Lead oxide, which has a lamellar structure, is produced in a ball mill and is usually preferable due to its larger specific surface area compared to spherical particles. Therefore, the oxide from the Barton reactor is subjected to a hammer mill grinding process in order to increase the specific surface area.

where d b.max is the maximum size of feed (mm); σ is compression strength (MPa); E is modulus of elasticity (MPa); ρb is density of material of balls (kg/m 3); D is inner diameter of the mill body (m).. Generally, a maximum allowed ball size is situated in the range from D /18 to D/24.. The degree of filling the mill with balls also influences productivity of the …
