Single particle impact breakage characteristics of clinkers related to mineral composition and grindability

Single particle impact breakage characteristics of clinkers from different plants were determined by the drop-weight technique. impact breakage distribution parameter (t(10)) defined by Narayanan INarayanan, S.S., Whiten, W.J., 1983. Breakage characteristics for ores for ball mill modelling. In: Proceeding of the Australasian Institute of Mining and Metallurgy, vol. 286, pp. 31-39.] was used to characterise the breakage distributions of different clinkers based on the specific comminution energy. The single particle impact breakage resistance parameter as represented by A.b [Man, Y.T., 2000. A model based scale-up procedure for wet, overflow ball mills. Ph.D. Thesis, Department of Mining, Minerals and Materials Engineering, The University of Queensland) based on the model parameters of the well known E-cs-t(10) relationship given by Leung [Leung, K., 1987. An energy-based ore specific model for autogeneous and semi-autogeneous grinding. Ph.D. Thesis, The University of Queensland, JKMRC] was correlated with the standard bond index number, belite and alite mineral amounts. (C) 2009 Published by Elsevier Ltd.
