Jaw crushers are mainly used as primary crushers. Their main purpose is to reduce the material to a small enough size that it can be transported by conveyors to the next crushing stages. As the name suggest, jaw crushers reduce rock
Stages of Rock Crushing: Crushing Stations. It is common to use multiple crusher types within a project and set them up as stations in a circuit format to perform the necessary material reduction work. In many cases, primary, secondary, and tertiary, and quaternary stations are installed to reduce the rock to the desired size
Learn more below about a few different types of particle size reduction types. Crushing. Crushing is generally considered to reduce particles, like large rocks and stones, to gravel-sized material. This translates to roughly 0 to 5 mesh. Williams Crushers has a variety of machines that can perform crushing size reduction
This impact size reduction process was modeled by Kojovic (1996) and Djordjevic et al. (2003) using rotor dimensions and speed, and rock breakage characteristics measured in the laboratory. The model was also extended to the Barmac crushers ( Napier-Munn et al., 1996 ).

The feed is limited to 1 to 1.5 meters in size. Thus, based on reduction ratio, the rock size is reduced to 10 to 15 cm. Typical reduction ratios are: Primary crusher: 3:1 to 10:1; Secondary crusher: 6:1 to 8:1; Tertiary crusher: 10:1 Therefore, if a 3 mm crusher product is required, maximum feed size to the secondary crusher would be 240 mm.
