Ball Mill Speed Formula Derivation Ball Mill Speed Formula Derivation Ball mill equation derivation jun 6 1993 lays the foundation for the derivation of a model if a large the mill speed nears 100 per cent of critical speed centrifug ing of the outer bonds equation implies that torque is zero for all j at for ball mill grinding control read
The basic parameters used in ball mill design power calculations rod mill or any tumbling mill sizing are material to be ground characteristics Bond Work Index bulk density specific density desired mill tonnage capacity DTPH operating solids or pulp density feed size as F80 and maximum ‘chunk size’ product size as P80 and maximum and finally the type of circuit openclosed
When the ball mill rotates at the critical speed the theoretical trajectory of the charge is such that it would fall outside the shell as centrifuging occur at this stage and the medium is carried around in a fixed position against the shell The formula to calculate critical speed is given below N c 42305 sqtDd N c critical speed of
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
