An Experimental Study To Identify The Design Variants In Design And Developing A Single Column Classifier

Classifiers are used in minerals processing for extracting the valuable minerals. Effectiveness of classifier depends on how effectively the classification of particles is been done based on the cut size. The main factor is teeter bed formation which has high impact on classification of particles depending on their size and density. Heavy particles move to underflow and the lighter particles move towards the overflow. The separation of lighter and heavy particle takes place at teeter bed. In this study, teeter bed is the primary focus area to understand the cut size particle behavior and enhance the effectiveness of the teeter bed in classification process. Experimental work is carried out using single column cylindrical classifier built in transparent material to study the particle behavior in teeter bed. Known quantity of sand slurry with different particle sizes is prepared and the classification results are tabulated and analyzed. From the analysis it is clear that stability of teeter bed is a key factor in achieving high efficiency in classification process. The various factors hampering the stability of teeter bed are induced due to agitation leading to variation of slurry concentration per cycle during the process and slurry pumping rate and pulsation in pumping.
