Calcining processes for natural and synthetic gypsum

The roller mill is a short-time calcining system. Both natural gypsum and mixtures of natural and synthetic raw materials can be ground, dried, calcined and classified in this kind of mill. Bundling several process steps results in highly efficient gypsum processing. Natural gypsum and up to 45% moist FGD gypsum can be fed into a roller mill.
