Grinding media of ball mill and rod millAccording to the equipment name the rod grinder usually uses steel bars with a length of more than 500 mm as the grinding media while the ball mill uses steel balls with a diameter of less than 100 mm as the grinding media.
50-100mm steel rod is usually used as grinding medium in rod mill while steel ball is used as grinding medium in ball millThe steel balls are in point contact with each other and the steel rod of rod mill is in line contact with each other so their working features are obviously different.
