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 Earth's 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 bone fracture.

Most of the energy in mineral processing (power and steel) is used in crushing and grinding rock. This process is simple at a high level, and able to be modelled based on simple physics. However, understanding and optimising comminution processes have presented researchers and practitioners with significant challenges. Most of the improvements in the last 60 years have been in . Machine scale
Steel consumption is determined using abrasion index from the abrasion test and procedure given in “Minerals Processing Plant Design”, also by comparative studies with existing plants. Using testwork results with preliminary economic and geographic data, most of the basic circuits can be eliminated and the final detailed study can be made on one or two circuits, possibly three at the most.

first objective of comminution is ‘liberation’. Liberation is the process to unlock composite minerals in the raw ore into more independent particles, and without it we cannot collect the wanted components only. The second objective of comminution in mineral processing is to adjust the size of mineral particles to adapt to the optimum size

Mineral processing can involve four general types of unit operation: comminution particle size reduction; sizing separation of particle sizes by screening or classification; concentration by taking advantage of physical and surface chemical properties; and dewatering solid/liquid separation. In all of these processes, the most important considerations are the economics of the processes and this is dictated
Mineral particles smaller than 50 micrometres can be classified by different optical measurement methods, which employ light or laser beams of various frequencies. Comminution. In order to separate the valuable components of an ore from the waste rock, the minerals must be liberated from their interlocked state physically by comminution. As a rule, comminution begins by crushing the ore to
eral processing as follows: “Mineral processing is the first step in the solid mineral extractive process. The goal is to produce granular mate-rial which meets a specific set of requirements in terms of material composition and physical characteristics (espe-cially granulation). The minerals are then used either as
In order to separate the minerals from gangue (the waste minerals), it is necessary to crush and grind the rock to unlock, or liberate, valuable minerals so that they are partially or fully exposed. This process of size reduction is called comminution. The crushing and grinding process will produce a range of particles with varying degrees of liberation (Figure 2). Any particles that exceed a target size required
