Primary Coal Crushers Grow to Meet Demand
Crushing screened feed generated a product with the fewest fines. Compared to the screen/ Flextooth system, the two stage double roll crusher product with screened feed contained nearly 30% less fine coal. Based upon the results of the study, the system was replaced with a screen/two stage double-roll crusher system.
