Abstract

PURPOSE:To prevent clogging by providing a coarse particle discharge port communicated with a classifying chamber to the casing side part of the classifier provided with various devices. CONSTITUTION:The raw material supplied from a raw material feed port 15 is imposed on a screen 11. While the raw material is turned upside down on said screen 11, all the particles come into contact with the screen 11. The particles past the screen fall onto a bottom plate 16 and are recovered as the fine particles transferred to a fine particle discharge port 17 by the effect of an oscillation generator 26. On the other hand, the large-grain particles which cannot pass the screen 11 are transferred to the coarse particle discharge port 18 and are thereafter recovered as the coarse particles. The clogging is thereby prevented and the long-period operation is enabled.
