Crusher Screen
The Crusher screen displays important operating conditions to ensure the crusher is within tolerances.
Operating Conditions:
• Lube Flow
• Lube Oil Temperature
• Bowl Clamp Pressure
• TIR Pressure
• Hydraulic System Pressure
• Hydraulic Oil Temperature
• Closed Side Setting (CSS)
You will also perform crusher related functions from this page, including clearing the crusher, raising/lowering
the bowl, and resetting the CSS.
Closed Side Setting (CSS)
The CSS is the smallest distance between the bowl liner and the cone mantle and is adjusted by rotating the
bowl up/down to achieve a particular minimum product size.
NOTE: The minimum closed side setting for any chamber configuration or crushing condition is that setting
that can be maintained without bowl float.
The actual closed side setting that is chosen is necessarily site-specific and depends on a variety of factors.
If a particular closed side setting results in bowl float, then the closed side setting must be increased until the
bowl float stops. If this results in an undesired product specification, then changes to the chamber, the crusher
speed, and/or the input feed material must be made, as required.
