A Comparison between Tray Continuous Dryers and Rotary Kiln Dryers in Drying Nickel Ore Concentrate

The working principles and drying efficiencies of tray continuous dryers and rotary kiln dryers were presented. The advantages,and energy-saving and environmental-protection efficiencies of tray continuous dryers were verified through the comparison between the experimental data of tray continuous dryers and the practical production data of rotary kiln dryers.
