How do Tarmac’s engineers determine when to use Parallel Flow (Co-Currnet) or Counter Flow (Counter-Current) thermalrotary dryerdesign? The answer comes in typical rules for thedryertype choice. These rules can be modified due to specific drying needs. Simply stated, thermalrotary dryersare rotating cylinders that continuously bring wet solids into the […]
Get PriceDisadvantages of theCo-Current Rotary DryerHigher Exhaust Gas Temperatures The primary disadvantage of theco-currentdesign is that it is slightly less thermally efficient, because the exhaust gas can never be cooler than the temperature of the solids, requiring more energy to be spent on keeping theexhausttemperature up.
