Title: Iron ore pellet having a specific shape and method of making same and also method of operating a blast furnace
Inventor: TAGUCHI KAZUMASA

Abstract: ABSTRACT OF THE INVENTION This invention relates to an iron ore pellet having specially excellent properties as the raw material of iron in the production of pig iron and to a method of making the same and also to a method of operating a blast furnace.            Conventional iron ore pellets, due to their spherical shape, are liable to ununiformalize the layer thickness distri-bution of the materials charged in furnace resulting in reduction in operational efficiency of blast furnace.            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 a particle size of crushed pellet is made so that the outer surface of the pellets is composed of spherical 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.

Abstract: A harvesting apparatus has at least one pair of vibrating shaker head assemblies each with an input and an output member mounted for rotation.  A prime mover is coupled to the input member.  Rotary motion applied to each input member is converted into a torsional vibration superimposed on the output member, the output members being mounted so as to enable a rotary motion to be superimposed thereon and coupled together so that they have the same rotary motion.  As a result, the vibrational movement of one shaker head assembly is balanced with the vibrational movement of the other shaker head assembly.

Abstract: ABSTRACT            A vibrating feeder for feeding disc-like objects such as coins to a subsequent work station such as a coin sorter has a unitary box-like structure provided with a particularly contoured bottom.  The bottom defines a main flow path and an auxiliary flow path leading to the main flow path which in turn terminates in an exit for the coins.  The auxiliary flow path has longitudinally inclined fins for guiding coins to the main flow path while somewhat retarding the flow rate to avoid jamming of coins and to avoid an excessive flow rate.          Each flow path also includes one or more troughs contoured so that a coin will not lie flat thereon.  The feeder is inexpensive to produce, is simple in execution and operation and provides a controlled flow rate for coins or other objects to the subsequent work station.
