The α-high strength gypsum production has three technologies. They are the autoclave method, the semidry method and the hydrothermal method. Compared with the semidry method and the autoclave method, the most outstanding feature of the hydrothermal method is that the α-high strength gypsum produced in this method has higher dry compressive strength and dry bending strength than those of the other two methods. The α-high strength gypsum production line developed by Jiangsu Efful Science and Technology Co., Ltd also adopts the hydrothermal method. The α-high strength gypsum produced by Jiangsu Efful Science and Technology Co., Ltd has many advantages such as high strength, excellent surface smoothness after being molded etc. The mechanical performance index of the α-high strength gypsum exce...
β Gypsum Calcination Production LineTechnological ProcessPre-drying SystemThe pneumatic drying is adopted. It consists of the dry pipe, the cyclone separator and the bag-type dust remover. Calcination SystemThe fluidized calcinations method is adopted. Inside the equipment, the main steam pipe divergent coil pipe is used for heating, which takes full advantage of the heat source, saves energy, has a small range of temperature variation and is easy to control. Modification And Mixing SystemThe calcined gypsum powders are delivered to the modified mixer. Meanwhile, the modifier is added quantitatively through the mini-sized feeding machine. Initial setting time, final setting time, dry compressive strength, bending strength, expansion rate etc. of the modified β gypsum powder can m...
