Precursor Feeder
Precursor feeders are among the most important pieces of equipment for a number of industrial applications involving powder conveyance, such as thermal spraying and advanced materials processing. As different powders have very distinct sizes, shapes, and other physical and mechanical properties, it is nearly impossible to convey each type in a continuous manner using a single feeder model. For this reason, different equipment is needed for each type of powder. For instance, powder feed rates for thermal spraying or powder spheroidization can be relatively large, while the feed rates for nanometric powder synthesis are low to ensure the full evaporation of the powders injected into the heat source. Tekna has developed a unique expertise in precursor manipulation. Our general design rule is to ensure that the powders will feed continuously and uniformly at the desired rates. Particular attention has been given to minimizing pulsations and agglomerations. On-line monitoring and control of the powder feeding is also taken into consideration to facilitate the operations.
We offer a complete a line of powder feeders adapted to a wide range of powder properties and flow rates as well as liquid and vapor feeders.
