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.

that net power rates will be the same in the pendulum and the crusher when the two distributions coincide (as they do in Figs. (4) thru (6). This permits us to determine the efficiency of power utilization in crushers and to predict the product size distribution which will arise from operating crushers at different power rates.

As with jaw crushers, these machines are compression crushers that use a stationary and moving piece of steel to break up the material. Cone crushers use a rotating head to crush the rock within a steel bowl. After initially being broken down in this manner, the material will travel through a narrow opening at the bottom of the bowl to achieve a finer grain size.
