THE CRUSHING OF ANTHRACITE WITH AN IMPACTOR-TYPE CRUSHER
The products were screen analyzed using round hole screens and plotted on a Rosin and Rammler graph paper. Standard anthracite sizes were determined from the aforesaid curves. An analysis of the results indicated that a low rotor speed of 620 RPM and a low feed rate of 5. 9 ± 0. 1 gave the best results for the crusher tested.
