To illustrate how grinding conditions can affect ball mill efficiency, the batch grinding model will be used to model closed-circuit ball milling of the soda-lime glass. For this model, the size range of a particulate assembly in a batch mill is divided into size intervals with a maximum size X 1 above and a minimum size X n+1.
The mill type and process system play an impor-tant role. Intergrinding (co-grinding) in classical ball mills (closed system) leads to a broad PSD, which is The motives to replace clinker with supplementary cementitious materials (SCM) are well known. However, granulated blast furnace slag, natural pozzolanes, qualified fly ash and

We feature a great selection of used ball mills from top brand name manufacturers including , FL, Outotec, Kobe Allis, , Hardinge & Denver. Rod mills are very similar to ball mills but instead of using grinding balls they use long steel rods to do the media grinding. Some miners believe that rod mills are more efficient than ...
To have a pulp as dilute as 20 percent solids, the ball load was drawn down to 30 percent volume and the ore charge proportionately reduced. Water was then added to fill the mill. The results of grinding were much like those with 33 percent solids. All in all, 33 percent solids was the best for efficiency and selective grinding.
