rotation speed for ball mill

2.2 Rotation Speed Calculation of Ball Mill \ Critical Speed_ When the ball mill cylinder is rotated, there is no relative slip between the grinding medium and the cylinder wall, and it just starts to run in a state of rotation with the cylinder of the mill. This instantaneous speed of the mill is as follows:

    rotational speed for ball mill

    Critical rotation speed of dry ball-mill was studied by experiments and by numerical simulation using Discrete Element Method (DEM). The results carried out by both methods showed good agreement. It has been commonly accepted that the critical rotation speed is a function of a ball radius and a jar diameter

    The actual mills fluctuated around 76%. In the current production, when the rotation speed of the ball mill is less than 76% of the critical rotation speed, it is called low-speed grinding; when the rotation speed is higher than the critical rotation speed of 88%, it is called high-speed grinding; Speed grinding

    3. If the rotation speed of the ball mill exceeds a certain limit (the rotation speed is very high), the steel ball rotates with the barrel without falling, and is in a centrifugal operation state. At this time, the steel ball has no impact effect, and the grinding effect is very small to stop the grinding effect

    e. Rotation speed of the cylinder. Several types of ball mills exist. They differ to an extent in their operating principle. They also differ in their maximum capacity of the milling vessel, ranging from 0.010 liters for planetary ball mills, mixer mills, or vibration ball mills to several 100 liters for horizontal rolling ball mills

    The high energy of these mills is derived from the very high rotation speeds that are achievable. For example, Salimon et al. used their planetary ball mill at a rotation speed of 1235 rpm corresponding to the mill energy intensity of 50 W/g. It has been reported that some of these mills can be used at rotation speeds greater than 2000 rpm

With the motor i will use a 40 mm pulley , because i have a 50 mm driven pulley, in one of my two shafts. In the other side of my shafts there are two 40 mm
