FL Krebs CycloWash

The injection liquid serves as the displacement agent of fine particles entrained in the underflow pulp. In this secondary classifiion within the hydrocyclone, displaced fines rise within the center of the hydrocyclone joining the hydrocyclone overflow pulp. The coarse solids are thickened and discharged through the apex 

CFD simulation of an industrial hydrocyclone with Eulerian–Eulerian

SWECO Appliions, Pulp and Paper

SWECO specializes in filters, separators and centrifuges for pulp and paper appliions. The hydrated clay goes to SWECO Hydrocyclones to remove sand particles. The slurry is then screened on SWECO EM3 Rectangular Separators and sent via pipeline to the next stage. The slurry goes through sand grinders to get 

Hydrocyclone Wikipedia

The characteristics of the feed stream include size distribution of solids in the feed stream, pulp density (percent solids in the slurry), pulp viscosity and the inlet pressure for solid/liquid separation. In liquid/liquid feed streams, for example in oily water, the main feed characteristics are based on oil droplet size and distribution, 

Evaluation of two hydrocyclone designs for pulp DiVA portal

The process conditions and fractionation efficiency of two hydrocyclone designs, a novel and a conventional conical design, were evaluated. The novel design comprised a modified inlet section, where the pulp suspension had to pass a narrow ringshaped opening, and a very compact fractionation zone. The influence of

Applicability of fractionation of softwood and hardwood kraft pulp

Softwood and birch kraft pulp were fractionated using hydrocyclones and pressure screens, and eucalyptus kraft pulp using hydrocyclones. Softwood and birch kraft pulp were fractionated both as unbleached and bleached. In Chapters 6.1.1, 6.1.2 and 6.1.3, the fibre and pulp properties after the fractionation are presented.
