With the development of the society and economy,nowadays the paper faced gypsum board production line is the professional equipment for producing the new decorated material.the principal working process are as follows:first,we take certain amount of hemihydrate gypsum powder,water and other additives,through the automatic measurement device and automatic conveying system,they will be conveyed into the mixer and changed to the gypsum slurry which will be scattered on continuous faced paper evenly.second,at the same time,with the continuous moving and vibrating,the slurry will gradually diffuse and even scattered.then the slurry will go into the forming machine and compound with top and bottom faced paper,by the process of extruding and forming,the slurry will be encased by the faced paper and the pulpous gypsum boards are formed.third,in the forming line,the wet solid paper faced gypsum board will be gradually formed after the process of recondition,natural coagulating,automatic cutting,etc,the wet gypsum board will be arranged according to the programmed control system..with the help of rollers,belt conveyor and overturner,they will quickly enter into the dryer.forth,the board will be strictly controlled in the seperate temprature zone of the dryer.because of the reaction of the starch,the board will be attached to faced pater,and then the dry gypsum board will form and exit from the dryer,moreover,after passing through the overturner and the folding device for the second time,the board will be cut into certain specification by saw.finally,the finished gypsum board will be conveyed to automatic sealing device and the stacker.
