Sizing a crusher can be done reliably calculated thanks to the Impact/Crushing Work Index and the testwork research done by Fred Chester Bond and his 1952 paper. According to Bond’s Third Theory of Comminution, the work/energy input is proportional to the new crack tip length created during particle breakage and equivalent to the work represented by the product the feed.

The Bond crushing work index test (sometimes called the "impact work index" test) is noisy, and the difference you observed is perfectly reasonable. The paper by Angove & Dunne (1997) reports a standard deviation in crushing work index tests across laboratories as 4.5.

bonds equation crushing Mine Equipments. an overview of the small-scale tests available to characterize ore The Bond tests are typically run for a minimum of seven cycles, while the sample is stage-crushed to Ѕ” and the test is run under a 100% circulating load.The rod mill work index is computed with an equation very similar to that of the ball.

The Bond low-energy impact crushing work index (more informally, the Bond crushing work index) is not as common as the Bond ball mill work 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.

Rock Crushing Theory and Formula using Kick Rittinger's Law. Metallurgical ContentThe Two Laws:What about Bond?Rittinger’s Law:The Crushing-Surface Diagram: Rittinger’s theory and law of the energy expended in crushing of rock is that the work of crushing is proportional to the reduction in diameter; or, as I have more fully expressed it: “The work done in crushing is proportional to the

Calculations involving Bond’s work index are generally divided into steps with a different Wi determination for each size class. The low energy crushing work index laboratory test is conducted on ore specimens larger than 50 mm, determining the crushing work index (Wi C, CWi or IWi (impact work

The Bond ball mill work index test is thought to be additive because of its units of energy; nevertheless, experimental blending results show a non-additive behavior. The SPI(R) value is known not to be an additive parameter, however errors introduced by block kriging are not thought to be significant .

11 Crushing and classification Estimates vary, but it is generally accepted that of all the energy used in the World something like between 1 and 10% is in comminution, i.e. the processes of crushing, grinding, milling, micronising, etc. Changing the size of the particles by crushing

parameter ta and crusher model energy matrices, the SMC Test ® can be used to conduct AG/SAG mill and crusher circuit simulations through the use of JKSimMet. Independent of this it can be used in power-based calculations, which in conjunction with the Bond ball work index test, enable the prediction of the specific energy of comminution circuits

A mill is a device that breaks solid materials into smaller pieces by grinding, crushing, or cutting. Such comminution is an important unit operation in many processes.There are many different types of mills and many types of materials processed in them. Historically mills were powered by hand (e.g., via a hand crank), working animal (e.g., horse mill), wind or water ().

Bond Work Index and Drop Weight Tests are more re sample, resources and time. However, the PLI value (Is 50 in MPa) can be correlated to the Drop Weight test parameters (A & b) and the Bond Work Index (BW i). The Drop Weight and Bond Work Index parameters are required to model the crushing and grinding circuits. Therefore, the use of the
