co current and counter current flow rotary dryer

A rotary dryer using counter-current flow is to be used to dry 12000 kg/hr of wet salt containing 5% water (wet basis) to 0.1% water (wet basis). Heated air at 147°C with a WBT of 50°C is available. The specific heat of the salt is 0.21 kcal/kg °C. The outlet temperatures of air and salt are 72°C and 93°C respectively We are a professional mining machinery manufacturer, the main equipment including: jaw crusher, cone crusher and other sandstone equipment;Ball mill, flotation machine, concentrator and other beneficiation equipment; Powder Grinding Plant, rotary dryer, you can click the button to consult us.
