What happens in crushing is that some of the material gets crushed down to the size you want but other pieces don't. The small stuff then often gets in the way of the crushing process as you are working, basically protecting the larger pieces from being crushed and creating more work.

After crushing, grinding, magnetic separation, flotation, and gravity separation, etc., iron is gradually selected from the natural iron ore. The beneficiation process should be as efficient and simple as possible, such as the development of energy-saving equipment, and the best possible results with the most suitable process.
