Assessment and modelling of quaternary and quinary HPGR
The complexity degree of a mining plant's comminution circuit is critical for allowing the processing of low-grade iron ore deposits. Considering that the comminution stage is responsible for most of the energy consumption in a mineral processing plant, the pursuit of energy-efficient technologies is a major challenge of the mining industry. The High Pressure Grinding Rolls (HPGR) have been

Mill (grinding)
A mill is a device that breaks solid materials into smaller pieces by grinding, crushing, or cutting. Such comminution is an important unit operation in many processes. There are many different types of mills and many types of materials processed in them. Historically mills were powered by hand or by animals (e.g., via a hand crank), working
