Abstract
A powder recycling system includes a powder feeder, a remaining powder collector, a bridge breaker, a block powder filter, a cyclone separator, a particulate filter cleaner, an air pressure generation device and an electrostatic precipitator. The powder feeder provides a construction powder to a construction platform. The remaining powder collector for collects the remaining powder. The cyclone separator is used to separate the large-size powdery particles and the small-size powdery particles of the remaining powder from each other through a rotating gaseous stream. The large-size powdery particles fall down to the powder feeder due to gravity, and the small-size powdery particles of the remaining powder is removed from the rotating gaseous stream and transmitted to the particulate filter cleaner. After the small-size powdery particles of the remaining powder are filtered by the particulate filter cleaner, the suspended small-size powdery particles are transmitted to the electrostatic precipitator.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
