Beschreibung
Zusammenfassung:	The invention discloses a process for producing a thistle board by using desulphurization gypsum and natural gypsum, which comprises three process steps of milling, pulping and board making. The method uses the desulphurization gypsum and the natural gypsum according to certain proportion, reduces energy consumption of a manufacturing technique of the natural gypsum, effectively adjusts the grain composition of building gypsum powder, reduces the resource consumption while ensuring the normal production and the product quality of the thistle board, protects natural minerals and the environment, and achieves better effect of comprehensive utilization of resources.
