Justin Klinger, Jun 16, 2022 9:22:00 AM. Nanonization (sometimes also called nanoization) refers to the processes used to make particles that range in size from 1 nanometer (nm) to 100 nm. Many biological processes are nanoscale. In the human body, hemoglobin measures about 5.5 nm in diameter. DNA is even smaller — one strand measures just 2 ...
A ball mill is a type of grinder used to grind or blend materials for use in mineral dressing processes, paints, pyrotechnics, ceramics, and selective laser sintering.It works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell. A ball mill consists of a hollow cylindrical shell rotating about its axis. T

A change in particle size effects a change in power. The power dropped 8 percent in grinding from one-half on 14-mesh to the same amount on 48-mesh. By using a charge with a much coarser particle size and not continuing the run too long the test could have been devised so that the power range would have been reversed.
The particle size distribution was observed after 20, 40, 60, 80, 100, 150, 200 and 300 ball mill revolutions. The energy input was calculated from the net torque (corrected for the torque for the empty mill) and the number of revolutions. For light ball loads the ball mill is less efficient as might be expected.
