These crushers operate on a wet slurry-type feed to improve crushing performance and possibly reduce metal wear. The improved water-flush crusher is an example of an incremental improvement of an existing process. Energy efficiency in size reduction by grinding is typically less than 20 percent, indicating an enormous potential for improvement.
