Ball mills tumble iron or steel balls with the ore. The balls are initially 5–10 cm diameter but gradually wear away as grinding of the ore proceeds. The feed to ball mills (dry basis) is typically 75 vol.-% ore and 25% steel. The ball mill is operated in closed circuit with a particle-size measurement device and size-control cyclones.
Ball bearings are one of the most common types of bearing classes used. It consists of a row of balls as rolling elements. They are trapped between two annulus shaped metal pieces. These metal pieces are known as races. The inner race is free to rotate while the outer race is stationary.

The biggest characteristic of the sag mill is that the crushing ratio is large. The particle size of the materials to be ground is 300 ~ 400mm, sometimes even larger, and the minimum particle size of the materials to be discharged can reach 0.1 mm. The calculation shows that the crushing ratio can reach 3000 ~ 4000, while the ball mill's ...

lubricated bearing varies with the type and size of bearing: with a high-speed angular contact ball bearing, the d mn value should be 140×104 as a guideline. For applications exceeding this range, consult NTN Engineering. Grease types A lithium-based grease, whose base oil is mineral oil, is commonly used as a lubricant for rolling bearings, as
The axial bearings used in these mills are angular contact ball bearings or deep groove ball bearings. In back-up rolls for large four-high hot strip mills, a deep groove ball bearing is often sufficient as an axial bearing. It generally has the same section height as the radial cylindrical roller bearing to which it is allocated.
Planetary ball mills are the most popular mills used in scientific research for synthesizing MgH 2 nanopowders. In this type of mill, the ball-milling media have considerably high energy, because milling stock and balls come off the inner wall of the vial and the effective centrifugal force reaches up to 20 times gravitational acceleration.
