The basic principle for rod grinding is reduction by line contact between rods extending the full length of the mill, resulting in selective grinding carried out on the largest particle sizes. This results in a minimum production of extreme fines or slimes and more effective grinding work as compared with a ball mill.

That's the point of coal, to encourage you to play everyday. It's not designed to be a "grindable" currency like FXP is. It is "grindable," really, it's just that there is a cap on how much you can grind in a day; it's just not open-ended. 400 per day if he doesn't take the resource containers, 1600 if he does.

The thickness of a grinding wheel impacts its performance and wheel life. Our grinding wheels typically come with a quarter-inch thickness. This measurement gives our wheels a superior balance of precision, wheel life, and cut-rate when grinding. Combination grinding and cutting wheels with 1/8-inch thickness are also available.

Volatile matter (VM) is the percentage loss in mass, adjusted for moisture, when coal is heated out of contact with air under standard conditions. In this test, 1 g of sample is placed into a lidded crucible (to prevent ingress of air), which is placed in a furnace at 900 °C for 7 min or 950 °C if using the ASTM method. Moisture in the analysis sample is determined concurrently.
