Along with the occurrence of energy crisis, the prices of energy is higher and higher in recent years. In order to reduce the cost for energy, it is necessary to take some measures to change the operation conditions of coal slime dryer or choose sludge dryer with high thermal efficiency. In general, to maintain the appropriate temperature in medium or large-sized machines, the heat loss should be at about 5%. Similarly, the heat loss for coal slime dryer is no more than 10%. Thus, to well keep the heat in drying system, the thickness of insulation layer should be optimal.

The ventilating machine and draft fun should be generally used in series to avoid the leakage of drying system. For the fear of low heat efficiency due to the leak-out of drying medium or leak-in of outside air, the sludge dryer should be reasonably adjusted to work under zero pressure. Before the entry into coal slime dryer, raw materials should be primarily dehydrated by the ways of filtration, centrifugal separation and evaporation. Primary dehydration is the most effective way for increasing the solid content in raw materials and reducing the evaporation load of coal slime dryer.

To improve the drying efficiency of sludge dryer, users can improve the inlet air temperature and reduce the outlet exhaust temperature. Proper improvement for the inlet air temperature is useful to promote the heat efficiency. It is worth to being noticed that the inlet air temperature is limited by the allowable temperature of material.
