reduction of solid materials from one average particle size to a smaller average particle size, by crushing, grinding, cutting, vibrating, or other processes. In geology, it occurs naturally during faulting in the upper part of the Earths crust. In industry, it is an important unit operation in mineral processing, ceramics, electronics, and other fields, accomplished with many types of mill. In dentistry, it is the result of mastication of food. In general medicine, it is one of the most traumatic forms of stone fracture.

COMMINUTION: Liberation, Crushing, Grinding
• Comminution, is the process whereby the particle size of the ore is progressively reduced until the clean particles of the mineral of interest is “Liberated” from the matrix of gangue ...
Comminution - an overview | ScienceDirect Topics
Comminution is only one step in the chain of processes required to produce ceramic materials and it cannot be optimized independently; the entire process has to be optimized. The critical intermediate stages in the process must be capable of being described in terms of their intermediate aims and, thereby, be rendered capable of being checked.
Comminution - an overview | ScienceDirect Topics
Process simulation is now used extensively in both the design of new comminution plants as well as in the optimization of existing operations (Evans et al., 2013; Hart et al., 2012). When optimizing or designing a comminution circuit, the process engineer will use a software package that can predict changes to ore breakage as the circuit flows and/or equipment configurations are changed.

Comminution - liming
Comminution is the most energy intensive process stage in the mining industry. It uses at least 3% of the global electricity and, according to the Coalition for Energy Efficient Comminution, accounts on average for more than 50% of a mine’s energy consumption and 10% of the total production costs.
Comminution | Centre for Minerals Research
Comminution is a process of reducing the size of ore particles to liberate the minerals in preparation for extraction in downstream processes, and classification is installed to ensure that liberated minerals enter the recovery section of the process plant and those not ready are recycled.

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’.
Comminution Testing Equipment in Mineral …
The First Principle of Comminution It sometimes happens that the obvious is long disregarded, and this applies to the first principle of comminution. Over the years many careful laboratory investigations of comminution phenomena have been made and published. These included accurate measurements of energy input and product size particle distributions, but the results differed among themselves ...

comminution: [ kom″ĭ-nu´shun ] the act of breaking, or condition of being broken, into small fragments.
comminution process of ores - debruijnwijnimport.nl
Comminution is the process where ore particles are liberated from gangue material through progressive size reduction in the form of crushing, grinding, cutting or vibrating. The costs associated with power supply, grinding media, and liners used in comminution circuits almost always represent the single largest cost in gold extraction processes (Mosher, 2005).

Comminution and grinding - Meats and Sausages
Comminution and Grinding. The purpose of the comminution process is to cut meat down to the required particle size. The typical machines are: Dicer; Grinder; Dicer. Dicer cuts into uniform size cubes that may be used in many dishes or specialized sausages. For example Polish Krakowska sausage is done with visible chunks of meat.
Comminution (Crushing, Milling, Grinding)
Comminution (Crushing, Milling, Grinding) Comminution is the act of breaking solid particles apart into smaller pieces. Several Mimic objects perform comminution, and they all use the same mechanism. Crusher; Mill; Breakage Matrix. The core component of the comminution process is …
Comminution : ALS
ALS comminution process development testwork, at both laboratory and continuous pilot plant scales, minimises the technical risks associated with the development of comminution circuits. Crushing and grinding of ores is a significant capital and operating cost in many mineral processing plants, and up to fifty percent of the operating costs can be attributed to crushing and milling alone.
