Abstract:
     An annular channel structure for grinder comprises vertically arranged inner and outer channel walls to constitute a separated annular channel, which has an air inlet and an air outlet to vertically pass airflow into grinding area. The annular channel is separated by a number of blades with tip end at inlet and an acute angle at its outlet relative to horizontal plane, so reducing the pressure drop of airflow into grinding area. A guide plate lower than inlet of channel can reduce air disturbance to make airflow enter channel smoothly.
