Comparison between Rod Mill and Ball Mill ore processing

Rod mill is a type of grinding mill whose grinding media is steel bar, while ball mill is steel ball 1 Rod mill are usually applied to grinding the wsn ore and rare metal in the reselection or magneticoredressing plant in order to avoid the damage caused byRod mills usually use steel rods with a diameter of 50mm100mm as grinding media, while ball mills use steel balls as grinding media The main difference between the two is the difference in grinding bodies The ball of ball mill is in point contact with each other, and the rod of rod mill is in line contact with each other, so their workingDifference between Rod mill and Ball mill Fodamon
