How to improve the drying efficiency of sand dryer

1. Drum design: adopt three-layer return design: gradually reduce the water content of sludge and improve drying efficiency.

2. Hot air distribution: adjustable wind speed and temperature, according to the characteristics and water content of sludge, flexibly adjust the wind speed and temperature of hot air to optimize the drying process.

3. Stirring and turning: through the rotation of the drum and the design of internal blades, the sludge is constantly turned and stirred in the drum, increasing its heating surface area and accelerating the evaporation rate of water.

4. Exhaust and dehumidification: timely remove the water vapor generated in the drum to avoid moisture saturation, thereby improving the drying efficiency. Add dehumidification equipment at the air outlet to reduce the moisture content of wet air and improve the overall drying efficiency.

5. Feed uniformity: ensure that the speed and amount of sludge entering the drum are uniform to avoid uneven drying and inefficiency caused by uneven feeding.
