Comparison of energy efficiency between ball mills and …

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 high, and size reduction efficiency is low.

Empirically, It can be estimated through a simple heat balance that in ball mills only 10% of the energy is used to increase cement fineness, the rest being dissipated basically in form of heat. A VRM allows the exploitation of around 30% of the energy supplied: this results in a lower energy consumption, in terms of kWh/t.

A systematic study of energy efficiency of comminution (Fuerstenau, Lutch, & De, 1999) revealed that the energy consumed to achieve a reduction ratio of 30 using the hybrid HPRM with ball mill system was only about 70% of that required by ball milling alone. An additional aspect of energy reduction with the hybrid system is utilisation of the ...

Oxygen-vacancy-mediated energy transfer for singlet oxygen generation

Therefore, the remaining possibility for the generation pathway of 1 O 2 in the MIL-125-AA system was energy transfer. Since energy transfer between the singlet state of sensitizers and the ground state of O 2 is spin forbidden, the generation of 1 O 2 relies mainly on the energy transfer from the triplet states [53, 58].
