3 size reduction - SlideShare

21-09-2019· Tumbling mills (Rod mill) In a rod mill, much of the reduction is done by rolling compression and by attrition as the rods slide downward and roll over one another. The grinding rods are usually steel, 25 to 125 mm (1 to 5 in.) in diameter, with several sizes present at all times in any given mill. The rods extend the full length of the mill. Rod mills are intermediate grinders, reducing a 20

Rod Mills - 911Metallurgist

A rod mill uses steel rods as the grinding media in tumbling mills is an efficient means to feed ball mills a product finer than could be made in a crusher but coarser than could be made in a ball mill. The principal use for rod mills, which were invented to make ball mill feed in a wet-grinding rod mill-ball mill circuit. Rod mills came into use in the United States beginning in 1900s and
