crusher. Tertiary crushing is usually performed using cone crushers or other types of impactor crushers. Oversize material from the top deck of the sizing screen is fed to the tertiary crusher. The tertiary crusher output, which is typically about 0.50 to 2.5 centimeters (3/16th to 1 inch), is returned to the sizing screen.
Secondary Crushers – Cone Crusher. The most common type of secondary crusher is the cone crusher.

They can be used in coal, salt, coke, glass, and trona operations, among others. Triple Roll Crushers combine a Single Roll Crusher with a Double Roll Crusher to form a crusher that is capable of achieving a 6:1 reduction ratio in the primary stage and a 4:1 reduction in the secondary stage while producing a cubicle product at high capacity.
capacity: long-shaft spider-suspended gyratory crusher, fixed-shaft gy- ratory crusher, and short-shaft gearless gyratory crusher. The gyratory crusher, whether used as a primary or secondary. is essentially a gravity-type machine. Material flows vertically from top to bottom. It receives a large coarse feed, usually run-of-mine,
Crushed stone, also called aggregate, refers to medium and coarse grain size material which is produced by man-made machinery and techniques rather than occurring naturally, such as in a riverbed or canyon. Crushed aggregate, often known as rock aggregate, is a crushed stone product that is mined. Larger stones are crushed in an …

A cone crusher in a secondary crushing application will typically work with a 3.5:1 to 5:1 reduction ratio. Tertiary cone crusher configurations typically work with a reduction ratio of 2.5:1 to 4:1. The reduction ratio is defined as the ratio of the feed size for which 80 per cent will pass (F80), divided by the product size for which 80 per ...
Primary crusher; Secondary crusher; Tertiary crusher; Primary crusher has the ability to receive the crushing material (a material that has to be crushed) directly from the source i.e., quarry that's why these types of crusher are fixed from where the material is taken.
