figure of rotary dryer

Figure 1. The rotary kiln is most typically a carbon steel cylinder lined internally with refractory. In a direct-fired kiln, the hot gases of combustion are in contact only with the refractory lining and product, thereby protecting the steel structure of the vessel from high temperature stresses

    The directly heated rotary dryer operates on the principle of lifting and showering the product through a hot gas stream moving. The efficiency of the dryer is largely dependant on the differential between the inlet and exhaust gas temperatures, although the heat transfer rate is also influenced by the relationship between the design of flights

    Each type of rotary dryers has the same working principle on the gravity and heat exchange. A brief introduction to the rotary dryer processing principle is given taking the counter-current rotary dryer as an example. From figure-1 you can see that in the counter-current cylinder, the material moves in the opposite direction to the hot air
