ABSTRACT:
Waste paper is fed into a horizontal drum and therein treated with suitable liquids to form pulp. A magnetic device is disposed adjacent one side of the drum to produce a magnetic field along one arcuate section and extending from the upper portion toward the bottom thereof. Magnetic particles mixed with the paper are carried by said arcuate section of the drum by virtue of the influence of the magnetic field until they reach the top where they leave the field and then fall downwardly into an inclined trough from which they gravitate to the exterior of the drum. Pulp is concurrently discharged from the drum.
