The graduation design is use carbonization method to product barium carbonate, the advantages of the method is to ine carbide, stable product quality, production cost is low. According to the production requirements and access to information, carries on the carbonization method barium carbonate production process design and related equipment design and selection. Use AutoCAD drawing software draw the process flow diagram, equipment layout, which makes the design results can basic to satisfy the production requirements.
