Abstract
PURPOSE: To obtain a granulated substance which is large in its strength and gas permeability, by specifying the weight ratio of grain of both a boundary grain diameter or below and its half of below, when granulating a sintering material by a pan pelletizer.
CONSTITUTION: When granulating a sintering material such as a mixed material, a new material, etc. by a pan pelletizer, grain size of the sintering material is adjusted as mentioned below. That is to say, weight of grain of a boundary grain diameter 0.5mm or below of the sintering material is set to 30W60% of the total wight. Also, weight of grain of 1/2 or below of a boundary grain diameter 0.5mm is adjusted so as to be 75% or above against weight of the boundary grain dameter 0.5mm or below. According to such a constitution, gas permeability of a granulated substance obtained in the outlet of a granulating machine is elevated rapidly, also strength of pseudo grain is increased, it is not disintegrated in the process of transportaion and charging, and gas permeability on the pallet is elevated.
