    US5233852A - Mill actuator reference adaptation for speed

    A method providing a rolling mill with compensation for changes occurring in rolling parameters that result from changes occurring in mill speed. The rolling parameters are under control of actuators that are connected to receive control reference voltages from electrical controllers. The method includes the step of generating a compensation function that describes the actuator movement

    Variables in Ball Mill Operation | Paul O. Abbe®

    The formula for critical speed is CS = 1/2π √ (g/ (R-r) where g is the gravitational constant, R is the inside diameter of the mill and r is the diameter of one piece of media. This reduced to CS = 265.45/√ (R-r). Dry mills typically operate in the range of 50%-70% of CS and most often between 60%-65% of CS
