Getting more use from a liner set involves understanding how the chamber changes as the liners wear. Remaining wear material is one consideration; how the chamber accepts and processes feed also matters.
For Miles Sand & Gravel, CWP compared new and worn cone crusher liner profiles to evaluate those changes. The team used a new liner set as a reference alongside the worn components returned for analysis.
The study illustrated a 3-inch feed-size reference at a 5/8-inch closed-side setting. With the new profiles, that reference sat within the chamber’s nip point. With the worn profiles at the same setting, it sat above that point, illustrating a change in chamber geometry that could affect material acceptance and throughput.
A preliminary engineering review indicated that the existing profile appeared appropriate. The findings helped focus the discussion on how wear changes the chamber and how continued liner use should be evaluated alongside production requirements.
The study provided a clearer basis for reviewing liner condition, discussing changeout timing and identifying further application questions.
