Hydrocyclone cut-size estimation using artificial neural networks
Van Loggenberg, S.; Van Schoor, G.; Uren, K.R.; Van der Merwe, A.F. (Elsevier, 2016)The hydrocyclone is widely used throughout the mineral processing industry when working with slurries. It is either used for classifying, desliming or dewatering. Hydrocyclones are inexpensive, application-efficient and ... -
A predictive model for a Wet-high-intensity-magnetic-separator (WHIMS) using artificial neural networks
Reichel, C.R.M.; Van der Merwe, A.F.; Cronje, J. (EARET, 2018)—Materials can be classified into three major categories based on the magnetic susceptibility thereof; the property governing the response of the material subjected to a magnetic field. Chromium has many uses in the ... -
Statistical modelling of an ammonium nitrate fluidised bed granulator for inference measurement
Kok, Rudolph L.; Van der Merwe, Abraham F.; Van Schoor, George; Uren, Kenny R. (Elsevier, 2019)Fluidised bed granulation is a widely used wet granulation technique. The operation of a fluidised bed granulator (FBG) as well as the quality of the product is strongly influenced by multiple process variables and ... -
Sulphur trioxide decomposition with supported platinum/palladium on rutile catalyst. 2. Performance of a laboratory fixed bed reactor
Stander, B.F.; Everson, R.C.; Neomagus, H.W.J.P.; Van der Merwe, A.F.; Tietz, M.R. (Elsevier, 2015)The construction, operation and experimental evaluation of a laboratory scale fixed bed reactor for the decomposition of sulphur trioxide with a supported platinum and palladium based catalyst, were undertaken. The heating ... -
Sulphur trioxide decomposition with supported platinum/palladium on rutile catalysts. 1. Reaction kinetics of catalyst pellets
Everson, R.C.; Stander, B.F.; Neomagus, H.W.J.P.; Van der Merwe, A.F.; Le Grange, L.; Tietz, M.R. (Elsevier, 2015)An investigation was undertaken to evaluate the intrinsic reactivity, stability and associated diffusional parameters of catalyst pellets consisting of platinum and palladium on rutile for the conversion of sulphur trioxide ...
