How to process gypsum
Making Gypsum Board Gypsum Association
To produce gypsum board, crushed natural gypsum or synthetic gypsum is heated or calcined to dehydrate the feedstock Next the calcined gypsum is mixed with water and additives to form a Gypsum processing can be divided into three basic steps: (1) rock preparation, (2) calcining, and (3) formulating and manufacturing This is illustrated graphically with the flow chart in Figure 1 The specifics of each step will vary with the Infrastructure and Construction Materials Guide — wallboard, gypsum must be partially dehydrated or calcined to produce calcium sulfate hemihydrate (CaSO4 ½H 2O), commonly called stucco A flow diagram for a typical gypsum process producing both crude and finished gypsum products is shown in Figure 11161 In this process gypsum is crushed, dried, ground, and calcined1116 Gypsum Manufacturing US EPA2023年5月15日 According to Lavoisier and Le Chatelier, 9 the reaction is a process of dissolving hemihydrate to create a super saturated solution of gypsum, from which gypsum is formed This is possible due to the lower solubility of gypsum compared to hemihydrate This theory is proven by Figure 4a 4i and it shows why gypsum can act as an acceleratorUnderstanding gypsum in 3 diagrams
