energy required to grind gypsum rock

Jul 12, 2016 Since comminution involves production of new surface, the energy required to produce a given amount of surface can be reduced by decreasing the solid surface energy. This mechanism was believed intuitively to be responsible for the improved efficiency resulting from additives in rock drilling, according to Rehbinder and Kalinkovaskaya (1932).

The UK is largely self-sufficient in gypsum. The material can be found in seams in the Pennines and the Midlands, but the biggest source of extraction is in East Sussex where mining extracts some 100,000 tonnes of gypsum a year from 100 m below the High Weald. The mined rock is reduced to powder through a process of crushing and grinding.
