Definition of pulverization. "Pulverization" (comminution, crushing, grinding) is the process of applying an external force to a (solid) material of a certain size to destroy it and reduce it into pieces that are smaller than the original size. Pulverization has long been done for many materials, including ore, glass, ceramics, grains ...

The comminution process of High Pressure Grinding Rolls (HPGR) was discovered in the 1980s by the research work of the German Professor Schönert. Its main advantage is the high energy efficiency in comparison to ball mill grinding which has been the benchmark process in the cement industry by then (Schönert, 1988).
