An Introduction to Centrifugal Cleaners provides a practical technical overview of centrifugal, vortex, hydrocyclone, and cyclone cleaners used in pulp and paper stock preparation. The paper explains operating principles based on centrifugal, drag, and buoyancy forces; performance factors such as pressure drop, flow rate, consistency, reject rate, particle size, and removal efficiency; and the design considerations that influence cleaner operation.
Coverage includes high-density, fine or forward, lightweight or reverse, through-flow, rotating-body, and dual cleaners. The document also discusses contaminant separation, safety precautions, cleaner materials and configurations, plugging and process-control considerations, and the placement of cleaning equipment in recycled fiber systems. It includes equations, performance figures, cleaner diagrams, contaminant comparisons, and a recycled fiber system flowsheet.
Application Scope: Suitable for pulp and paper engineers, stock preparation specialists, mill operators, maintenance personnel, technical students, and professionals evaluating or operating centrifugal cleaning systems.
