BondWork Index TestBall Mill.US$ 13,800. The FCBondWork Index TestBall Millwas designed by F. C.Bondfor use in determining theBondIndex, 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’sMethod of Crushing and Grinding for determination of theBondIndex is included with each mill
Bond Ball MillGrindability Test. The test determines theBond Ball MillWork Index which is used withBond’sThird Theory of Comminution to calculate net power requirements*. Various correction factors may have to be applied. W = Wi (10/√P – 10/√F) Where W = Net power consumption in kWh/t
Ball MillDesign. A survey of Australian processing plants revealed a maximumball milldiameter of 5.24 meters and length of 8.84 meters (Morrell, 1996). Autogenousmillsrange up to 12 meters in diameter. The length-to-diameter ratios in the previous table are for normal applications. For primary grinding, the ratio could vary between 1:1and 1.8:1
Here is the old Allis-ChalmersBondWork Index Grindability Test Procedure. The standard feed is prepared by stage crushing to all passing a 6 mesh sieve, but finer feed can be used when necessary. It is screen analyzed and packed by shaking in a 1000-cc graduated cylinder, and the weight of 700 cc is placed in themilland ground dry at 250 per cent circulating load. Themillis 12 in. x 12
This Grindability Test orBond Ball Mill Work Index Procedureis used to determine theBondWork Index of minus six mesh or finer feed ore samples. These equation application methods are used to process <1/2″ ore samples in aBall Millusing a standardballcharge. Below describes in general terms theBond Work Index Procedureused by a Professional Metallurgical Testing Laboratory. If you
Theball millwork index laboratory 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 millwork index (Wi B or BWi). The work index calculations across a narrow size range are conducted using the appropriate laboratory work index determination for the material size of interest, or by …
The Bond ball mill work index is one of the most commonly used grindability tests in mining, and is often referred to as the Bond 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
