The effect of mill speed on kinetic breakage parameters of ...
Aug 01, 2004 Abstract. In this study, the effect of mill speed was investigated on the limestone and the clinker samples of Göltaş Cement Factory (Isparta, Turkey) at batch grinding conditions based on a kinetic model. For this purpose, first, six different monosize fractions were carried out between 0.850 and 0.106 mm formed by a two-sieve series.
