## Slurry Velocity In Ball Mill

#### MODELLING THE INFLUENCE ON POWER DRAW OF THE SLURRY .

Shape for Grate Mills (no slurry pool) Shape for Overflow Mills . 2. Model Structure . General . As per Morrell's original model structure the grinding media part of the charge (rocks and/or, ball) is configured as per Figure 3. When a mill is in operation the slurry portion of the charge occupies the grinding media interstices.

#### Slurry Density

Slurry is a mixture of a solid and a liquid. The density of a slurry can be calculated as. ρ m = 100 / [c w / ρ s + [100 c w] / ρ l] (1). where . ρ m = density of slurry (lb/ft 3, kg/m 3). c w = concentration of solids by weight in the slurry (%). ρ s = density of the solids (lb/ft 3, kg/m 3). ρ l .

#### Prediction of slurry transport in SAG mills using SPH ...

The porous media properties (specifically the spatial distribution of porosity and velocity) are predicted by time averaging the mill charge predicted using a large scale DEM model. This allows prediction of transient and steady state slurry distributions in the mill and allows its variation with operating parameters, slurry viscosity and slurry volume, to be explored.

#### Towards a Poolbased Model of Volumetric Slurry Holdup ...

· The data included information on ball filling, slurry holdup, mill speed, mill internal volume, shoulder, and toe angles of the media charge, as well as slurry pool angle. Initial results showed that the proposed empirical model fitted well the data not only from the three mills but also from an independent source.

#### Slurry pumping in a vertical pipe

· I am pumping an iron ore slurry approximately 60' through a vertical pipe. After calculating the limiting settling velocity I have found the actual velocity to be roughly 1 ft/sec slower than the settling velocity, I am trying to avoid dropping pipe size due to a drastic rise in velocity.

#### How Slurry Transport inside a Tumbling Grinding Mills

· The transport of slurry within the ball mill depends on the peripheral velocity and porosity of the ball charge. Residence time distribution and mill hold up are often used as indiors of the mode of transport. In this work, the transport problem is tackled via direct simulation of the three dimensional motion of the ball charge.
