The reduction of a rock to progressively smaller particles by natural methods (weathering, erosion, or tectonic movements) or manufacturing processes (breaking, crushing, or grinding by mechanical means). Syn: pulverization; trituration.
The breaking, crushing, or grinding of coal, ore, or rock.
particle size reduction by breaking, crushing or grinding of ore to reduce ore to the size required for mechanical or chemical separation.
Breaking into a number of small fragments
breaking up of ore to make gold available for treatment
Mechanical shredding or pulverizing of waste. Used in both solid waste management and wastewater treatment.
The process of breaking down metal into individual particles through grinding and flaking operations, among other procedures.
Comminution is the crushing and grinding of ore to make gold available for treatment. (See also " Milling").
Mechanical shredding or pulverizing of waste; used in solid and water waste treatment.
The reduction of stone to small particles through any natural action such as frost action (crevices formed through alternate freezing and thawing); biochemical action of plants, trees, and organisms growing in rocks; wind corrosion (a natural phenomenon akin to sand blasting); ocean wave action; glacial scouring; and tectonic action (the shearing and jointing of rocks caused by stresses in the earth's crust).
Comminution is one of the four main groups of mechanical processing and describes the movement of the particle size distribution (grains, drops, bubbles) into a range of finer particle sizes (The other groups are agglomeration, separation and mixing).
