SN-Spheres are a series of separated products directly from fly ash in dry conditions at the fly ash disposal area. With the advanced technology of bulk conveying, more and more power plants have adopted the method of fly ash dry disposal. This makes separation of cenosphere impossible.However, the dry fly ash presented us a chance to separate many other different glass particles with comparatively lower cost than wet material.
