The silicon powder produced by the roller mill may be used as feedstock for the silicon-lined jet mill or it may be used directly as the feedstock for the silicon-lined plasma gun. The jet mill allows powder size to be controllably reduced to a size of between 1 to 5 microns.

And those 800 hours only pertain to the time when the silicon powder reservoir is being used. If super matte or highly reflective surface finishing amounted to 20 percent of the total time machining, then you would have achieved 4,000 hours of machine use before maintenance would be required on the silicon powder reservoir.
