The Emax is an entirely new type of ball mill for high energy milling. The unique combination of high friction and impact results in extremely fine particles within the shortest amount of time. faster and finer grinding than any other ball mill. speed of 2000 min -1 allow for ultra-fast pulverization of the sample.
Limestone grinding preparation and desulfurization grinding equipment are essential components in the flue gas desulfurization (FGD) process used in coal-fired power plants. The process involves the use of limestone or lime to remove sulfur dioxide (SO2) from the flue gas, which is a major pollutant emitted by burning coal. ... - Ball Mills ...
2.1.2. Filler. This study used limestone aggregates from a local quarry with a nominal size range of about 2.36–4.75 mm.
