PULP & PAPER

Reactive and complex

Despite increasing digitalization, demand for paper and pulp products continues to increase, while the market is shifting from print paper qualities toward packaging paper and cardboard.

The wide range of paper products requires a variety of mechanical and chemical production processes that, depending on their form and variant, produce different pulp qualities. Stirring and mixing are essential unit processes in all types of paper and pulp production. Mixing tasks range from liquid/liquid and gas/solid/liquid mixtures to complex liquids and chemically reactive components.

Improving and optimizing mixing processes in the paper and pulp industry can improve the end product, for example through increased strength or improved luster, and can also result in significant energy or chemical savings. These process optimizations require precise analysis of process conditions, a clear definition of the objective, and an understanding of both the process and fluid mechanics. Geppert offers a range of proven agitators for applications across the paper and pulp industry to support these improvements and savings.

Fields of application

Dilution and make-up of bleaching solutions, melting of saline solutions, oxidation of alkalis, chemical recovery, preparation of paints and coatings, polysulfite production, paper pulp suspension.

Materials

Depending on the application, we use stainless steels (316Ti grade or higher), either bare or, in some cases, with abrasion-resistant coatings.
