Henan YuFeng Heavy kiln manufacturers in this introduction more about some of the problems and their causes rotary 
equipment appear in the production, describes the causes cracks, spokes , journal about the occasional round of fracture 
appeared today . 1 cylinder centerline is not straight , so occasional round of excessive force overload ; ( ADS force 
observation wheel contact surface ) poor care axle 2 material, internal defects, insufficient strength , fatigue resistance is 
poor; .. 3 -axis neck stress concentration , vertical combination crusher      skew is too large, too large thrust bearing ; 4 long-term cooling irrigated , 
leaching , resulting in instant noodle crack, spalling ( also affects tire ) on the kiln roller kiln production is very important part 
, but often encounter some issues related to this , do regular inspection and timely detection of problems and accurately 
solve problems and ensure efficient production of conduct .
