and the clinker Bond work index w i(kWh/short ton). The equation was connected with a previously proposed model giving the specific grinding energy Eas a function of the Bond work index w i, the size reduction ratio R = D f/d 80, and the d 80 size of the product. From the procedure developed, it is possible to correlate the cement fineness F
This enables a more objec- tive identification of the energy required for grinding in the case when, for a certain grinding-product size, we do not dispose of the appropriate work-index value established by experiments. 46 REFERENCES Bond, F.C., 1961.

Hukki (1962) evaluated these energy-size relationships stating that each of Rittinger, Kick and Bond theories might be applicable for different narrow size ranges. Kick's equation is applicable for crushing, Rittinger's equation may be used for finer grinding, and Bond's equation is applicable in the conventional milling range.
