- Processing Run Of Mine Crushers
Even when a crusher has the capability of achieving a high reduction ratio it is normally more efficient to run the crusher at a mid-setting, as shown in the manufacturers tables, rather than choosing the closest setting which offers the greatest reduction ratio. The main consideration at each stage for maximum production is efficient power draw.

The most common types of crushers include Jaw Crushers, Gyratory Crushers, Cone Crushers, Impact Crushers, Roll Crushers and Hammermill Crushers. Compression crushers, such as Jaws, Gyratories, Cones and Roll Crushers, reduce material by squeezing or compressing it between a moving piece of steel and a stationary piece of steel.

For example, in the open-pit mine production scheduling, the main aim is to optimize how the material should be extracted from the open-pit mine, while considering mine block models and other restrictions. Stockpiles are used as a component to maximize the net present value and to maintain lower-grade valuable material for future processing [13 ...

The process of crushing coal to a more manageable size is an important step in the processing chain. Primary crushers reduce a wide range of large Run of Mine (RoM) coal to either a marketable product or a range that can be more easily handled by the preparation plant. More recently, as large mines try to crush RoM coal to a saleable product ...

Run-of-mine ore is usually too large to be useful for construction or metallurgy. Large particles must be reduced to specific sizes to either comply with aggregate sizing regulations, or facilitate mineral liberation; therefore, in the aggregates and mineral processing industries, run-of-mine ore is broken in crushing circuits by cone crushers.

Gyratory crushers were invented by Charles Brown in 1877 and developed by Gates around 1881 and were referred to as a Gates crusher [1]. The smaller form is described as a cone crusher. The larger crushers are normally known as primary crushers as they are designed to receive run-on-mine (ROM) rocks directly from the mines.
