Causes of cracks in the half-gear of Coal Grinding Mill

The Coal Grinding Mill has problems during the use of the equipment, affecting the normal production of the equipment. After inspection, it was found that the half gear produced cracks. What is the cause of this phenomenon? SBM dispatched a dispatch technician to the site for on-site inspection.

After inspection, it was found that the cause of the crack of the half-gear of the Coal Grinding Mill, in addition to the structure of the half-gear of the Coal Grinding Mill, there are mainly other reasons.

First, due to the need for feeding, the riser is placed on the inner edge of the gear, and the riser increases the mechanical obstruction stress and thermal stress of the Coal Grinding Mill during the cooling of the casting.

Secondly, when the inner edge of the oxygen cutting wheel rises, the thermal stress is increased, and when the Coal Grinding Mill cuts, the temperature of the riser part on the inner edge of the wheel is high, and the weak part of the strength of the other parts of the Duyu wheel is generated.

It is concluded that the generation of cracks in the half-gear of the Coal Grinding Mill and the increased obstruction stress and thermal stress of the riser parts of the wheel are not removed. The reason for finding the right medicine is that the SBM has repaired and modified the half-gear structure of the Coal Grinding Mill and the inner edge of the wheel, and received good results, which have been recognized and praised by users.
