HIGmill energy efficient fine grinding - Metso Outotec

2018-4-4  Energy Efficiency. A large metalliferrous concentrator HIGmill was equipped with the flat discs. In order to improve efficiency of the power draw and prolong the life of the discs, GrindForce rotors were installed into the mill. Immediately after the installation of the castellated rotors, a benefit in the energy efficiency was observed.

Comparison of energy efficiency between ball mills and ...

2009-6-1  At product sizes finer than 80% passing 75 μm, the efficiency of ball mill grinding rapidly decreases. The practical limit to ball mill product fineness is considered to be 40–45 μm (Gao and Weller, 1994). Although ball mills can still be found in the regrind circuits in a number of mineral processing plants, their energy consumption is ...

2016-2-16  energy-efficient grinding technologies such as stirred mills in platinum concentrator circuits. In addition to this, further energy gains can result, depending on how this technology is incorporated in a flowsheet. For instance, in some cases a two-stage stirred milling circuit will use energy more efficiently than a single-stage option.

Quantifying the energy efficiency of fine grinding ...

In previous publications, we have described how the size specific energy (SSE) can be calculated to predict the energy required to generate new minus 75 µm material. However, if we want to benchmark the performance of fine grinding where the product can be much finer than 75 µm, clearly we require a finer marker size. If we do this, we also need a way to compare results that
