Bond Work Index Test Ball Mill. US$ 13,800. The FCBond Work Index Test Ball Millwas designed by F. C.Bondfor use in determining theBond Index, a measure of grindability and power required for grinding applications. The FCBond Millsare used in laboratories throughout the world. A copy of Fred C.Bond’s Method of Crushing and Grinding for determination of theBond Indexis included with each mill.
Theball mill work indexlaboratory test is conducted by grinding an ore sample prepared to 100% passing 3.36 mm (6 mesh) to product size in the range of 45-150 µm (325-100 mesh), thus determining theball mill work index(Wi B or BWi). Thework indexcalculations across a narrow size range are conducted using the appropriate laboratorywork indexdetermination for the material size of interest, or by …Read more +
TheBond ball mill work indexis one of the most commonly used grindability tests in mining, and is often referred to as theBond work index. The test is a 'locked-cycle' test where ground product is removed from test cycles and replaced by fresh feed. The test much achieve a steady-state before completion.Read more +
The grinding jar for the Bond Index Rod Mill is 12″ x 24″ in size and has a wave-shaped design. At least 15 to 20 kg sample material is required to simulate a closed grinding circuit in aballorrod mill. TheRod Mill Work Index(RWI) is used for particle size determination in a size range from 25 mm down to 2.1 mm whereasBall Mill Work Index(BWI) is used for the range from 2.1 mm down to 100 µm.
