Sizing a crusher can be done reliably calculated thanks to the Impact/Crushing Work Index and the test research done by Fred Chester Bond and his 1952 . According to Bond’s Third Theory of Comminution, the /energy input is proportional to the new crack tip length created during particle breakage and equivalent to the represented by the product the feed. A crude test
The Bond low-energy impact crushing index (more informally, the Bond crushing index) is not as common as the Bond ball mill index, and it is a notoriously noisy test.. The test is a 'per-specimen' test where individual specimens of prepared rock are hand-picked by the test operator and placed into the apparatus.
Calculations involving Bond’s index are generally divided into steps with a different Wi determination for each size class. The low energy crushing index oratory test is conducted on ore specimens larger than 50 mm, determining the crushing index (Wi C, CWi or IWi (impact index)).

The Bond index is a measure of ore resistance to crushing and grinding and is determined using the Bond grindability test. Its value constitutes ore characteristic and is used for industrial
Figure 1 displays the measured crushing Work Index versus UCS for all mines in the data set. FIGURE 1: BOND CRUSHING WORK INDEX v. UNCONFINED COMPRESSIVE STRENGTH 0 100 200 300 400 UCS, MPa 10 20 30 40 50 WiC (metric) The scatter of the points in Figure 1 indicates no correlation between crushing index and UCS.

The Work Index calculated from the testing can be used in the design and analysis of ball mill circuits. The test requires a minimum of 10kg of sample that has been stage-crushed to 100% passing size of <3.35 mm. Any screen size below 600µm can be used for the test depending on your requirements.
Ball Mill Bond Work Index For Limestone Gold Ore Crusher. Mobile Cone Crushing Plant; bond ball mill index crushing and The Mining Machine is custom designed to reduce your operating costs and
Relation of Bond rod mill index and crushing index. Similar to the ball mill index, the rod mill index is a tumbling test that includes both attrition and abrasion breakage mechanisms. Unlike the ball mill index, the size of the feed to a rod mill test (10 mm–12 mm) is closer to the size of the crushing test. Get P
Chapter 3 Particle Technology (Size Reduction) Kick’s law: the required for crushing a given mass of material is constant for the same reduction ratio, 3.2.2 Bond crushing law and index.
