Drying unit

Fives has extensive experience in supplying flash drying technologies for customers worldwide. We select the system best suited to the constraints imposed by the physical properties of the material to be dried. We also consider the process context in terms of other equipment used (for example, ball mill grinding vs. FCB Horomill® grinding or separation). Our solutions are configured to obtain the best energy yields in reliable units. They also have a limited footprint, reduce the circuit pressure drop and offer efficient drying of any material, with minimal maintenance. Our tailor-made flash dryers are cost-efficient and suitable for a range of turndown ratios. Optimized equipment for every step of the drying process Our drying process schemes are designed according to the installation size and the physical characteristics of the material (such as grain size distribution, moisture, hydroscopy and stickiness). In most cases, the feed’s particle size distribution (PSD) will determine our flash dryer design. A Venturi-shape reactor or FCB Aerodecantor will be used, depending on the particle size. Then, a hammer mill or shredder can be placed in the flash duct at the upper level, to break up the material. The final-product grain size can be controlled by adding an FCB TSV™ Classifier at the top of the flash dryer. Rejects from the FCB TSV™ can be removed from the circuit or milled. The dry product can then be collected through a cyclone, a baghouse filter, or both.
