Uniaxial compressive strength (UCS) is a key physical test relevant to iron ore crusher design and rock geomechanics for mining. Tests are typically performed on intact lengths of NQ, HQ, or PQ diamond drill core and record the maximum axial load sustained at the point of failure.
When the addition amount of iron ore was 30%, the crushing strength of QE3 dropped to 18.15%. The crushing strength of ferro- coke QE4 and QE5 were both 0.
When the ore passes through the coil, the magnetic field strength will be changed if the iron content is too high. The magnetic field strength change will be converted into a current value by an electromagnetic conversion device, which will be input into a detection instrument, and the instrument will indicate that it is currently in an "iron ...

1. Introduction. Due to the decreasing reserves of high-grade iron ore and secondary resources used for steelmaking, it has become an important research and …
The crushing strength of the 1 day normal cured pellets is in the range 12-35 kg/pellet. In general, the higher the moisture content in the green pellets, the higher is the 1 day strength. Crushing strength of I day normal cured pellets increases with increase in binder content and is maximum in pellets contain- ing 12% clinker.
The most expedient method of measuring the degree of particle coherency within an iron ore pellet is the crushing test. A specific test carried out as a measurement of value, such as the crushing strength of fired pellets, is only as good as the degree of reproducibility of the test. Results of Laboratory Pelletizing Tests
The factors influencing the crushing strength of a metallised iron pellet has been studied after hydrogen reduction at temperatures between 923 and 1273K using commercial acid iron ore pellets as the starting material. The results show that the strength is closely related to the degree of maximum swelling rather than to the degree of final swelling.

The RB 1000 Iron Ore Pellet Crushing Strength Determinator is an automated system for the determination of the crushing strength of fired iron ore pellets and reduced iron ore pellets, according to ISO 4700 Standard and ASTM E 382-83 Standard.
ABSTRACT The present study demonstrates the effect of the different morphological types on the cold crushing strength (CCS) of heat-treated iron ore pellets. Blends with different iron ore oxides morphologies were subjected to grinding, filtering and pot grate tests on industrial scale trials. Results of grinding tests showed the hematite-goethite …
The contributions of three operating parameters (moisture content, hydrated lime addition, magnetite concentrate substitution) to the crushing strength and Young's modulus of granules in each stage of iron ore sintering were studied by applying the Taguchi method. The results indicated that the strength properties of the iron ore granules were greatly affected by …
When the amount of iron ore was 30%, the crushing strength of ferro-coke dropped to 18.15%. Among the four binders, coal tar pitch could significantly enhance the cold crushing strength of ferro-coke through decreasing the porosity of ferro-coke and improving the bonding effect between carbon matrix particles. In the case of the 10% coal tar ...
