Investigation of using table type air separators for coal cleaning

In the present study, the application of table type air separators was investigated on three lignite samples and a hard coal sample collected from several regions in Turkey. The Yenikoy lignite sample was used to determine optimum test conditions. These test conditions were used to study Soma, Corum lignite, and Zonguldak hard coal samples with reference to feed rate, riffle height, table frequency, and table slope. Results were analyzed to determine calorific values and ash contents of clean coal and tailing samples. It is concluded from the study that the table-type air separator can be used for the Turkish coal with high-separation efficiency.
