what is the optimal rotation speed for a ball mill
Mill Circuit Pump Manual Weir Minerals. or ball mills There are others which use just the force of the ore falling on itself to break it down into a smaller size,critical speed The mill critical speed is the rotational speed at which the centrifugal force forces the mate rial to the interior mill walls and impedes the,feed of ore to the mill, ensuring optimal retention time.
Factors Affecting Ball Mill Grinding Efficiency
· The following are factors that have been investigated and applied in conventional ball milling in order to maximize grinding efficiency: a) Mill Geometry and Speed – Bond (1954) observed grinding efficiency to be a function of ball mill diameter, and established empirical relationships for recommended media size and mill speed that take this factor into account.
What Is The Optimum Rotation Speed For A Ball Mill
Speed of rotation of mill – At low speeds the balls simply roll over one another and little grinding is obtained while at very high speeds the balls are simply carried along the walls of the shells and little or no grinding takes place so for an effective grinding the ball mill should be operated at a speed that is optimum speed equal to .
Optimum revolution and rotational directions and their ...
Based on this result, an optimum rotationtorevolution 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 the critical speed ratio.

What it is the optimun speed for a ball mill ...
· Calculation of optimum speed depends on knowing the media diameter and jar also. For instance, if your jar had in inside diameter of 90 mm and your milling media was mm diameter lead balls, the optimum rotation would be 98 RPM. Optimum RPM= .65 x Critical speed (cascading action of the media stops)
