A process for preparing waste paper

摘要

In order to save energy and to economise on plant components, in the process for preparing relatively clean, pre-sorted waste paper the following preparation steps are carried out: a) Pulping in the breaker (1) to a stock consistency of more than 15%, b) Delivery from the breaker (1) with the pulp stock at the consistency level established therein, c) Sorting of the pulpy paper stock by conducting it past a metal-seeking device (5), d) Introduction into a dispersion appliance (4) with an operating range which lies within the pulp stock consistency established in the breaker (1), e) Dispersion of the pulp stock in the dispersion appliance (4), f) Ensuing thinning of the pulp stock, g) Further preparation of the pulp by fine sorting and fine cleansing for the purpose of supplying it to the paper or cardboard machine.
