Waste Paper Pulp Machine Disc Thickener

The waste paper pulp machine disc thickener is a key piece of equipment in the pulp and paper industry applied for pulp thickening and fiber recovery. It is widely applied to the dewatering and thickening of various pulp types, such as chemi-mechanical pulp and recycled pulp, while also playing a vital role in paper machine white water systems by facilitating fiber recovery and the fractional reuse of filtrate.
Disc Thickener Function
Pulp Thickening and Washing: applied for thickening pulp after bleaching or screening/cleaning stages; it can replace multiple drum thickeners and offers advantages such as minimal fiber loss, low energy consumption, and a compact footprint. In waste paper pulping, it is commonly used for thickening pulp following flotation washing.
White Water Recovery and Fiber Reuse: Processes white water from the paper machine’s forming and press sections to recover fines; the filtrate is graded by clarity for reuse.
