Pressure Grinding Temperature

pressure grinding temperature - hotelhengelsport.nl

From the temperature curves, it can be seen that the temperature in dry grinding was about 160 176;C, and that in wet grinding was below 70 176;C. Although the temperature in dry grinding is higher than that in wet grinding, the temperatures are far below the temperature for the formation of glassy phases.
