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 …
The size of the mill is directly proportional to its capacity and the size of the particles it can produce. - Motor Power: The motor power of a ball mill is an important factor in determining its grinding capacity. Ball mills can be equipped with motors ranging from 10 kW to 500 kW or more, depending on the size and desired output of the mill ...
The autogenous mill will grind the material to the extent that the content of the particles with particle size <0.074 mm accounts for 20–50% of total quantity of product, and crushing ratio is 4000–5000, which is over 10 times that of ball mill and rod mill.
Critical speed carries significant importance in the continuous operation of a ball mill. It is the point at which the centrifugal force acting on the grinding media becomes equal to the force of gravity, thus ensuring that the grinding media remains in constant motion within the mill. ... Conical ball mills are particularly advantageous in ...
