Siktning

Siktning is a Swedish term with several related meanings, depending on the context. In everyday use it most often refers to sighting or aiming, particularly in firearms, archery, and optics. Siktning in this sense involves aligning the weapon’s sights with a target and adjusting for distance, wind, and ammunition to achieve a known point of impact. The process typically starts with selecting a zero distance (often 100 meters for rifles), choosing appropriate optics or sights, and establishing a stable aiming position. After firing a test group, the actual impact points are compared to the aim points, and elevations and windage are adjusted accordingly. The resulting settings, or the “zero,” are documented for repeated accuracy. Subtypes include iron-sight alignment, optical scope zeroing, and rapid aiming with red-dot or holographic sights.

In industrial and technical contexts, siktning refers to screening or sieving, the separation of material by particle size. This involves passing a feed stream through screens or sieves with openings of specific dimensions, often on single or multiple decks. Throughput, screen openings, and material characteristics determine the efficiency and cut size—the point at which material is classified as fines or oversize. Siktning is a central process in mining, quarrying, aggregate production, recycling, and agriculture, where consistent size separation is required for downstream processing or product quality.

Overall, siktning denotes the act of aiming or directing attention toward a target, as well as the technical process of separating material by size, depending on the field.
