At the end of this lesson students should be able to: Explain the grinding process. Distinguish between crushing and grinding. Compare and contrast different type of equipment and their components used for grinding. Identify key variables for process control. Design features of grinding equipment (SAG, BALL and ROD MILLS)
Figure 2: Rod Mill Ball Mills Description Ball mills are similar in concept to the rod mill but are charged with steel balls in place of the rods. The mill consists of a cylindrical drum, sometimes tapered at one end, and usually has a charge of steel balls (up to 40% by volume) ranging in size up to 125mm for larger mills.(PDF) Comminution in mineral processing ResearchGate,ball mill, rods, tube mill etc. Mainly, the active fo rce behind crushing is compression or impact and the common operation for grinding is attrition[14] (Figure 4.1).

Both types of mills have their advantages and disadvantages, and the choice between the two depends on several factors. Ball Mills: Ball mills are cylindrical devices used to grind materials such as chemicals, ores, and paints.The cylinder is filled with a grinding The working principle of ball mill Meetyou Carbide,22 May. The ball mill consists of a metal cylinder and a ball. The working principle is that when the cylinder is rotated, the grinding body (ball) and the object to be polished (material) installed in the cylinder are rotated by the cylinder under the action of friction and centrifugal force. At a certain height, it will automatically
