Oct 21, 2018 Systems injecting this coal size are termed granular coal injection (GCI). The coarser grinding has the advantage of lower grinding and drying costs with the ground coal easier to handle. The finer grinding has a higher burnout in the raceway. PCI is popular technology than the GCI. Coal fineness can be varied in the pulverizer by a number.With further regard to the matter of the pulverizing, i.e., grinding, action to which the coal disposed on the grinding table 18 is subjected by the grinding rolls 22, the amount of force that must be exerted by the latter in order to effect the desired degree of pulverization of the coal will vary depending on a number of factors.
Oct 01, 2011 Pulverizer “capacity” is the amount of coal a pulverizer can grind at a given raw feed rate, to a given fineness, at a certain Hardgrove Grindabilty Index (HGI), and at a specific raw fuel.An impact pulverizer is widely employed for dry milling of powders in many industrial sectors. However, effect of the equipment geometry on grinding performance of the impact pulverizer is still.
