A Technical and Economic Comparison of Ball Mill Limestone
2021.10.13 A pilot-scale Loesche VRM was used to determine the power required to grind 100 t/h of the same limestone as used at Kusile (work index of 12 kWh/t) with a top size of 19 mm to a 85% and 95% passing 45 µm product. A significant power saving of 39.2% was observed for the dry VRM compared to the wet ball mill (37.7% for the circuit).

Estimation of the Specific Energy Requirement for Size Reduction
2016.11.8 where \(y_{p}\) is the 80% passing size of the mill product, \(y_{f}\) is the 80% passing size of the mill feed, C is a mill-material constant, and α is the exponent of particle size (its significance discussed in detail later). It has been shown [] that the value of the exponent α varies strongly with the material type, generally in the range of 0–2.

Selected Advances in Modelling of Size Reduction in Ball
2023.9.22 chemical industries are subjected to grinding in ball mills [1–3]. The specic energy consumption for these materials typically ranges from 5 to 50 kWh/ton. Thus, the ball mills consume an enormous amount of energy. The energy e-ciency of the ball mill being as low as 1% or less [2], there is considerable incentive to improve the energy eciency.
