Methods for determination of breakage distribution

The distribution of primary breakage products in laboratory mills can be estimated by batch grinding for short times. Three methods are given for manipulating the data, the second and third methods correcting for secondary breakage. Method III is the most accurate, but since it uses the specific rates of breakage of the various sizes in the ...

De data base shows the results of a new methodology to determine the breakage distribution function parameters to be used in High pressure grinding rolls modelling. The piston die test tries to simulate a high pressure enviroment, thus the resulted particle size distribution can be normalized to describe a breakage mechanism. Furthermore, one example of how to obtain the breakage function ...
