There are lots of different kinds of crushers from jaw crushers to impactors and cone crushers. Crushing is an versatile process and the kind of crusher you need depends on the 'stage' of crushing. The three main stages of crushing are primary, secondary, and tertiary - all of which have their own unique benefits.
Details
The method depends on the cone crusher model. A smaller CSS will give you a finer output. However, a bigger CSS will produce a coarser product. Compared to jaw crushers, cone crushers have a higher reduction ratio, usually between 6:1 and 8:1 in a single pass. They also make a more cubic and evenly-shaped product because of the …

A short-head cone crusher has a short crushing chamber and it is designed for the production of finer output sizes, generally between 6 mm and 25 mm. A fine cone crusher, also known as a tertiary cone crusher, is used for the production of They are manufactured to produce very fine output sizes, mostly below 6 mm.
Details
In summary, a cone crusher operates by rotating the mantle and the concave at high speeds, which compresses and breaks down rocks into smaller pieces. The gap between the mantle and the concave is used to determine the size of the output material, and the adjusting mechanism is used to control the gap and adjust the size of …
