The working environment of ultrafine vertical mill is bad, so it is hard to avoid some failures. These faults not only affect the normal performance of mill efficiency, but also greatly reduce the service life of mill parts and lubricants, and increase the consumption of spare parts and materials, which increases the labor intensity of maintenance and production. Therefore, the reasonable handling of these faults can ensure the stable operation of ultra vertical mill and improve the production efficiency.

Big and small bevel gears are worn and broken

reason:

1) The normal meshing condition of bevel gear is destroyed

2) Rigid connection transmission

3) Too much iron or being bitten by large pieces
