The lockedcycle (multistage) grinding test was developed by Man (1999) as one major component in the new ball mill scaleup procedure. The test procedure is the same as the wellknown Bond ball mill grindability test (Bond, 1961). In the Bond ball milling test, the fresh feed to the test is crushed down to passing mm.

where d 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 mill and milling efficiency.

Wet bond mill test 371 The ball mills operate at a pulp density of approximately 40% solids by volume (Wills, 1992). However, the viscosity of the pulp (density) increases with the fines of the particles, therefore fine milling requires a lower pulp density. As a result of this, a pulp density of 30% solids by volume should be chosen for the tests.
