gypsum powder production line With the development of gypsum industry, there is a large demand for quantity and high quality of gypsum powder. Therefore, the high level of gypsum powder production technology is required. In the process of gypsum powder production, drying and dewatering is the key link, which is also the most difficult one to control. In order to solve this problem, we develop a new type of drying and dewatering equipment---ebullience calciner, which is produced based on the exploring of the gypsum production filed. Following is the brief introduction of the gypsum production technology and ebullience calciner working principle.The Crusher will break the big-size gypsum ore into small 25mm pieces, and then the small pieces will be sent to the grinder, after grinding fine, the qualified raw gypsum powder will be sent to boiling furnace to calcine, and the unqualified part will be sent to grinder until its qualified. After calcining, the qualified gypsum powder will be sent to spiral conveyor through hoist. The spiral conveyor will send the calcined gypsum powder to silo for storage, and cool the powder during the process. The dust remover is on the top of silo, the unqualified part will be sent to grinder until its qualified. The stored gypsum will be sent to product storage through steel impeller feeder, spiral conveyor, hoist, and send the qualified gypsum powder to storage or workshop finally. The top pulse bag stype dust remover will collect dust from crusher, particle silo. When the dust and dust gas get into the dust remover through inlet, the big-size dust particle will fall because the increasing size and decreasing wind speed. The small dust particle will be filtered by filter bag. The filtered gas will be got rid of by outlet. Feel free to contact joyfang2009 at hotmail dot com.
