03 Ball Mill EDM - Mill (Grinding) - Gear

 · A further conclusion from [2] is that the pinion diameter is more important that gear blank profile (Y or T). So, according to [2], the failure of those gears was caused by a design fault, i.e., the diameter of the pinions in the Cadia ball mills are too small. Figure 2: Model of gear contact in [2] - similar to a spur gear, not a helical gearOur automatic production line for the grinding cylpebs is the unique.
