Abstract The Ball mill is one of the most important equipment in the world of chemical engineering. It is used in grinding materials like ores, chemicals, etc. The types of ball mills batch ball mill and continuous ball mill with different grinding media and different design depend on the nature of the input material and the nature of the output which I need.
products. Development of material for prototype liners in ball mills uses white cast iron material through a casting process. This development aims to make white cast iron material for ball mill liners which have physical and mechanical properties in the form of high impact and hardness needed to be able to produce domestically.
by design limits for maximum separation force, torque, Hertzian pressure etc, but these criteria are valid only under so called normal rolling conditions and even these change continuously with progressive wear in the contact zone. Besides normal rolling conditions - a stable, theoretical assumption - mills experience many different
with any other ball mills. This is the ideal mill for mechanical activation and alloying. The main applica-tions are in the field of materials research and, of course, wherever a powerful, innovative planetary mill is required. When particles 10 mm are fed in, a final fineness up to 0.1 m can be achieved.
With mechanical ball mills, material is discharged mechanically through a discharging box. The material is usually further conveyed to a dynamic separator, which together with the mill forms a mechanical ball mill grinding plant. These grinding plants are used to comminute relatively dry materials to

Abstract Processing in planetary ball mills is well suited to a large number of applications because they are easy to operate and versatile, grinding faster than other mills. Research related to planetary mills are mainly about the process evaluation, and there are few studies on the mechanical design
Sorrentino.19 In particular they classify the ball mills in two groups depending on their operation mode direct and indirect milling. In the rst case rollers or mechanical sha s directly act on the particles and transfer the kinetic energy. In the second case the kinetic energy is rstly transferred to the mill body and then to the grinding medium.
