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.

A ball mill also known as pebble mill or tumbling mill is a milling machine that consists of a hallow cylinder containing balls; mounted on a metallic frame such that it can be rotated along its longitudinal axis. The balls which could be of different diameter occupy 30 – 50 % of the mill volume and its size depends on the feed and mill size.

Both studies clearly show the potential of the highly efficient ball-milling method for the fabrication of SACs for use in catalysis areas. The atomic layer deposition (ALD) technique is a gas-phase chemical process and commonly used to deposit a thin layer of film in a bottom-up fashion with near-atomic precision on the substrate by repeated exposure of separate precursors [ 85 ].
