Why Flute Count Matters
The 25% increase in material removal is more likely closer to 10-15%, given the tool is exactly the same in all other specifications. Higher flute count tools may require speeds and feeds to be backed off so much in some cases, that a lower flute count may be even more efficient. Finding the right balance is key in modern milling practices.

Open letter on the boiler and mill problems at Medupi and Kusile – EE
To counter this, Eskom needs to pulverise our coals much finer than required elsewhere, in order to compensate for the slower burn-rate. In the case of the boilers for Matimba, Kendal, Majuba and Lethabo, I insisted on furnaces of larger dimensions, as well as the use of tube mills in place of previously-used vertical spindle rotating table mills.

Ball Mill
Ball mills tumble iron or steel balls with the ore. The balls are initially 5–10 cm diameter but gradually wear away as grinding of the ore proceeds. The feed to ball mills (dry basis) is typically 75 vol.-% ore and 25% steel. The ball mill is operated in closed circuit with a particle-size measurement device and size-control cyclones.
