To use this equation, a work index Wi is defined as the gross energy requirement in kilowatt-hours per ton of feed needed to reduce a very large feed to such a size that 80% of the product passes a 100-µm screen.

2016-3-11 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 surface exposed by the operation; or, better expressed for this purpose, the work done on a given mass of rock is proportional to the reciprocal of the

2013-7-15 See this useful summary Table of Bond Work Index by Minerals. For 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 reduce one ton of the ore from a very large size to 100 um. The sample was received crushed appropriately for the ball mill test.

2010-5-14 Rittinger’s and Kick’s laws Rittinger's law states that work required in crushing is proportional to the new surface created. In other words, crushing efficiency is constant and for a given machine and feed material is independent of the sizes of feed and product. Rittinger’s law is written as- P/ ṁ = Kr (1/Dsb 1/Dsa) Kick proposed another law based on stress analysis of plastic deformation within the

Bond's law. [ ′bänz ′lȯ] (mechanical engineering) A statement that relates the work required for the crushing of solid materials (for example, rocks and ore) to the product size and surface area and the lengths of cracks formed. Also known as Bond's third theory.

bonds law for crushing La Bruschetteria. CHE F313: Separation Processes II Bond's Law • A somewhat more realistic method of estimating the power required for crushing and grinding was proposed by Bond in 1952 • Bond postulated that the work required to form particles of size D p from very large feed is proportional to the square root of the surface to volume ratio of theRittinger's, Kick's

2021-5-14 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 creates many important industrial products.

The Bond work index is not solely a material constant but is influenced by the grinding conditions. For example, the finer the grind size desired, the higher is the kWh/t required to grind to that size. Magdalinovic [38] measured the Bond work index of three ore types using different test screen sizes. He produced a correlation between the mass of test screen undersize per revolution, G, and

The Bond Work Index is material specific and is obtained from laboratory crushing tests on the feed material. Hard and brittle materials have a work index in the range 4 × 10 4 − 8 × 10 4 J/kg. Bond’s law holds reasonably well for a variety of materials undergoing coarse, medium and fine size reduction. (Eq. 14.3a) can also be reduced to

The length of the pendulum was 413 mm and the mass of hammers is 13.6 kg each. The sample was completely crushed when the initial position of the pendulums made an angle of 30° with the vertical.
