Based on this consideration, the design of three-flow system is independent of the sizing and selection of domestic and foreign advanced equipment to meet the quality requirements of cardboard vermicelli and the smooth operation of high-speed paper machine. The design includes mapping serofluid balance calculation, equipment selection and calculation, workshop equipment layout, equipment levation, the whole process flow diagram and general layout of the rendering plant. By beating the system and process flow design, production paper machine systems to master the technology and process design of the preliminary master procedures and working methods. Keywords: Pulp and Papermaking, Liner board, Approach system;Beating system
