As its name implies, the coal slime dryer with another name of sludge dryer is mainly used to try materials like coal slime and sludge, etc. With features of high working efficiency and reliable operation, Dingli sludge dryer is well-received among the world markets. The following content mainly discusses about the ways to reduce the cost for users of coal slime dryer.

Generally speaking, the energy consumption of coal slime dryer is mainly for evaporating water content and bring away exhaust. While the latter nearly accounts for 15%-40% and even 60%. Two demands should be met if users want to lower the outlet exhaust temperature. One is the water content in finished products and the other is that the exhaust temperature should be higher about 20-60℃ than dew point when entering into the cyclone separator or cloth bag filter.

Since the waste heat in exhaust air can improve the heat efficiency of sludge dryer. While along with the recycling use of exhaust air, the humidity in hot air will increase a lot and the drying efficiency of coal slime dryer will decrease. Therefore, Exhaust Gas Recycling has an optimal range varying from 20% to 30%. Except for the above methods to recycle heat from exhaust air, users can indirectly take some heat exchangers to recycle heat from the exhaust air. The commonly used heat exchangers are enthalpy exchanger, plate heat exchanger, heat pipe and pump, etc.
