Finite element analysis of high-pressure grinding rolls for crack prediction to determine safe working conditions

High Pressure Grinding Rolls - HPGR is a relatively new technology first implemented in Europe into Cement Industry and later incorporated into Mineral industry in the late 20th century as replacement to conventional mills like rod and ball mills due to the higher efficiencies offered by them in comminuting the material fed to the mill. These are heavy duty machines designed to operate for 60–100 thousand hours, hence making millions of...
