Dehydrate gypsum is the plaster in nature. After calcination process gypsum dehydrate transform to hemihydrate, AII anhydride (dry plaster) and AIII soluble (unstable gypsum). Hemihydrate, in other words named as stucco is the plaster calcined by losing 1,5 moles of the 2 moles of water. AII Anhydride; (anhydrite) lost all 2 moles of water in

Milling is among the most energy-consuming technological stages of copper ore processing. It is performed in mills, which are machines of high rotational masses. The start of a mill filled to capacity requires appropriate solutions that mitigate the overloading. One method for increasing the energy efficiency of ball mills is to optimize their drive systems.
