Capacity of highpressure grinding rolls | SpringerLink
May 01, 1995 · Six US coals and a crystalline quartz were tested in an instrumented laboratory highpressure grinding rolls machine equipped with 100mmdiam. rolls. The machine was chokefed to maximize the capacity. As expected, the specific capacity decreased with increased grinding pressure for each material tested. Among the six coals, there were significant differences in the critical angle of .
