摘要

PROBLEM TO BE SOLVED: To provide a dry type medium agitation pulverizer used in a batch process, high in treatment efficiency and capable of attaining a sharp particle size distribution.SOLUTION: A dry type medium agitation pulverizer 10 is equipped with an agitator 30 on a revolving shaft 31 inserted from one end wall 21 of a pulverization container 20 forming a cylindrical shape. The pulverization container 20 is formed with a supply port 50 and an exhaust port 60 for a processed product, and the exhaust port 60 is formed in the other end wall 22. The pulverization container 20 is made rotatable so that it can position the revolving shaft 31 horizontally and in a position turned by 30° or more from the horizontal position.SELECTED DRAWING: Figure 1
