slurry flow through a ball mill

Effect of Slurry Solids Concentration and Ball Loading on

flow through the mill is fundamental in trying to improve the efficiency of wet milling circuits. For a given set of operating conditions the flow behaviour of slurry within the mill determines the slurry residence time inside the mill and consequently the holdup volume both of which have a large influence on the milling efficiency.get price



How Slurry Transport inside a Tumbling Grinding Mills

The transport of slurry through the ball-bed in tumbling mills depends on the distribution of voids inside the charge and the speed of the mill. When balls of different sizes are present in the mill then there is a tendency for the balls to move at different speeds along the axial direction.get price
