Estimating optimal wear for cone crusher liners

 

What is an optimal wear percentage by weight for a set of cone liners?
 
— From Nilson O.

Answered by Steve Dolezal, Columbia Steel Product Engineering Manager:

“Depending on the machine design, we usually shoot for a minimum section thickness between the zinc surface and the crushing surface of 1.00 inch,” responds Steve Dolezal, who heads up our cone and jaw crusher design group.

“Sometimes however, the geometry of the chamber / machine just doesn’t allow for that. With that said, a good rule of thumb is 75 percent of the new set weight.”

Thanks for your question, Nilson!
