coal sizing and crushing

  • Coal comminution and sizing ScienceDirect

    Coal sizing: an introduction. After crushing with rotary breakers, crushing rolls, or other primary coal breakage machines, most coal processing plants will screen the coal into multiple size fractions for processing. Each of these size fractions is then Micro shape of coal particle and crushing energy,Using the least square method, we can obtain the following fitting expression: (13) S = a bc E where S is the new surface area for particles below 0.075

    The purpose of crushing is to decrease the Run of Mine (ROM) coal to a size appropriate for washing, and size reduction involves a variety of concepts such as compression, impact, shearing, splitting, and attrition. Primary crushers are typically intended to accept ROM coal and crush it to a top size of 2″ to 8″.Coal, sizing Big Chemical Encyclopedia,Coal, sizing Pulverization occurs by impact, attrition, or crushing. The capacity of a pulverizer depends on the grindability of the coal and the fineness desired, as shown by Fig. 2719. Capacity can also be seriously reduced by excessive moisture in the coal, but it can be restored by increasing the temperature of the primary air. Figure 27
