The material conveying work of the fan in tandem with the entire processing of corn, if it can not play its own role, it will lead to errors and problems in processing work. So in order to avoid losses, the failure of the fan is necessary to solve, but there are many reasons for the failure of the fan, we need to first understand to the corn milling machine equipment to clear.

　　The first is the design reason, corn milling machine equipment appear improper design, unreasonable structure, speed close to or fall into the critical speed zone.

　　The second is the manufacturing reasons, processing precision is not enough, poor material, not enough strength, manufacturing defects, rotor dynamic balance does not meet the technical requirements.

　　The third is the corn milling machine equipment installation reasons, improper mechanical installation, component misalignment, improper parameter adjustment, machine working condition change, dynamic balance accuracy change or the original with the nature and accuracy of the change and so on.

　　The fourth is improper operation and running, such as corn milling machine equipment parameters deviate from the design value, over speed, overload running, running point close to or fall into the critical speed zone or poor lubrication or cooling, impeller damage or scaling, uneven thermal expansion or stay in the critical zone for too long.

　　The fifth is the wear and aging of the corn milling machine equipment, long-term operation, increased rotor deflection or dynamic balance deterioration, rotor local damage, shedding or cracks, parts wear, pitting or corrosion, machine shell deformation, etc..
