Li security safeguards mill

Li mills start operation: 1 Start vertical roller mill integrated control cabinet; 2 Start coal transportation group, start collecting bags of coal mill group, before the group starts and runs in both to ensure adequate air pressure (> 0.5Mpa); 3 Start the coal mill main exhaust unit, by adjusting the dampers to control the degree of opening of the mill preheat the heating process (particularly heating operations, see below); 4 Start coal transport group (this group at any time based on coal power Hoppers and production), after the end of the maintenance or downtime must confirm the good points of each cutting feed slot cover slip and indeed before the normal boot, while coal must Netted bunker on clean; 5 when the legislation after the mill can be opened fully preheated coal mill and coal feeder main motor group, after the mill started to pay attention to the main vertical grinding mill motor current, vibration and other parameters, depending on the circumstances mill current, differential pressure and vibration adjust the volume of feed dosing machine, while adjusting the dampers opening, ensure the stable operation of the mill; 6 adjust the parameter should be small amplitude, avoid big ups and downs, in addition feed reduction, we must change the corresponding mill ventilation to allow the system to reach equilibrium;
