Description

dn er den relative densitet af væsken til vask eller separation, do er den relative densitet af den væske, der udledes ved af de faste materialer i suspensionen, g er tyngdeaccelerationen, 0 er diameteren af perfora-tionerne, og 1 er middelafstanden imellem perforationerne. Kj indstilles til en værdi på mindst 10 og fortrinsvis på mellem 20 og 300.dn is the relative density of the liquid for washing or separation, d0 is the relative density of the liquid discharged by the solids in the suspension, g is the acceleration of gravity, 0 is the diameter of the perforations, and 1 is the mean distance between the perforations. Kj is set to a value of at least 10 and preferably between 20 and 300.

Herved opnås resultater, der ligger meget tæt på de teoretisk opnåelige resultater.This results in results that are very close to the theoretically achievable results.
