Recommended temperature for rotary drier is

What temperatures do rotary dryers typically operate at? Rotary drum dryers typically operate at temperatures between 200 F and 2200 F (93 to 1200 C). Which dryer type is best for my application – rotary drum dryer or fluid bed dryer?

  • Optimal Temperature Range for Compressed Air

    Optimal Temperature Range for Compressed Air

    Feb 15, 2018 This means that if the ambient temperature is 85 F, the incoming air from the compressor to the dryer will be 100 F at full load. This is why we say 85 F is the ideal maximum temperature. If keeping temperatures below 85 F is not realistic, you may need to install a larger dryer to compensate for high temperatures

    How Choose Vacuum Dryer - Chemical Processing

    A vacuum dryer's upper temperature limit (typically about 600 F) is lower than that of a direct-heat dryer. The rate at which material temperature can be raised in a vacuum dryer is also limited. This is because the indirect-heat vacuum dryer is limited by the surface area available for heat transfer, unlike a direct-heat dryer
