    comparison between roll & cone crushers: 1-roll crusher production smaller of fines than cone crushers and smaller reduction ratio. 2-rolls,because of their inability to yield high reduction ratio, have not been installed in recent years. 3-reduction ratio for rolls should not exceed similar to cone crushers. 4-rolls remain to be the best device for intermediate crushing.



    depending on the mill size the sag mills draws between 2 mw and 17 mw. the product from the sag mill is further reduced in size using pebble crushers and ball mills. hence, typical gold or copper ore requires between 2.0 and 7.5 kwh per ton of energy to reduce the particle size.
