Tubular Ball Mills - ScienceDirect
2016-1-1 Thus, the medium could be steel or cast iron balls when the mill is designated as a ball mill, or it could be steel rods where the mill is known as a rod mill. When no grinding medium is charged it is known as an autogenous mill. In this chapter, we initially discuss the design and operation of tubular mills followed by ball mills.
