A jaw crusher usually wears more manganese steel per crushed tonne than a gyratory crusher. Feeding fines into the crusher may increase peak stress loads because of packing ? ie material being compacted as far as it compacts. This is enhanced by moisture, which again is highest in the fines and quite common in underground mines.
