TECHNICAL NOTES 8 GRINDING R. P. King Mineral Tech

Slippage will consume energy wastefully but more importantly it will reduce the ab ility of the mill shell to transmit energy to the tumbling charge. This energy is required to cause grinding of the material in the mill. The shape and dimensions of the lifters control the tumbling action of the media.

EIA Greenhouse Gas Emissions Methane Emissions

EIA Greenhouse Gas Emissions Methane Emissions

Natural gas systems and coal mines are the major sources of methane emissions in the energy sector (Figure 18 and Table 18). methane emissions from natural gas systems grew from 1990 to 2009 by 27 percent (39 MMTCO 2 e), largely because of increases in natural gas consumption. Emissions from coal mines declined from 1990 to 2002 and remained nearly steady through 2007.
