The manufacturing method and manufacturing apparatus of a paper material which used the waste plaster board separating paper as the raw material

SUBJECT of the Invention While making adhering plaster|gypsum amount into the minimum thru|or zero， without baking a waste plaster board， even if it remain|survives， the manufacturing method of the paper material which can suppress isolation|separation and scattering is provided. PROBLEM to be solved The manufacturing method of the paper material which used as the raw material the paper piece isolate|separated from the waste plaster board is with the crushing process 12 which crushes the waste plaster board 11 to a defined shape thru|or a size， The paper piece collection process 13 which separates/recovers a paper piece from a crushed material， The underwater stirring and the crushing process 14 which produces|generates the pulp liquid which eluted the soluble constituent etc. while throwing in the isolate|separated paper piece in water， kneading|massaging it， understanding it and disperse|distributing and suspending a plant tissue in water， The pulp collection process 15 which isolate|separates water， such as a plaster|gypsum， a free pulp， a soluble constituent， etc. which are contained in pulp liquid， and isolate|separates a pulp， The paper material formation process 16 which shape|molds a pulp to predetermined shape， The drying process 17 which dries the shape|molded paper material at predetermined|prescribed temperature is included.
