Jaw Crusher Liner Wear Instruction
Liner wear in the jaw crushers causes great costs in the aggregates and mining industry. Change of the geometry of the crusher liners is a major reason for these costs. The ability to predict the geometry of a worn crusher will help designing the crusher liners for enhanced performance.
With a small jaw crusher, the wear of the crusher liners for the various settings of the crusher has been investigated. The experiments were performed with highly abrasive quartzite are known for, done. Crushing forces were measured, and the movement of the crusher was pursued together with the wear on the crusher liners.
The test results show that the wear mechanisms are different for the fixed and moveable liner. If there is no relative displacement distance between rock and liner, this does not apply to stone crushing plant applications where wear observed, although there is no macroscopic sliding between the rock material and the liner is true. For this reason, SBM jaw crusher has been held to account for wear by the sliding of the local particle-induced ground changed. The predicted worn geometry is similar to the real crusher.
Cone Crusher Wear liner
A cone crusher is a machine commonly used in mining and aggregates. In a cone, the geometry of the crushing chamber is crucial for performance. The aim of this work, where the wear was studied in a jaw crusher, is to implement a model to predict the geometry of a worn cone crusher.
In previous studies, a model for cone crushers for laboratory scale crusher with rolls 200 mm in diameter was detected. The present study examines the applicability of the model for large-scale crusher with rolls of 0.76 m in diameter. The study results show that the model is valid for large-scale crusher over a wide range of operating conditions including variations in feed size, crusher roll speeds, gap settings and the roll surface configurations. Could be an important finding was that the model parameters from laboratory-scale testing determined crusher used for large-scale crushers, which indicates that the model parameters do not depend on breaker size or operating conditions.
