  • SYSTEMS AND METHODS FOR REDUCING DUST IN GRANULAR MATERIAL
    Publication number: 20140262981
    Abstract: A method of removing dust from granular polysilicon includes introducing a stream of granular polysilicon, dispersing the longitudinal stream of granular polysilicon by redirecting the stream into a radially outward flow having a circular pattern, and introducing a counter flow of gas in an opposite direction to that of the longitudinal stream of granular polysilicon to contact the radially outward flow to separate the dust from the granular polysilicon.
    Type: Application
    Filed: March 13, 2013
    Publication date: September 18, 2014
    Inventors: Seok-Min Yun, Seong-Su Park, Se-Myung Kim, Won-Jin Choi, Woo-Jin Yoon
