However, other factors such as coal hardness (i.e. the lower the Hardgrove Grindability Index, or the harder the coal, the higher the power consumption) and mill throughput (i.e., the higher the throughput, the higher the power consumption) had to be included before the impact of grind size could be isolated.
Roll presses are also used in, particularly in upgrading existing ball mill circuits as pre-grinders to increase production or to reduce specific power consumption in grinding operation. Ball mills for cement raw material and coal equipped with a drying compartment adequately air swept with hot gas (2.5-3.5M/sec above the ball charge), can ...
Dec 18, 2013· Fine grinding, to P80 sizes as low as 7 μm, is becoming increasingly important as mines treat ores with smaller liberation sizes. This grinding is typically done using stirred mills such as the Isamill or Stirred Media Detritor. While fine grinding consumes less energy than primary grinding, it can still account for a substantial part of a mill's energy budget.

Nov 17, 2012· Specifically, fineness is a measurement of the percentage of a coal sample that passes through a set of test sieves usually designated at 50, 100, and 200 mesh A 70% coal sample passing through a 200 mesh screen indicates optimum mill performance. The mill wear and the power consumption are increased if the 70% value is exceeded. Values lower ...
The mill wear and the power consumption are increased if the 70% value is exceeded. Values lower than 70% mean higher carbon loss and increased fuel consumption. In addition, coal retained on the 50 mesh screen should be in the 1–2% range. Higher values indicate worn internals or improper settings.
