For producing 200 mesh and 325 mesh commonly used lime powder, one of the main machine configurations for the grinding process is either the vertical lime grinding mill or the Raymond mill (pendulum grinding mill).. The …

Calcination is the practice of dehydrating gypsum into plaster or stucco through a batch or continuous process which includes heating the gypsum to evaporate the crystalline water. Typically, free water is removed in an initial process at approximately 45℃ and crystalline bound water is removed in a second process at 120-180℃.
