A pulp and paper-making multiple-producing mill, producing 250000 tons of corrugated container board every year
Focus: technological design of wet section and press section

Abstract: The corrugated container board is one of the main paper product in Zhejiang province. Wet section and press section is the key parts to the quality of the corrugated container board. Through the technological design of wet section and press section, we can have a great understanding of the process and technology of production of corrugated container and get familiar with the procedure of technical design and operating methods. The article is about the primarily design of supplying pulp system and wet section technology of papermaking mill which producing quarter million tons of corrupted container board. The main contents of design include: (1) Feasibility analysis of building a mill；(2)Product mix and production process of all mill；(3)Product features of the workshop and the choice of technological flow and process condition；(4)Mass balance and equipment selection of the main equipments；(5)Consumption indicator of water, gas and electricity and size of personnel force；(6)Arrangement explanation of processing equipment in the mill；(7)General survey of design
