Ring Dryers

Ring Dryers The ring diyer is a development of flash, or pneumatic-conveyor, diying technology, designed to increase the versatility of application of this technology and overcome many of its limitations. 

Three configurations of the ring dryer have been developed to offer flexibility in design and optimal performance ... 

P-type manifold—veiiical configuration. The P ring dryer (see Fig. 12-100) incorporates a single-stage classifier and was developed specifically for use with heat-sensitive materials. The undried material is reintroduced into a cool part of the dryer in which it recirculates until it is dry enough to leave the circuit.

Figure 9.12(c) shows that material circulates through the ring-shaped path and the product is withdrawn through the cyclone and bag filter. Performance data for a typical ring dryer are found in Table 9.13(c).
