2015-6-16 Sizing a crusher can be done reliably calculated thanks to the Impact/Crushing Work Index and the testwork research done by Fred Chester Bond

The Bond Low-Energy Impact test can be used to determine the Crusher Work index (CWi), also known as the Impact Work Index. The test determines the impact energy at which a specimen fails and allows approximation of net power requirements for sizing crushers. The open and closed sized settings for given product sizes can also be determined.

2021-7-9 The Bond Crushing Work Index (CWI) describes the competency of the ore at larger particle sizes. It is used for the calculation of the actual crusher power

Bond Work Index Equation For Jaw Crusher. Bond Work Index Formula-Equation Basic EquationsSize Distribution and Exposure RatioEquations For Work Index VariationsWork Index and Crack Energy The basic work index equation is:W = 10 Wi/√P 10 Wi/√F(1)where W is the work input required in kilowatt hours per short ton to grind from 80% passing F microns to 80% passing P microns, and Wi is the

Compressive Strength. Figure 7 shows an attempt to relate the sum of all Bond Work Indices to the UCS. The Y-axis on this graph measures Wi C+Wi RM+Wi BM. The sum of the Bond Work Indices fails to show a relationship to UCS. A related graph plotted UCS versus the total comminution energy required to grind a 100 mm rock to 200 microns.

The Bond work index (Bond, 1960) is based on Bond’s law, which states that the energy consumed is proportional to the 1.5 power of particle size rather than the square of Rittinger’s law. Accordingly, the energy consumed in reducing the particle size from x F to

The sum of the Bond Work Indices fails to show a relationship to UCS. A related graph plotted UCS versus the total comminution energy required to grind a 100 mm rock to 200 microns.

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

2008-8-1 (1) W Bond = C Bond × 1 p 80-1 f 80 (2) W Kick =-C Kick ln p 80 f 80 (3) W Rittinger = C Ritt × 1 p 80-1 f 80. Here, W is the energy consumption per tonne of material crushed, C Bond is the so-called work index of the rock, obtained in a test. C Kick and C Ritt are the corresponding work indices in Kick’s and Rittinger’s formulae

2021-3-4 Powder Factors were estimated from their Bond ball work indices. The abrasive indices were also determined by using the JK method. Bond ball work index test results obtained for PF 0.72, PF 0.88 and PF 0.96 were 14.2 kWh/t, 13.9 kWh/t and 13.7 kWh/t respectively. The energy consumed and cost incurred on size reduction of a

2021-5-27 Cost of Living Indices: Why Use Them? One technical issue that comes up when looking at consumer price indices is that the concept of a “cost of living index” comes up. This is a technical definition, as opposed to the vaguely defined notion of a “cost of living” that is used in popular discussion.
