Coal comminution and sizing

While hammermills can be used to produce coal with a topsize on the order of a few millimeters, when they are used to crush feed for a coal preparation plant they crush to sizes on the order of 2 inches (5 cm). Such coarse hammermills have capacities of up to 2500 tons/h (2270 metric tons/h) (Alderman and Edmiston, 2010).

CRUSHING SOLUTIONS FOR ROM SIZING

depending on the mining and transport methods the first crushing stage may require crushing of ROM coal to a size of less than 50 mm (typically for low and medium throughput rates) to 250 mm (for higher throughput systems). A larger product size can be used in primary crushing to avoid over dimensioning of crushers with high throughput rates.
