As the feed is crushed, it falls and exits the crusher through the space at the bottom. The eccentric gyration of the mantle means that at any moment this space is narrowest at one point, and widest at the opposite point. The widest distance is known as the open side setting (OSS) and the narrowest, the closed side setting (CSS).
As gravity pulls the rock down from the top of the crushing chamber (feed) to the discharge (close-side-setting), all rocks undergo multiple impacts causing them to get crushed. ...

A high-speed, gyratory, cone crusher or fine-reduction crusher in the same plant just as consistently produces material 70% of which passes a square opening test sieve, equivalent to its close-side setting. In both cases all material is reduced to a one-way dimension not exceeding these respective open and close-side settings.
closed side setting position. The maximum feed size in GP cone is the same as closed side feed opening. Maximum feed sizes are also stated in chamber configuration tables later in the guide. Closed side setting (CSS) The closed side setting defines the reduction ratio in GP cone crusher and has significant bearing on product gradation, capacity
Crusher-Setting, Product-Size. Gyratory and jaw crushers are always rated at certain open-side or close-side discharge settings. In order that we may select the particular curve, of a group of curves, which will most nearly represent the product of a crusher having any given discharge setting, it is important to know approximately what ...
It is also used to determine the required open-side settings (jaw crushers and gyratory crushers) or closed-side settings (cone crushers) for a given product size. P80 = 25400 x Oss x (0.04Wi + 0.40) P80 = 25400 x Css x 7Ecc x (0.02Wi + 0.70) / (7Ecc – 2Css) Where Oss = Open-side setting in inches
The actual minimum safe closed side setting of a crusher will vary somewhat, for any given crushing machine, depending upon the character of the material, the amount of fines in the feed, and whether the crusher is being operated under choke-feed or regulated feed …

crusher Whenever a jaw crusher is off and at rest (stopped), it will remain in the open position at its open-side setting (OSS). However, the adjustment of your crusher is performed at its closed-side setting (CSS). OSS is measured while the crusher is stopped. CSS is calculated by deducting a certain amount (the average stroke) from the OSS.
Developed by Mintap, based in Perth, Western Australia, the Closed Side Setting (CSS) measurement device – the C-Gap – is now available through South African-based Control Systems Rustenburg. C-Gap offers accuracy, safety and reliability to the quarrying and mining industries for the measurement of the CSS in gyratory, jaw and cone crushers.
