And to II spread the raw material, the supplementary material, the coating which in the cloth white paperboard production process used has carried on the choice proof, explained the selection reason, considered in particular the cost question, massively used the scrap paper to carry on the production. The present paper second part has carried on the proof to the production process, and has drawn up the production process block diagram, has carried on the starch balance computation, the equipment shaping computation and the shaping to the production process, draw sup 100,000 t/a to spread the cloth white paperboard the production process diagram. Keywords:coated white paperboard, waste paper, production flow
