PREDICTION OF COAL SLURRY PIPELINE TRANSPORTATION
It is obvious that the working process of a ball mill or a rod mill is different from the pipeline transportation. In this study, the slurry pipeline transportation process is regarded as a special ball mill or rod mill grinding process. According to grinding theory, the overall equilibrium model for batch grinding can be expressed

Ball Mill Critical Speed
A Ball Mill Critical Speed (actually ball, rod, AG or SAG) is the speed at which the centrifugal forces equal gravitational forces at the mill shell’s inside surface and no balls will fall from its position onto the shell. The imagery below helps explain what goes on inside a mill as speed varies. Use our online formula. The mill speed is typically defined as the percent of the Theoretical

The ball velocity v0 is normalized wrt. the constant (maximal) velocity v1 of the agent. Let us now have a look at Figure 3. The ball moves with velocity v0 to the point where the agent can intercept it with velocity v1 . The angle β is the angle from the ball between the agent and the (approximated) interception point.
