Patent ID: 7347105

Claim:
A method for the analysis of properties of a test specimen of reducible material that contains iron of the type raw pellet or pellet during the production of raw pellets or pellets for the optimization of the pelletization process and the subsequent extraction of iron by the use of an arrangement that demonstrates a first device and a second device spaced a distance from each other that can be displaced relative to each other by a force applied to at least one of the devices, said first and second devices including contact surfaces facing each other, which method comprises: a) arranging a test specimen between the contact surfaces; b) continuously reducing the distance between the contact surfaces; c) measuring the diameter of the test specimen when the test specimen makes contact with the contact surfaces; d) further displacing the contact surfaces in a direction towards each other during compression of the test specimen until the test specimen disintegrates; e) continuously recording and storing (i) the force that is applied to the test specimen and (ii) time; f) recording the maximum forces at all points of disintegration of the test specimen; g) presenting the measured values collected in real time; h) increasing the distance between the contact surfaces; and i) removing the test specimen or remnants thereof.
