It is crucial to know when to replace crusher liners, as they must be replaced before they wear out to avoid damaging the crusher bowl, concave and mantle liner seating surfaces. In some cases, even with high-quality wear components, crusher liners may wear down to approximately 50% of their original weight. It is important to keep track of the liner wear to assess the extent of the crusher liner wear, as failure to do so may require stopping the crusher, which can reduce your profits.
Check for the following types:
● Mark the contact point between the small gear teeth on the adjustment cover drive ring and the drive ring teeth on the new crusher liners.
● Record the number of teeth used to compensate for the wear of the crusher liners.
● Before moving the bowl, record the total number of teeth moved by the drive ring and apply a horizontal liner mark on the side of the dust shell to serve as a baseline for determining the wear of the next set of liners.
● After installing a new set of liners, record the number of teeth moved by the drive ring and compare this number with the total number of teeth from the initial set of liners.
● When replace crusher liners and assessing liner wear, follow the instructions provided in the relevant crusher manual.
Typically, distorted wear profiles will lead to reduced capacity. Other symptoms of severely worn liners include high power consumption and ring bounce. Moreover, wear life can be shortened as wear sometimes concentrates in a small area rather than spreading evenly across the entire chamber. The chamber may need to be replaced before it is completely worn, leading to lower utilization and higher operational wear costs.
