Measuring the Crusher OSS CSS Closed Side Setting

2016-2-18  The measurements given in the table should be deducted from the open-side setting (OSS) for calculation of the closed-side setting (CSS) according to the size of the crusher to be adjusted. Example: If the measurement of the OSS in the C160 model is 191mm (7 1/2”), then the CSS will be: 191 - 41 = 150 mm (7 1/2” – 1 5/8” = 5 7/8”).

Exact crusher gap adjustment in rotary crushers

Rotary crushers for quarries or ore mines can grind up to 3500 t of material to the desired grain size in one hour. For this purpose an eccentric bearing bush generates a rotary-oscillating movement of the crusher axle, thereby constantly changing the gap between the crusher jaws and the crushing cone.
