Since long, LIST KneaderReactors are in successful operation in many industrial recycling processes where valuable products are recovered and the actual wastes are treated such that they are ready for disposal or incineration. Most of these thermal processes have in common, that during the treatment, the product undergoes various states from liquid via pasty to dry. The unique ability of the robust LIST KneaderReactors to handle the various product states and phase changes in one single batch or continuous machine enables our customers to significantly lower their investment and operating costs and boost the profitability of their industrial production.

The recycling of a blend of diverse types of plastic is a growing market for the recycling industry. LIST has developed processes to devolatilize the recycled polymer to take the solvent content to values below the permissible limits.

Example

  • Bio sludge
  • Oil sludge
  • Paint sludge
  • Sewage sludge
  • Solvent recovery
  • Radioactive waste
  • Polymer waste

LIST technology for the Drying of Paint Sludges with Solvent Recovery

The increase in the amounts of paint and lacquer sludges from industrial processes combined with more stringent legislation, reduction in available land-fills, escalating costs, and the increasing pressure for residues to be processed at the point of origin has created a tremendous incentive for the development of new and economic concepts and techniques for their minimisation.

Das Beste herausholen

Bei der Aufbereitung von Industrierückständen, Schlämmen und Sonderabfällen müssen nicht nur gesetzliche Vorschriften beachtet werden. Sinnvoll ist es, die Aufbereitung am Entstehungsort vorzunehmen; darüber hinaus sollte eine maximale Rückgewinnung an Wertstoffen sowie ein Minimum an unvermeidbaren Reststoffen gewährleistet sein.

Polutex – Drying of industrial sludges and distillation residues

This paper elaborates on the constraints of the drying process of industrial sludges and distillation residues, such as, closed design and product containment, processing of sticky, crusting, or fouling intermediate phases, versatility, low energy demand, and single step drying. It then presents the mechanical, thermal and processing features as well as the operating principles of specialised single-shaft, DISCOTHERM B CONTI/BATCH, and twin-shaft, ORP (Opposite-Rotating Processor) CONTI, kneadersdryers.
