Siktsteg

Siktsteg is a term used in Swedish industry, particularly in mining, quarrying, and material processing, to refer to a screening step in which material is sorted by size using screens. The word combines sikt meaning sieve and steg meaning step or stage. In a typical processing circuit, a siktsteg designates the stage where material is passed over one or more screen decks to separate it into size fractions, often coarse, medium, and fine streams. The choice of screen openings (siktöppningar) determines the cut size for that step, and the resulting fractions may be directed to subsequent processing steps or to final product streams.

In practice, siktsteg can refer to both the physical equipment (such as vibrating screens or static grizzly decks) used to perform the screening, and to the procedural step within a plant's overall throughput. It is common in aggregate production, ore beneficiation, recycling, and waste management operations, where staged screening improves efficiency and product quality. The term is typically used in Swedish-language manuals and plant layouts, though the concept is equivalent to the English term screening step or size separation step.

Note: The term reflects a general concept of size-based separation in industrial processing and is most commonly encountered in Swedish-language contexts.
