Giving compression and the shear force which are strong in the powder granule, being something which treats such as compounding, structure is simple, the central processing unit which can find optimum treatment condition simply is offered. Mixed vessel the Interpolation passing the vessel bottom of 20 of vertical die and mixed vessel, 20 locking in the multiple agitation feathers 40 which are provided in the revolving shaft 30 which, is provided and revolving shaft 30 and mixed vessel 20 it has the multiple collision boards 50 which are provided. When designating the diameter of mixed vessel 20 as d, agitation feather shortest distance of 40 and collision board 50 has made below 0.1d.粉粒体に強い圧縮力や剪断力を与えて複合化などの処理を行うものであって、構造が簡単であり、最適な処理条件を簡単に見つけることができる処理装置を提供する。竪型の混合槽20と、混合槽20の槽底を挿通して設けられる回転軸30と、回転軸30に設けられる複数の撹拌羽根40と、混合槽20に固定して設けられる複数の衝突板50を備える。混合槽20の直径をdとするとき、撹拌羽根40と衝突板50との最短距離が0.1d以下としている。
