Users can transfer desired shapes from CAD drawings into G code, which the DM 9CNC reads to form the wheel.
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.
Coal grinding to a fineness of 200 mesh (90 percent) is necessary to assure maximum efficiency and to minimize the deposit of ash and carbon on the heat absorbing surfaces. Exhausters and Blowers— If the pulverizer operates under pressure the primary air fan handles clean air and is not abraded by the pulverized coal.
Coal is still used in approximately 90 of cement plants globally to deliver the energy needed for the heat inside the kiln. Online coal analyzers using PGNAA technology are used to control the coal blend to a specific GCV in addition to the ash value of the coal as this adds raw materials to the process as well.
