Learn MoreSep 10, 2020 · The operating-mode selection of the ball mill (sometimes called «the operating-mode of grinding media») depends on three main parameters: The relative frequency speed of drum is equal to the ratio between the actual speed to critical speed of mill drum. Proxy critical rotation frequency of rotation of the drum is equivalent to a speed at which the inertia of balls rotational motion equals
Learn MoreThe critical speed of the ball mill is the speed at which the centrifugal force is equal to the gravity on the inner surface of the mill so that no ball falls from its position onto the mill shell. Ball mill machines usually operates at 65-75% of critical speed
Learn MoreI've never constructed a ball mill, but I can tell you that the rotation speed is Critical. The speed (RPM) depends on the size of the jar. I've never seen a ball mill that operates with a rheostat. The correct speed is achieved through speed reduction via a gearbox and/or pulleys. How far apart the roller shafts are depends on the size of the jar
Learn MoreOperating speed must be kept less than the critical speed; Speed at which the outermost ball released from the mill wall depends on the interaction of gravitational and centrifugal forces; Critical speed can be determined by; nc = 1/2╥Ög/R-r; nc = critical speed, revolution/sec g= acceleration due to gravity, 9.8 m/s2 R- radius of the mill
