Frequently Asked Questions

The appropriately sized hollow bulb is loaded in between the fixed and moving plates/mantles of the cleared crusher. When the gap closes the bulb is squeezed and air pressure increases proportional to the CSS. This pressure correlates to a gap size for the chosen bulb size with this value being presented on the handheld unit readout. The C-Gap can be calibrated easily with a lead weight etc. It is recommended that the C-Gap is calibrated every month on each crusher to ensure continued accuracy.

Yes- apart from HPGRs and roll crushers. For fast-spinning cone crushers such as the Metso HP at small CSSs (< 40mm), the CSS can only be measured upon shutting the crusher down for daily/shift checks OR when the crushers can be braked. Otherwise, the C-Gap is compatible with all other cone crushers (Sandviks, Jacques etc), Gyratory and Jaw Crushers.

With the bulbs being constructed of high wear-resistant rubber, previous operations have reported these bulbs need to be replaced annually. Please follow the instruction and please ensure the chamber is free of rocks before measuring the CSS
