Kolev et al (2021) –In press. Improving the energy efficiency in tumbling mills with the use of Relo grinding media (MDPI) • Lab trials conducted using a standard Bond ball mill (@ Wardell Armstrong) • Standard Bond ball mill procedures were followed –only the RELO media PSD and mass of charge adjusted to match spherical media
Improving the grinding efficiency in tumbling mills is essential to minimising comminution energy consumption. Over the years, fundamental insights gained from ball mill operation provided energy-efficient routes to increase throughput and reduce product grind size distributions through optimisation strategies.
Beside lower ball charge will increase P80 of ball mill because of less number of impacts but mean residence time will increase by lower ball charge because of more volume to occupy. I think at last in this situation, power consumption will increase. ... Ball mill liner efficiency based on liner geometry and its influence on kW-hours/ton, total ...
It was also observed from the experimental results that in order to increase the milling efficiency of a ball mill, towards optimum production of material in the desired size class, there is a need to correlate the ball size and the feed size distributions. ...
