The ability to simulate the Bond work index test also allows examination of truncated ball mill feed size distributions on the work index. For grinding circuits where the feed to a ball mill is sent directly to the classifier and the cyclone underflow feeds the ball mill (see Figure 3.10), a question arises as to whether this practice will alter the ball mill work index (BW i) of the material
The 8 Zone composite is characterized by a moderately altered pyroxenite host rock cut by swarms of millimeter-scale quartz veins. Overall, the samples tested exhibited soft to moderate hardness with Bond ball mill work index values, at P 80 of 106 microns, ranging from 9.7 for the 8 Zone composite, to 17.1 in the strongly silicified Austin
Bond work index value of these components mixtures is greater than the Bond work in-dex of harder components, clinker. Oner (2000) have conducted a research of clinker and blast furnace slag mixture Bond Work Index in different mass propor-tions. He found out that these values are always lower than the Bond Index obtained
A Bond Ball Mill Work Index may also be used in the simulation and optimisation of existing mill(s) and the associated grinding circuit(s). Sample requirements: A minimum of 8 kg of material crushed to nominally minus 10 mm is preferred. JKTech would stage crush the sample to minus 3.35 mm, as required for the Bond Ball Mill Work Index test feed.
An alternative mill ball charge is proposed that closely approximates Bond''s original total ball mass, number of balls and ball surface area. Results of 30 Bond Work index tests of six pure materials (calcite, magnesite, labradorite (feldspar), quartz, andalusite and glass) using closing screen apertures (P 1) values of 500, 250, 125, 90 and 63

Work Index And Crushing Index For Quartz Definitions. Calculating crushing constant using bonds law bond work index formula-equationee this useful summary table of bond work index by mineralsor any circuit, whether a crushing circuit, a rod mill, or a closed ball mill circuit, the work index always means the equivalent amount of energy to
Where, WioACTis the Actual Operating Bond Work Index (kWh/t), W is the specific energy input (kWh/t), P80 is the 80% passing size of product (µm), and F80 is the 80% passing size of circuit feed (µm). 2. Calculate the Standard Circuit Bond Work Index (WiSTD) for the material being processed (equation 3). Wtotal
Apr 29, 2018 The Bond Ball Mill Work index test, first developed by Fred Bond in 1952, is the industry standard for sizing mills and measures the resistance of an ore to grinding. The Work Index can be used to determine the power required for closed circuit ball milling.
