The final stage in iron ore processing is ironmaking, where the iron ore is transformed into molten iron through a process called reduction. The most common method of ironmaking is the blast furnace route. In a blast furnace, iron ore, coke (carbon), and fluxes (limestone or dolomite) are loaded into the furnace from the top.
The sample of coarse iron ore was characterized in laboratory tests carried out in a small batch ball mill. Selection and breakage function parameters were determined from the laboratory tests.

Ball Mills. Ball mills have been the primary piece of machinery in traditional hard rock grinding circuits for 100+ years. They are proven workhorses, with discharge mesh sizes from ~40M to <200M. Use of a ball mill is the best choice when long term, stationary milling is justified by an operation. ... We bought a turn-key ore processing system ...
The ball mill is a rotating cylindrical vessel with grinding media inside, which is responsible for breaking the ore particles. Grinding media play an important role in the comminution of mineral ores in these mills. This work reviews the application of balls in mineral processing as a function of the materials used to manufacture them and the …
A comparison between breakage (a) and selection (b) functions fitted for all the tests is presented in Fig. 2.Itabirite iron ore exhibited more aggressive breakage and selection functions, consistent with its lower competence as showed by its BWI (Section 2.1).Since the current model investigated does not account for changes in breakage rate …
The vertical stirred mill is vertically installed, and gravity works in the grinding process. With the advantages of high grinding efficiency and less area occupation, it is widely used in the regrinding, fine grinding, and ultrafine grinding process of such metal mines as iron ore, copper ore, lead-zinc, and such nonmetallic mineral industries as …
For the purposes of this example, we will hypothesize that the the crushing index of the hard ore with the increased energy input of 1.54 kw/t reduces the ball mill feed size to 6,500 micrometers. As a result, the mill output will increase with this reduced size to approximately 77,000 tons per day.

Ball mills can be as small as lab-scale mills or as large as industrial mills with a diameter of up to 8 m. The mill's capacity is dictated by its volume. The volume depends on both diameter and length. Generally, the length-to-diameter ratio of the mill, known as the L/D ratio, is between 0.5 and 3. Shorter mills are used for crushing coarse ...
