Mar 19, 2009· Historically, a dram was a coin, a unit of mass, and a unit of volume. For volume, it's an eighth (1⁄8) of a fluid ounce. If you're using a speed pourer, like they have in bars, you get about an ounce and a half in three seconds. For a dram, that's a pour of a quarter of a second. If you think of it in those terms, it's really not that much.

Mine water must be removed from operating mines to prevent flooding, the removal rate equaling the inflow rate. Except for cases in which the mine is elevated above the sur­ rounding topography, mine water must be pumped to a treatment system or to a dis­ charge point. Energy consumption can be sig­ nificant, not only because of large volume ...

Anemometer Instrument for measuring air velocity. Angle of dip The angle at which strata or mineral deposits are inclined to the horizontal plane. Angle of draw In coal mine subsidence, this angle is assumed to bisect the angle between the vertical and the angle of repose of the material and is 20° for flat seams. For dipping seams, the angle of break increases, being ° from the vertical for a 40° dip.

Ball Mill Loading Dry Milling. Ball Mill Loading (dry milling) When charging a ball mill, ceramic lined mill, pebble mill, jar mill or laboratory jar use on a jar rolling mill it is important to have the correct amount of media and correct amount of product.
