2021-3-24 In this paper a new digital energy meter is being evaluated as a means of measuring the energy required to grind ore in the Bond mill and to test if the results are consistent with Bond's original methodology. The specific comminution energy for milling in the Bond test mill appears to be based on 60 J/rev, which defines the net energy required in the Bond ball mill to realise the same ...

ABSTRACT Owing to the lack of effective energy consumption models of ball mills in the ceramic industry, a calculation model to forecast energy consumption of ceramic ball mills during the grinding process was developed based on power feature deployment. The energy consumption of the working process was defined by different combinations of power of components involved in tasks.
