In-Plant Testing of Teetered Bed Separator in Omerler Washing Plant

Abstract

In this study, the performance of pilot scale teetered bed separator (TBS) was evaluated using the data obtained in Omerler coal washing plant in Kutahya region. One of the individual spiral feed was used as feed for TBS. Pressure set point and the amount of teetered water were used as operating variables. At steady state conditions, the samples were collected from feed, underflow and overflow. Then, the samples were sieved into size fractions and the ash contents were determined on size basis. The results showed that both cut density and Ep decreased with increasing particle size verifying earlier observations published in the literature. If clean coal is targeted, single stage separation suffers from high coal loss. However, it was found that significantly higher ash content was obtained with TBS comparing with the spiral tailings.
