Hello everyone, I would like to know the last tendences in Css measurement instruments for giratory crushers. I know about Crusher Vision Automation System, C-Gap.

Leading is a technique for measuring the gap between mantle and concaves. The procedure is performed while the crusher is running empty. A lead plug is lowered on a lanyard to the choke point, then removed and measured to find out how much thickness remains after the crusher has compressed it. This measures the closed side setting. The open side setting is equal to this measurement plus the throw of the mantle. The minimum safe closed side setting depends on:

  • character of the material.
  • amount of fines in the feed.
  • liner/mantle shape
  • whether the crusher is operated as choke fed or regulated fed

Also see here, for cone crushers, a gap setting by ultrasonic measurement.

For gyratory crusher I have seen a  positioning system for the mainshaft installed on the hydraulic piston. Once you have the CSS or OSS adjusted, you may  keep and control the mainshaft position through the CLP.
