brutning

Brutning is a term used in several Nordic languages, most commonly Swedish, to describe the mechanical size reduction of solid materials into smaller pieces. It covers processes such as crushing and grinding and is applied in industrial, agricultural, and construction contexts.

In mining and mineral processing, brutning is a stage of comminution that prepares ore for subsequent separation and refining. Materials may be reduced from large chunks to fragments or powders using crushers, mills, and other equipment. The term is often used to distinguish preliminary size reduction from finer milling stages.

In food production and agriculture, brutning can refer to milling or grinding of grains, seeds, coffee beans, and similar bulk materials to produce flour, meal, or powdered ingredients.

In construction and infrastructure, brutning may describe the production of crushed aggregates from rock or concrete for use in roadbeds and concrete mixes.

For English-language technical writing, the more common terms are crushing and grinding or the umbrella term comminution. In Nordic contexts, brutning is a traditional or regional term for these processes and appears in older literature and regional manuals.

Etymology: the word stems from Germanic roots related to breaking or breaking apart.
