Jaw breaking cone breaking combined crushing of iron ore, iron ore crushing

Jaw breaking cone breaking combined crushing of iron ore is a process used in iron ore beneficiation to reduce the size of run-of-mine (ROM) iron ore. This process involves using both jaw crushers and cone crushers to achieve a graded ore product with a specific size range. The ore is typically crushed to a size of not less than 1500 microns (or 1.5 mm).

In this process, the iron ore is first fed into a jaw crusher, where it is broken down into smaller pieces. The jaw crusher typically operates by applying pressure to the ore between a fixed jaw plate and a movable jaw plate. The ore is then transferred to a cone crusher, where it undergoes further crushing.

The cone crusher works by using a rotating cone that applies pressure to the ore against a fixed cone. The ore is forced between the cones, and the rotating cone crushes the ore against the fixed cone, reducing the size of the particles. The graded ore product is then separated according to size, and the desired size fraction is extracted for further processing.

This combined crushing process is used to achieve a uniform size distribution of the iron ore, which is essential for efficient beneficiation and downstream processing operations such as magnetic separation, flotation, and pelletization.
