With life. Operation, the speed can be adjusted through the grate bed, keep the grate plate feeding layer thickness, reasonably adjust the grate type high pressure cooling machine, medium pressure fan air volume, thanks to raise two or three times the wind temperature. When thick bed material, should speed up the bed operation, up high pressure fan damper, get into the high temperature clinker cooling machine always being loose state. And appropriate level of medium pressure fan inlet, in order to reduce the amount of exhaust gas cooling machine; When analysis on material layer is thinner, the lower the air pressure can be overcome and blowing through material layer resistance short-circuit phenomenon, clinker formation clinker cooling effect is poor, for the wind to avoid short circuit, the speed can be appropriate to slow down the bed, close the high-pressure blower inlet, the appropriate, medium voltage fan damper for improving the efficiency of cooling
