A ball mill is a type of grinder used to grind and blend materials for use in ... The grinding works on the principle of critical speed. Critical speed can be understood as that speed after which the steel balls (which are responsible for the grinding of particles) start rotating along the direction of the cylindrical device; thus causing no ...
Ball Mill Critical Speed Mineral Processing Metallurgy 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.
However, the maximum in power occurs at different fractions of critical speed from one mill to another, depending on the mill diameter, the type of lifters, the ratio of ball to mill diameter, and the ball and powder filling conditions. The maximum is usually found in the range of 70 to 85%' of critical speed.
