grinding passes, higher surface temperature and smoother surface roughness is generated at the higher number of grinding passes for both the experiments. By the end of the thesis, grinding in wet operation, with lowest depth of cut (10 µm), minimum table speed (10 m/s) and higher grinding passes (2 passes) are recommended to grind. More

PM. Another control technique for phosphate rock dryers is use of the wet grinding process.
