ABSTRACT:
An agitating pulverizer which agitates an object and a binder charged into a tank and repeatedly granulates and pulverizes the object, thereby forming particulate matter with a desired particle size. The agitating pulverizer comprises a tank for allowing the object and the binder to be charged thereinto. A low-speed rotating member and a high-speed rotating member are provided at the central bottom portion of the tank and arranged to be rotatable in the directions opposite to each other. A lower agitating member is placed adjacent to the bottom of the tank and interconnected to the low-speed rotating member so as to push the object and the binder upward and also to draw them toward the center of the tank. An upper agitating member is interconnected to the high-speed rotating member and placed farther upward of the lower agitating member so as to push the object and the binder downward and upward, thereby applying shearing force and centrifugal force to the object. The object charged into the tank, together with the binder, is drawn toward the center of the tank while being pushed upward by the lower agitating member. The object is further agitated while being subjected to shearing force and centrifugal force by the upper agitating member, and is repeatedly granulated and pulverized, thereby forming into particulate matter with a suitable particle size.
