Wet bond mill test

2001-3-1 · 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.
