  What is the difference between a SAG mill and ball mill?

  A SAG mill with a 44′ () diameter and a power of 35 MW (47,000 HP) has been designed. [9] Attrition between grinding balls and ore particles causes grinding of finer particles. SAG mills are characterized by their large diameter and short length as compared to ball mills. The inside of the mill is lined with lifting plates to lift the material inside the mill, where it then falls off ...

  Preventive Maintenance and IIoT for Ball Mills

  Pinions and Bearings. The primary points of friction are in the pinion, main, or trunnion bearings. Again, data from these components is essential to know if you want to understand the health of your ball mill. Drilling and threading an NPT hole and adding a vibration sensor could very well save you hundreds of thousands of dollars.

  Ball Mill Explained

  Multiple stages may include a rod mill followed by a ball mill (two stage circuit), or a semiautogenous grinding (SAG) mill followed by a ball mill (two stage circuit). Smaller plants tend to add extra crushing stages in order to operate a single grinding stage only. If a ball mill uses little or no water during grinding, it is a ''dry'' mill.
