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 ...
Size reduction. Zeki Berk, in Food Process Engineering and Technology, 2009. 6.3.3 Energy consumption. As a rule, size reduction operations are heavy in energy consumption (Loncin and Merson, 1979; Hassanpour et al., 2004).As an example, the cost of energy is the single largest item in the total cost of wheat milling. Milling of one bushel (approx. 27 …
In the Rittinger equation, Rittinger's constant (k R) is independent of the size of ground particles, yet we noted large variations in k R among similar particle size ranges. In this research, the dependence of k R on the physical structure and chemical composition of a number of woody materials was explored. Branches from two softwood ...
