For example, the bulk density of worn rods after a specific time of grinding would be 5.8 t/m 3 for a 0.91 m diameter mill. Under the same conditions of operation, the bulk density would be 5.4 t/m 3 for a 4.6 m diameter mill. During wet grinding, the pulp charged to the mill is usually held between 60 and 75% solids by mass.
