Abstract
This present invention intends to provide a continuous type vertical planetary ball mill performing with high efficiency. In this ball mill, a mill pot is provided with an entrance and an exit which are vertically open. The entrance communicates with a charging port of a charging case which rotates together with a revolving rotary body, and the exit communicates with a discharging case fixed to a bed so as to allow only fine particles to pass through. Compressed air is supplied to bearings interposed between an airtight chamber and a fixed shaft, between the airtight chamber and a rotary shaft, and between the airtight chamber and a mill casing. As a result, this continuous type vertical planetary ball mill is stable in construction as compared with the conventional vertical type of ball mill and enables a high speed operation. Crushing performance and material quality reforming performance are improved. As a wide range of choice in production means is assured as compared with the knwon batch system, this ball mill contributes to development and production of new functional materials.
