Every 24 hours, around 180,000 tonnes of ore are fed into the six milling lines' autogenous grinding mills (AG mills), these are the largest grinding mills in the world. Each mill measures about 12 metres in diameter and has an internal volume of 1,220 cubic metres. As the AG mill turns, the ore crushes against itself and breaks apart.

A grinding mill is a unit operation designed to break Reducing Grinding Energy and Cost - Magnetite Iron Ore amount of feed to rod mill when grinding copper ore Most copper facilities use a combination of rod and ball mills to grind sulfide ore (Figures 1-6a and b).

or rod mills for further size reduction. Types of mill Different types of mill are in operation e.g. rod or ball mills, so called depending on the steel based media placed internally to assist the grinding process. If no media is used i.e. the tumbling ore itself causes breakdown then the mill is called autogenous grinding or AG.

Ball & Rod Mill Density – How Water Impacts Grinding. Density, if you recall is the ratio of ore to water and is measured as a percent of solids in the water. It will control the grind in two ways. It affects retention time and helps distribute the ore through-the mill so each piece of rock will come in contact with the surface of the rods.

A rod mill is an ore grinding mechanism that uses a number of loose steel rods within a rotating drum to provide its attrition or grinding action. An ore charge is added to the drum, and as it rotates, friction between the tumbling rods breaks the ore down into finer particles. Although similar in operation, a rod mill is often more effective ...

One stage rod mill grinding is therefore suitable for preparation of feed to gravimetric ore dressing methods, certain flotation processes with slime problems and magnetic cobbing. Rod mills are frequently used as primary mills to produce suitable feed to the second grinding stage. Rod mills have usually a length/diameter ratio of at least 1.4.
