After the second crushing machine, iron ore particles are moved to secondary crushing and the first ball mill grinding.
A mill is a device that breaks solid materials into smaller pieces by grinding, crushing, or cutting. Such comminution is an important unit operation in many processes. There are many different types of mills and many types of materials processed in them. Historically mills were powered by hand (e.g., via a hand crank),.
Ball mills. Ball mills are used for wet grinding iron ore, gold/copper ore, nickel ore and other ores, as well as lime/line for flue gas desulphurisation systems, coal and other raw materials. Wet mills are generally designed as overflow mills and are operated in open or closed grinding circuits.

Mar 28, 2015 . Ball mills are the principal means of fine grinding of iron ores. They are tumbling mills like the rod mills, but usually with a smaller length to diameter ratio which ranges up to 1.5. The grinding media is steel balls instead of rods. Grinding efficiency is greatly affected by the classification efficiency and the mill.
2.2.1 Grinding. Grinding is a sub-process of finely grinding ore in advance, such that the ground output can be physically separated into iron ore and impurities in the downstream sub-process. In many cases, an autogenous mill (AG mill) or a semi-autogenous mill (SAG mill) is used for the primary grinding, and a ball mill is.
