The diaphragm arrangement in a ball mill is a positive means of pumping pulp or dry material out of the mill. The gradient is steeper than in an Overflow type mill. A Diaphragm ball mill has a higher capacity and requires more power than an Overflow ball mill of equal ball charge.
This is the instantaneous residence volume for pulp. Next compute the volumetric flow of slurry into your mill, as m³/h or L/s (match whatever volume units you used in the first step). Now divide the instantaneous volume by the vol flow (cancelling the vol units) and you are left with time units; this is your residence time.
Grinding in ball mills is an important technological process applied to reduce the ... time, the mass fraction in size 1 will disappear as the particles are broken and distributed in the smaller sizes. It should be noted however, that the total mass remains constant. Fig. 3
According to the ball mill survey database presented in Section 4, the volumebased residence time of slurry in an overflow ball mill should be greater than 2 min for a less than m diameter ball mill, and 1 min for a larger than m ball mill.
