Crushing mill work index is used in the SAGMILLING Bond/Barratt specific energy consumption model. The work index is used to calculate the energy requirement to break rocks in the coarse size range, from >100 mm down to about 10 mm - 20 mm.

Using calculated value N it is possible to calculate parameter G (g/rev.): 𝐺=𝑍 = 𝑀 3,5 ∙𝑋 . (7) In this way, obtained values for second, third and fourth grinding are G 2e, G 3e and G 4e. During the execution of the standard Bond procedure on over thirty samples of
The energy required per unit mass to grind limestone particles of very large size to 100 μm is 12.7 kWh/ton. An estimate (using Bond''s law) of the energy to grind the particles from a very large size to 50 μm is (A) 6.35 kWh/ton (B) 9.0 kWh/ton (C) 18 kWh/ton (D) 25
An alternative approach to determine the effect of closing screen size on the Bond ball mill work index (BW i), in the absence of extensive test work, is to use computer simulation. The batch grinding process has been modelled using the size–mass balance approach (Austin [37], Chapter 11 ) and if we can do this, then we can effectively simulate the Bond ball mill work index test.
By this single test one judge that whether Concreting has been done properly or not. Concrete compressive strength for general construction varies from 15 MPa (2200 psi) to 30 MPa (4400 psi) and higher in commercial and industrial structures. Compressive strength of concrete depends on many factors such as water-cement ratio, cement strength ...

Application of CAPM model We will see a few examples of CAPM which is most often used to determine what the fair price of an investment should be. When we calculate the risky asset''s rate of return using CAPM, then that rate can also be used to discount the investment''s future cash flows to their present value and finally arrive at the investment''s fair price.

The Bond Ball Mill Work Index (BBWi) test is carried out in a standardised ball mill with a pre-defined media and ore charge. 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 passing size of <3.35 mm.
