Template:Model theory (Text, Ball Mill, Perfect Mixing, Appearance)

The appearance function describes the mass-by-size distribution of progeny particles resulting from the breakage of parent particles.

The appearance function may be specified for a particular ore. Alternatively, the default Broadbent-Callcott appearance function may be used, which is defined as:

$A_{ij}={\frac {1-\exp \left(-{\dfrac {d_{i}}{d_{j}}}\right)}{1-\exp(-1)}}$

where Failed to parse (SVG (MathML can be enabled via browser plugin): Invalid response ("Math extension cannot connect to Restbase.") from server "https://wikimedia.org/api/rest_v1/":): {\displaystyle d_i} is the breakage product particle size and $d_{j}$ is the original particle size.
