An excessively high rotation speed will shorten the effective impact distance, reduce the coal crushing depth, and lower the coal crushing efficiency. On the other hand, as can be known from the analysis in the previous section, an upper limit exists for the depth of coal crushing by the same equipment under a constant pump pressure.

The coal is then fed to the HMV through the Feed Manifold. The depth that the feed is injected should be minimized to avoid possible bypass of light particles to the tailings stream. A feed sink plate is used to direct the feed downward into the vessel so that particles do not raft across the width of the bath.

Dec 15, 2017 How coal is mined. In 2016, the United States burned roughly 728 million tons of coal, enough to fill a typical railroad car every 4 seconds .The electricity sector accounted for over 90 percent of all coal used in the United States, with the rest burned in industrial and commercial settings.
May 27, 2010 The overall coal plant efficiency ranges from 32 to 42 . This is mainly dictated by the Superheat and Reheat steam temperatures and Superheat pressures. Most of the large power plants operate at steam pressures of 170 bar and 570 C Superheat, and 570 C reheat temperatures. The efficiencies of these plants range from 35 to 38 .
