# A Ball Mill Critical Speed

### Technical Notes 8 Grinding Ring Mineral Tech

The critical speed of the mill, c, is defined as the speed at which a single ball will just remain against the wall for a full cycle.At the top of the cycle 0 and fc fg 8.5 mp 2 cdm 2 mpg 8.6 c 2g dm 12 8.7 the critical speed is usually expressed in terms of the number of revolutions per second nc c 2 1 2 2g dm 12 29.8112.

### Optimum Revolution And Rotational Directions And

Based on this result, an optimum rotation-to-revolution speed ratio and rotational direction of the pot to the revolution disk were investigated by the simulation work.A significant large specific impact energy is obtained when the mill pot is rotated at around the critical speed ratio in the counter direction to the disk revolution at around.

### Ball Mills Mine Engineerm

The point where the mill becomes a centrifuge is called the critical speed, and ball mills usually operate at 65 to 75 of the critical speed.Ball mills are generally used to grind material 14 inch and finer, down to the particle size of 20 to 75 microns.To achieve a reasonable efficiency with ball mills, they must be operated in a closed.
