Rock Crushing Rule of Thumb

Crusher Design. The approximate capacity of a jaw crusher for hard rock application at a typical setting may be obtained by multiplying the width by 10 to get tonnes per hour. For example, a 48 by 60 crusher will have a capacity in the order of 600 tph when crushing ore in a hard rock mine. Source: Jack de la Vergne

Choosing the right crusher

A cone crusher can crush a variety of rocks, from medium to hard. The way a cone crusher operates is similar to how a gyratory crusher does, but in a cone crusher the slope in the breaking space is not as steep. Although it is known for its ability to crush hard and abrasive ores and rocks, the cone crusher is better suited for secondary crushing.

Modelling of flow in cone crushers

To calculate the output from a cone crusher, models for size reduction and flow are needed. The interaction between these two models is quite complex as the overall size reduction in a cone crusher is a result of a repeated consecutive comminution process. The flow model is important since it describes how the rock material moves through the ...
