Regarding heat transfer in dry surface grinding, simple asymptotic expressions of the maximum temperature for large Peclet numbers are derived. For this purpose, we consider the most common heat flux profiles reported in the literature, such as constant, linear, triangular, and parabolic. In the constant case, we provide a refinement of the expression given in the literature.

Diamond grinding wheels | Ensinger

The grinding rotor disperses the wet material into very fine particles and the fine particles are fluidised in the grinding chamber by temperature-controlled, hot gas coming in from the air heater. The hot air (or inert gas) can be heated up to 650 °C and as the wet product is dispersed, it is reduced in size in the bottom section of the dryer.
