Get QuoteMar 01, 2001 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.
