PURPOSE:To provide a granulating method for sintering a raw material, by which a large quantity of fine powdery ore can be used as the sintering raw material and strong mini-pellets having the desired grain size can be manufactured. CONSTITUTION:The sintering raw material is kneaded to be compact and plastic and made to a flaky state and charged into an agitation trough type granulating machine. The agitation trough type granulating machine is provided with plural troughs 1 and the main body is constituted of a cylinder 3 fixed to a frame with a spring 2 so that the inclination theta is variable. Further, a bearing 4 is provided on the lower part of the main body and a shaft 6 provided with unbalanced weights 5 is provided on the bearing 4 and by rotating the unbalanced weights 5 with a motor 7, circular vibration is transmitted to the shaft 1. This is operated in the range of >10 deg. and <=25 deg. inclination theta of the trough 1. |
