Reject Handling

The dewatering of rejects to highest dry contents represents a fundamental process for the paper industry from an economic as well as ecological point of view. Especially in waste paper preparation plants but also in mechanical and chemical pulp mills. With maximum dry contents, we minimize volume and weight. Hence we meet the customer demands such as the reduction of transport and landfill charges. Furthermore, high calorific value to achieve constant and ecological incineration without additional heating.

Most modern paper mills are among our customers for complete systems that produce RDF from their rejects. Generally, the treatment of rejects from waste paper processing plants is integrated into the paper mill. The same processes may, however, be used by specialized waste disposal companies. In short, the separation process of valuable constituents such as metals and impurities is of importance.

Advantages:

  • Adjustment to customer requirements
  • Maximum dryness = high calorific value = maximum economic performance
  • High capacity of up to 250 BDTPD
  • Defined particle size (where required)
  • A defined level of Fe and non-ferrous contamination
  • Storage and transportation of RDF

Rejects from chemical and mechanical pulp mills

Bellmer thickens rejects from chemical and mechanical pulp production, such as knots, branches, fibre bunches and chips are thickened by our thickener AKSE®. In a downstream stage, the rejects are further dewatered with our AKUPRESS AS/AX screw press in order to reach even higher dry contents. Both the thickener and the screw press are always tailored to the individual operating conditions and adapted to the materials used. Thus, they comply with the current regulations regarding occupational safety and emission protection. We always include the requirements and wishes of our customers in our project planning.
