The concept of using a spray dryer to convert fluids into dry powders is a simple one and has been utilized for many decades. The straightforward technique uses a heater with gas flowing through it (usually air) to dry the fluid. The thermal energy of the hot gas is consumed in evaporation so there is no heat damage to the product being treated.

There are two ways to approach the production of nanopowders: large-to-small or small-to-large. When working with large materials like metals or minerals, the powders are generated by attrition. The techniques here are primarily mechanical, using dry milling equipment like jet mills or roll mills. If you work with molecules such as sodium, the ...

For laser powder bed fusion, the typical range is 15-45 microns. Very fine powders below 10 microns can cause handling issues. Size range of 25-35 microns is commonly used. Binder jetting uses finer powders in the 5-25 micron range to improve sintering. Layer thickness also dictates minimum particle size.

This is the operational principle behind powder coating. Powder coating uses an electrostatic charge to attract powdered bits of plastic to a conductive metal part. Once the part is covered, it's heated to fuse the powdered particles together and onto the surface of the part. The result is a smooth, thin, non-porous plastic coating that is ...
