An operational model for a spiral classifier
A semi-empirical mathematical model for a spiral classifier is proposed in this paper. The model is based on the observations of the movement of particles within the trough of a spiral and makes use of several hypotheses that still need to be validated with dedicated experiments. The objective of the model development was to allow the ...
Full article: An Instrument for the Classification of Aerosols …
This paper reports theoretical models of a new instrument, called the aerodynamic aerosol classifier (AAC), which produces a monodisperse aerosol classified by particle relaxation time. The AAC does not rely on particle charging so it produces a true monodisperse aerosol without classifying multiply-charged particles like the DMA, …
Spiral classifier or hydrocyclone
The preferential classification benefit of cyclones is further illustrated in Table 2 which compares the metallurgical results of cyclones versus spiral classifiers in a copper grinding circuit. The cyclone produced an overflow product containing more copper in the finer size ranges where it will be subject to higher recovery in flotation.
A Guide to the Proper Application of Classifiers
A Guide to the Proper Application of Classifiers S EPARATING a mixture of particle sizes of mate- rial suspended in a liquid medium is by no means an exact science. Selecting machines for individual classifying operations is even more difficult.
Types of Classifiers in Mineral Processing
Spiral Classifier In mineral processing, the Akins AKA spiral or screw Classifier has been successfully used for so many years that most mill operators are familiar with its principle and operation. This classifier embodies the simplest design, smallest number of wearing parts, and an absence of surge in the overflow. It separates …
Enhanced gravity closed spiral classifier: Experimental …
Traditional gravity classifiers that leverage differential settling velocities in the gravitational field are bulky and ineffective for particles less than 150 μ m.In this study, a newly introduced compact enhanced gravity Closed Spiral Classifier (CSC) is tested experimentally for the classification of slurries containing silica or iron ore fines.
