Feed is again back to the supply feeder 11 is also recycled.

이와같이 된 본 발명은 수분이 다량 함유된 고함수율의 피분쇄물을 건조와 분쇄를 동시에 1치 조분쇄 및 건조영역을 통하여 예비 전처리하고 , 2차분쇄영역에서 초고속의 유체를 사용하여 제트기류에 의한 2차 미분쇄함으로서 피분쇄물의 입자분포차이가 크고 입자간의 불규칙적인 에너지 및 입도분포를 가진 피분쇄물도 균일한 입도분포를 가지는 초극미분의 좁은 입자의 피분쇄물을 얻을수 있고, 2중 분쇄영역에 의한 분쇄로서 에너지 절약 및 단위시간당 분쇄의 양이 배이상 증가될수 있는 효과가 있다.The present invention thus obtained is preliminary pre-treatment of the high water content pulverized material containing a large amount of water at the same time through the first-value coarse crushing and drying zone, and by using a jet stream using ultra-high speed fluid in the secondary crushing zone By the second pulverization, the pulverized product having a large particle distribution difference of the pulverized material and having irregular energy and particle size distribution among the particles can be obtained with a finely divided fine pulverized powder having a uniform particle size distribution. As a result of the pulverization, the energy saving and the amount of pulverization per unit time can be more than doubled.
