As with any material, rock particles only break when the applied tensile stress exceeds the tensile strength of the rock. However, in terms of comminution, the main interest is to derive reliable ways of assessing how a particular material breaks in a comminution device such as a crusher or a mill [].In general, the breakage of rock particles is dependent on two factors: …

Comminution. In addition to agglomeration, separation and mixing, comminution is one of the four basic operations in mechanical process engineering. Comminution usually means the splitting of a solid structure under the action of mechanical energy. Such comminution processes can be differentiated into real grinding or comminution ...

An essential element for sustainable use of renewable resources is an efficient comminution process for which the relation between energy input and size reduction is of great importance. Fine comminution of beech, oak, and spruce wood chips in cutting and hammer mills at different moisture content levels is investigated. The influence of the different process …

From blasting to downstream, processes are linked through the continuous reduction of the size of the rock. The effect of blasting is traditionally limited to fragmentation, although effects on crushing and grinding are also recognized and examined in the paper. Fragmentation prediction methods are reviewed to identify issues that need to be addressed in engineering models to improve the ...

A computational model for use with DEM (Discrete Element Method) is proposed for the five mechanisms applying to particle comminution in AG, SAG and coarse feed ball mills. Chipping and rounding are mechanisms that lead to preferential mass loss from corners and edges of particles and which produce shape change for the particles as well as size reduction.
