Abstract

Three dimensional numerical simulations of particles motion in a given geometry pneumatic conveying system are conducted in order to obtain a better understanding of the attrition process A new and innovative procedure of implementing empirical comminution functions Kalman et al in Gran Mat 11253–266 2009 into DEMCFD simulations was used and modified The comminution functions include initial strength distribution selection function breakage function equivalence function and fatigue function The implementation involves converting the probability comminution functions into individual particle properties by a random method and then converting the velocity dependent comminution functions into strengthdependent ones The predictions of the numerical simulations are used to analyze the flow field characteristics and the size reduction process
