Validation process of ball mill a novel technology for minimizing the synthesis time of 2014618a novel technology for minimizing the synthesis time of nanostructured powders in planetary mills majid abdellahi a is a ball milling process where a powder mixture placed in a ball mill is subjected to highenergy collision from

Mill power usually plant operators use mill power readings as an indicator of ball filling degree and often try to keep it at the maximum level it is well known that the mill absorbed power depends on operating parameters other than ball level such as pulp density and liner configuration figure 2 shows that there is no linear relation between

A power analyser was utilized to measure mill power increase in mill speed and ball filling leads to a remarkable increase in the amount of the power preliminary results show that there is a definite trend between the power and the slurry filling u mill power draw is maximum at slurry concentration 6070 and slurry filling 084

Ball mill critical speed working principle youtube 19062015 ball mill critical speed working principle that power draw will vary with different original liner designs as well as throughout the wear life depending on the wear pattern and secondly mine graveyard used mining machinery australia
