| description | Hydrocyclones are devices worldwide used in mineral processing for desliming, classification, selective
classification, thickening and pre-concentration. A hydrocyclone is composed by one cylindrical and one conical section
joint together, without any moving parts and it is capable of perform granular material separation in pulp. The mineral
particles separation mechanism acting in a hydrocyclone is complex and its mathematical modelling is usually empirical.
The most used model for hydrocyclone corrected cut size is proposed by Plitt. Over the years many revisions and
corrections to Plitt´s model were proposed. The present paper shows a modification in the Plitt´s model constant,
obtained by exponential regression of simulated data for three different hydrocyclones geometry: Rietema, Bradley and
Krebs. To validate the proposed model literature data obtained from phosphate ore using fifteen different hydrocyclones
geometry are used. The proposed model shows a correlation equals to 88.2% between experimental and calculated
corrected cut size, while the correlation obtained using Plitt´s model is 11.5%. |
