Analysis of temperature distributions in surface grinding ...

An analytical model was established to calculate the curve of temperature distributions in surface grinding with intermittent wheels. In order to predict the numbers of the pulses imposed on the fluctuating temperature profile, a new quantity, the dynamic number of wheel segments in the grinding zone, was defined. The temperatures at the grinding zone were measured by using a foil thermocouple.

How Temperature Affect Grinding Efficiency. 24-10-2017· In autogenous milling, temperature can significantly influence the grinding efficiency, particularly if the temperature falls below about 10°C. these efficiency changes can be reduced by preventing recycle water from becoming chilled, and by thawing frozen rock before grinding.

Grinding Sparks in Explosive Environments | TFT Pneumatic

Whereas cutting and grinding create sparks by particle removal at high speed that creates frictional heat, welding raises the temperature of a localized area to a level where the material melts. The use of high-temperature gases and electrical arcs in welding means that as no mechanical energy has imparted the distance the sparks travel is reduced.
