US5580003A - Method for controlling a gyratory crusher ...
A gyratory crusher has two crushing shells (4, 5) defining between them a crushing gap (6). In operation, the crushing gap is adjusted as a function of the determined crushing-shell wear calculated on the basis of reference data on the established rate of wear of the crushing shells (4, 5) in previous crushing operations involving the same or a similar raw material.

Measuring the Crusher OSS CSS Closed Side Setting
After measuring the crusher’s OSS, the CSS should be calculated to define what the opening of the crusher is to be and enable adjustment to the desired setting. The way we measure the opening varies according to the profile of the jaw: top-top, top-bottom or bottom-top. The tables for the cavity should be checked to figure out which way

principles of operation in gyratory crushers
1/1/2016 Gyratory crushers can accept 8–10% moisture in operation, but the fine content should be preferably less than 10%. The crushing action in gyratory crushers is regarded as rings or 'helics' (spirals) of feed down through the crusher of which a single section may be regarded as similar to the jaw crusher.

What is the eccentric throw? — SRP - SRP — Home
The eccentric throw is one of the most important parameters in defining the job that your cone crusher does. The mantle in a cone crusher spins in conical pendulum motion. That means it doesnrsquo;t stay in the center of the chamber ndash; it sweeps around moving closer and further away from the concave. This is what creates the crushing action. At a given point on the concave, material is ...
