Abstract

Breakage behaviors and strength bump off traits of coal are at once influenced with the aid of properties, such as particle size, ash content material or density. It is vital to mannequin these outcomes and behavior quantitative evaluation. In this study, samples of four particle sizes × 4 ash contents have been floor in a Hardgrove mill for 9 electricity levels, respectively. Breakage price of particles in the pinnacle measurement and t10 had been decided and outcomes of coal homes on two parameters have been additionally discussed. Though the relation between fed on energies and t10 of every pattern can be described with the aid of classical breakage model, experimental records of all samples have been scatter. In this case, particle dimension and ash content material had been modelled into breakage equation in exponential term, particularly t10 = A × (1 − e−b∙x∙Ecs/eYa). This modified mannequin gave appropriate becoming outcomes to experimental data.
