This means that during one rotation of the sun wheel, the grinding jar rotates twice in the opposite direction. This speed ratio is very common for Planetary Ball Mills in general. Planetary ball mills with higher energy input and a speed ratio of 1:-2.5 or even 1:-3 are mainly used for mechanochemical applications.
— Because of its ability to withstand the severe impact conditions such as those experienced in the large diameter ball mills, the high manganese steel became the focus of many of the early investigations [5], [6]. The steel, which has a low initial hardness (approx. 200 BHN) is also expensive to produce. High chromium cast irons ... Wet milling ...

— The difference in material itself: the material of the forged-rolled steel ball is high-quality round steel or high-quality composite steel, and its C content is less than 1.4, so it is called steel ball after forging and rolling; while the basic material of cast ball is scrap steel, which is smelted.
Data from full scale marked ball tests are used to demonstrate the effects of abrasion, corrosion, and impact on overall wear rate. The predominate wear mechanism need be identified before the optimum alloy can be chosen for the grinding media. Use of high chromium grinding media often results in increased mill efficiency due to shape …
High chromium alloy cast steel: the ball mill liners made of this material is widely applied, which can be used in large, medium, and small-sized ball mills, and can be used in both the coarse grinding bin and the fine grinding bin. It is especially suitable for the mill which uses high chromium cast balls as the grinding media.
