Indirect Particle Size Distribution Control in Cone ...

As a result, the most common control objective is regulating the crusher power or the closed side setting, not actual size reduction or the product size. Cone crushers are typically operated at constant operating parameters (setting mode) or by control modes that regulate crusher load (load mode), that is, crusher power draw or piston pressure.

The closed side setting, c s s, is defined as the smallest distance between the mantle and the concave, and the open side setting, o s s, is defined as the greatest distance at the same height . Due to the eccentric motion, if at a given vertical position this distance is the c s s, the o s s will be in the diametrically opposite position.

Cone crusher basics in 4 minutes — SRP

The widest distance is known as the open side setting (OSS) and the narrowest, the closed side setting (CSS). These settings are important. The OSS is the largest distance between the concave and the mantle at the bottom of the crusher, so it determines the largest particle size of the outgoing product.

Measuring the Crusher OSS CSS Closed Side Setting

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.
