The Kick and Rittinger laws are special cases of one form, and Bonds law is a special case of the other. Thus it is possible for Rittinger's and Bond's laws to apply to the same set of data. Recommended articles. References (6) Size reduction; F.C. Bond. AIME Mining Trans. (1960)

There are many experimental results in favour of the theory of Rittinger [], scant evidence for the theory of Kick [] and the evidence for the third theory is provided by Bond himself [].Generally, the size range covered by these experiments is also relatively narrow [].Thus, it is strongly suggested that all the comminution theories are actually …

Specific grinding energy (J/g) was correlated with size parameters of three popular industrial equations: Kick, Rittinger, and Bond. All three equations fitted to the experimental data linearly but the best fitted lines did not go through the origin, i.e. the fitted lines had a slope and intercept. Rittinger equation had the best fit, followed ...
