Bond Ball Mill Work Index Test (BBMWI) is a standard test for determining the Ball Mill Work Index of a sample of ore. The BBMWI is a measure of the resistance of the material to crushing and grinding. It can be used to determine the grinding power required for a given throughput for material under ball mill grinding conditions.
A grinding mill (F305 mm 305 mm) was used for the Bond ball mill work index test [18–21]. This ball mill was ﬁlled with 285 steel balls (total weight of kg) at an operation speed of 70 rpm.
ASTM E38212, Standard Test Method for Determination of Crushing Strength of Iron Ore Pellets, ASTM International, West Conshohocken, PA, 2012, Back to Top
The grindability of an ore in the process of mineral dressing can be determined by use of the Bond work index (W i).This index is determined on a laboratoryscale using a Bond ballmill and by simulating dry grinding in a closed circuit until the 250% circulating load has been obtained.
• The dynamic swelling of iron ore pellets in a simulated blast furnace atmosphere is considerably more restrained than the corresponding static swelling. Thus, the reduction swelling behaviour of iron ore pellets should preferably be studied DYNAMICALLY under simulated blast furnace conditions to obtain the most realistic results.

Iron ore pellets and Pelletizing processes. The disc is an inclined pan of around 5 to meters diameter rotating at around 6 to 8 rpm. The inclination of disc is around 45 Deg. and it can be adjusted in the offline between 45 deg. to 49 deg. The pre wetted mix is fed into the disc at a controlled rate.
Apr 29, 2015· 1)In the determination of iron in an ore, the ore (mostly Fe2O3) is first dissolved in HCl(aq). A slight excess of Sn2+ is added to reduce Fe3+ to Fe2+. Write the net ionic equation for the redox reaction. 2)The excess Sn2+ is removed by adding the mercuric ion, Hg2+(aq), forming the mercurous ion, Hg22+.
Determination of Iron in an Iron Supplement Pill Sample Preparation* Select one of the "iron supplement" brands. Record in your notebook the brand name and the stated amount of iron in each tablet. One tablet will be shared among the four students in the .

to for Crushability Work Index (CWi = +/ ) and Abrasion Index (Ai = ) determination. The results suggest that Blötberget "can be considered a typical iron ore, which is crushed easily but very abrasive". It is therefore considered that attention must be paid to the generation of large amounts of fines during crushing. The Bond Rod Mill Work Index was determined by GTK Mintec to be .
kg of minus 3⁄4" plus 1⁄2" ore. This can normally be obtained by taking 5 kg of ore crushed to minus 3⁄4" and screening at 1⁄2". SGS's team of experienced engineers will conduct the Abrasion Test in combination with other benchscale tests and circuit simulation.
In order to determine Bond work index of a material, firstly, it must be prepared according to the Bond standard method. The kinetic method uses the same mill operating under the same conditions as those in Bond standard procedure, except for the grinding time, revolution numbers, sample amount and sieving procedure.
Nov 28, 2017· Goldman Sees Iron Ore Sinking Back to 50. At the same time, supplies of iron ore are expected to increase in 2018. Exports from Australia, the top shipper, will rise to 872 million tons in 2018 and 895 million in 2019, while cargoes from Brazil gain to 403 million and 419 million, the department forecast in its latest quarterly study.
