Rotary dryers efficiency result in the amount of exhaust gas increases, thereby increasing the the precipitator burden and corrosion, its service life is shorter.We analysis the precipitator corrosion phenomenon fo rotary dryer form three aspect. We should care about he three aspects to maintain the rotary dryer.

Continuous rotary drum dryer is used for the following reasons: if the whole process is continuous, select the continuous method; for the same material, and the same amount, the use of continuous drying method can improve thermal efficiency of slag dryer; even the continuous drying time is short, the continuous method is beneficial; although it is suitable for large processing, but the drying time of materials is particularly long, intermittent drying machine is often used.

After we understander the the differences between continuous coal slime dryer and intermittent rotary dryer, we will choose exactly the type rotary dryer that suitable for own conditions.improper operation is also easy to corrosion and damage caused by the dust removal system, some manufacturers habitually precipitator in the wet state to shut down, after conclusion of the work, thus accelerating the corrosion of the dust removal system.

When the material’s supply, remove, equipment transportation and other operation are difficult, using intermittent drying equipment is better; because the structure of this kind of device is relatively simple, so its fault is less and its price is cheap; when the drying time is long, the drying process can also carry out other operations, so it can improve the operating density.the chicken manure dryer equipment air leakage and insulation tight enough (especially in winter), so that the cold air into the dust caused condensation, causing serious corrosion.
