Spray drying is known for its dry powder particles with good flowability, excellent particle surface characteristics and a reasonable particle size distribution. However, using conventional techniques to dry corrosive and abrasive materials requires the use of high mechanical shear forces during the spray process, which can lead to increased maintenance costs.
The specially designed pulsed combustion spray dryer overcomes this deficiency. The dry powder performance obtained with this dryer is comparable to that of a conventional system but is much less affected by corrosion and wear than before. This is due to the fact that pulse dryers use automated aerodynamic forces rather than mechanical shear forces. Thus, with this pulsed-fired dryer, manufacturers can not only reduce maintenance costs when drying abrasive materials, but also have a large specific surface area, a high activity and a narrow particle distribution range. The pulsed-combustion spray-drying system is not new technology, but for many existing drying systems, the latest development of this technology makes it an excellent drying method that is very suitable for these systems, excellent particle surface properties, consistent particle size And the narrow particle size distribution is critical to the final product performance.
Another advantage of using this technology is that the spray pressure is low and the slurry transfer piping system is open. In this way, the thick solid particles can be dried without dilution, so that the powder production efficiency can be improved and the process cost can be greatly reduced.
