Bond, F.C., Crushing and Grinding Calculations, British Chemical Engineering, 6, 378-391, 543-548, (1960) For wet grinding it is found that a mill pulls the same power for a 10% increase in ball load, other factors being constant.

The Bond ball mill work index (BWI) is computed with an equation very similar to that of the rod mill test (Bond, 1960). The world has historically relied widely on the ball mill work index for the design and analysis of ball mill circuits, even for those that treat AG/SAG mill or HPGR circuit products, which have a nonstandard particle size ...

Fine grinding or milling reduces the particle size down to as low as 1.0 micrometer (µm) (4 x 10-5in.) in diameter. Ball mills are the most commonly used piece of equipment for milling. However, vibratory mills, attrition mills, and fluid energy mills also are used. Crushing and grinding typically are dry processes; milling may be a wet or dry ...

Size reduction by crushing has a size limitation for the final products. If further reduction is required, below 5- 20mm, grinding processes should be used. Grinding is a powdering or pulverizing process using the rock mechanical forces of impaction and attrition. The two main objectives for a grinding process are:

The standard Bond Ball Mill Work Index test procedure is firstly to stage crush the feed to minus 3.35mm, and size a representative sample. The test then involves a series of batch grinds in a standard Bond mill. A Bond mill is 0.305m by 0.305m, with rounded corners, a …

f c where K K is called Kick's constant and f c is called the crushing strength of the material, we have: dE/dL = -K K f c L 1 which, on integration gives: E = K K f c ln(L 1 /L 2) (11.2) Equation (11.2) is a statement of Kick's Law. It implies that the specific energy required to

Bond's Law: The work required to form particles from very large feed is proportional to the square root of the surface-to-volume ratio. E = K B f c [ (1/L 2) 1/2 - (1/L 1) 1/2] Rittinger's Law — The energy required for reduction in particle size of a solid is directly proportional to the increase in surface area. E = K R f c (1/L 2 – 1/L 1)

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 …

The Bond method allows for quantification and com-parison of relative energy efficiencies of most industrial comminution circuits. It is an essential tool for managing the important business (cost) of grinding. For early analyses of plant grinding efficiency issues, see Bond (1957, 1960). 5.SCOPE This Bond Efficiency determination applies to most
