أكمل القراءة· 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.
أكمل القراءة· In the mine, coal is loaded in small coal cars or on conveyor belts which carry it outside the mine to where the larger chunks of coal are loaded into trucks that take it to be crushed (smaller pieces of coal are easier to transport, clean, and burn). Th e crushed coal can then be sent by truck, ship, railroad, or barge.
