Precursor Feeder

Precursor feeders are among the most important pieces of equipment in 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, the powder feed rates for the processes of thermal spraying or powder treatment can be relatively large, while the feed rates for nanometric powder synthesis are small, since it needs to be carefully controlled in order to ensure the full evaporation of the powders injected into the heat source. Tekna has developed a unique expertise in precursor feeder. The general design rule is to make sure that the powders can be fed continuously and uniformly at the desired feed 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 feeder adapted to a wide range of powder properties and flow rates as well as liquid feeder and vapor feeders.
 

Vibration Powder Feeder

1-10 μm powder with low flow
0.1-1 kg/h feed rate
Powder with low agglomeration property

Disk Powder Feeder

10-200 μm powder with relatively good flow
 0.5-10kg/h feed rate
 No pulsation

Nanopowder Powder Feeder


0.01-5 μm powder with very poor flow
 0.1-2 kg/h feed rate
Performs well also with powder with high agglomeration property
 

Suspension Feeder

Liquid feeder with low or high viscosity
Low pulsation

Vapor Feeder

Constant vapor flow
