Crushers have more efficient transfer of applied power to the breakage of rock than grinding mills. Typically a crushing flowsheet for a mineral processing plant will have from one-to-three stages of crushing. There are some cases where the process requires a fine dry product and a quaternary stage of crushing will also be included. Primary ...
