METHOD AND SYSTEM FOR PRODUCING PULP USING WASTE PAPER-RECYCLING APPARATUS, AND THE WASTE PAPER-RECYCLING APPARATUS

摘要

PPROBLEM TO BE SOLVED: To provide a pulp production technique achieving a utensil-sized waste paper-recycling apparatus installable not only in a large-scale business establishment but also in the indoor of a small-scale shop or ordinary household or the like. PSOLUTION: The pulp production technique is such that: in a pulp production process for producing waste paper pulp by beating waste paper, beating-acting surfaces 41a and 42a are placed oppositely each other at a small beating gap, and a grinder 40 equipped with a pair of relatively rotating beating discs 41 and 42 is installed to form a waste pulp circulatory path 39; waste pulp subjected to beating by the grinder 40 is further subjected to beating step while circulating through the path 39; wherein the beating gap G between the beating-acting surfaces 41a and 42a is gradually made narrower gradually from the initial period of time toward the terminal period of time; thereby, a smooth and high-efficiency beating of the waste paper is achieved consistently in a limited narrow workplace space.
