yes, since the coal pulverisors/coal mill are engaged only at specific times depending upon loading of unit, say at 20%, 40%, 60% and last at 80% of a 500 mw plant, i am also deducing that bfp ,air flow and duty on fd, id fans and even cooling tower requirements also discretely increase with opening of coal mills at these intervals. as with more coal to burn all other needs are bound to increase though they may be disproportionate with unit loading..modelling of vertical spindle mills. part 1: sub-models,the machine specific variables include mill geometry, air classifier geometry, coal feed rate, primary air flow rate, air temperature, air pressure, grinding table rotational speed, mill spider hydraulic load and mill power draw. these variables are incorporated in the comminution and classification functions based on physical principles..b&w roll wheel pulverizers - babcock,b&w’s auto-spring™ pulverizer loading system controls roll wheel loading on-line based on the coal feed rate. as a result, the auto-spring loading system can extend the turndown range. it allows improved high load pulverizer performance while maintaining important low load operating capability. the springs allow the rollers to move with the.analisa kebocoran pada body mill / pulverizer …,loading method of grinding roller : hydraulic variable loading nameplate troughput 38.5 t/h rotating speed : 24.2 r/min oultet temperature : o65 c fineness if coal powder : r 90 =30% max ventilation resistance of coal pulverizer : 6.41 kpa quantity : 6/boiler
