Crushers and Their Types – IspatGuru
Fig 1 Methods for size reduction of materials The reduction of size of the material when it pass through a crusher is expressed as reduction ratio. The reduction ratio is the ratio of the crusher feed size to product size. The sizes are usually defined as the 80 % passing size of the cumulative size distribution. Types of crushers

The cone-type gyratory, of which the “Symons’ is perhaps best known, is pre-eminent as a secondary crusher and is capable of effecting a size reduction ratio of the order of 6-8:1. This type of machine is best employed in close-circuit with a screen but is unsuitable for minerals of an argillaceous character. Protection against the inclusion of steel in the feed is imperative and all units

TECHNICAL NOTES 5 CRUSHERS
Jaw crushers are operated to produce a size reduction ratio between 4:1 and 9:1. Gyratory crushers can produce size reduction ratios over a somewhat larger range of 3:1 to 10:1. The primary operating variable available on a crusher is the set and on jaw and gyratory the open-side set (OSS) is specified. This reflects the fact that

Jaw Crusher
The first stage of size reduction of hard and large lumps of run-of-mine (ROM) ore is to crush and reduce their size. Softer ores, such as placer deposits of tin, gold, mineral sands, etc., do not require such a treatment. Large-scale crushing operations are generally performed by mechanically operated equipment such as jaw crushers, gyratory crusher and roll crushers.
