COMPARISON OF GYPSUM DEWATERING …
This paper discusses three technologies that are used by coal-fired power plants to dewater and dry gypsum. These are centrifuges, continuous belt filters (CBF) and continuous-indexing belt filters (CI-BF) and rotary vacuum filters.
Rotary Drum Vacuum Filters For Production Of Wallboard-Grade Gypsum
The operating performance results of the rotary drum vacuum filters at Coleson Cove are presented, proving the capability to produce wallboard quality gypsum filter cake with moisture content as low as 6%. Key aspects of the design and operation of the filters that make rotary drums a viable choice for dewatering are presented.
