Ball Mills. Our combined experience in ball mill design and process equipment development totals more than 60 years and allows us to put a unique spin on steel and lined mills. Particle size reduction of materials in a ball mill with the presence of metallic balls or other media dates back to the late 1800's.
2.1.2 Critical Speed: If the peripheral speed of the mill is very high, it begins to act like a centrifuge and the balls do not fall back, but stay on the perimeter of the mill and that point is called the "Critical Speed" (n c).This phenomenon is called centrifuging. Ball mills usually operate at 65% to 75% of the critical speed.
