A deinking mill serves as a step in the recycling paper process. This type of mill detaches the ink from the paper fibers, along with any other excess materials which are also removed from the remaining paper. In the deinking mill, after all of the unwanted coatings of paper are stripped, the refurbished paper is sent to the paper machine.
Volume 2, Number 1 Apr 1989. Alkaline PaperMaking Conversion Rate Accelerates by Ron Westwood Market Development Manager, Pfizer Inc. The rate at which paper mills are converting from acid to alkaline papermaking has accelerated in recent years.
The deinking process for the effective removal of ink from waste paper, has evolved over years. It is typically carried out by converting the waste paper to a pulp and then separating ink particles and other impurities from the pulp fiber.
