  • Iron ore pellet having a specific shape and a method of making the same
    Patent number: 4129437
    Abstract: In the present invention, after a powdered iron ore has been subjected to granulation and firing into spherical pellets, a further crushing is applied while adjustment of the particle size of the crushed pellets is made so that the outer surface of the pellets is composed of spherically formed surfaces and crushed surfaces. By doing so, improvements are made in the angle of repose and in the reducing characteristic of iron ore pellets, and eventually an efficient and highly economical blast furnace operation is attained.
