What is HPGR Modelling for Mineral Liberation about?

The document presents a model for high-pressure grinding rolls (HPGR) that incorporates mineral liberation. The model generalizes the traditional population balance approach by linking it to energy dissipation, residence time distribution, and a mineral liberation model. The HPGR model calculates throughput, power, and particle size distribution based on operating parameters. It considers both single particle breakage and inter-particle comminution in the bed. The model can be used to optimize plant design
