Iron Ore Processing,Crushing,Grinding Plant Machine

Iron ore is the key raw material for steel production enterprises. Generally, iron ore with a grade of less than 50% needs to be processed before smelting and utilization. After crushing, grinding, magnetic separation, flotation, and gravity separation, etc., iron is gradually selected from the natural iron ore.

The Work Index In Blasting U.S. Rock Mechanics

The 80% passing size P of the broken rock must be measured by size analysis or must be estimated to obtain the blasting work index. Two blasting tests (Bond, 1954) on Taconite iron ore in Minnesota five years ago gave work index values of 14.5 and 13.5, or an average of 14.0, which compares with 14.7 recently obtained in crushing this ore in

Bond Work Index an overview ScienceDirect Topics

The Bond work index is not solely a material constant but is influenced by the grinding conditions. For example, the finer the grind size desired, the higher is the kWh/t required to grind to that size. Magdalinovic [38] measured the Bond work index of three ore types using different test screen sizes. He produced a correlation between the mass of test screen undersize per revolution, G, and
