1 Calculation of ball mill capacity. The production capacity of the ball mill is determined by the amount of material required to be ground, and it must have a certain margin when designing and selecting. There are many factors affecting the production capacity of the ball mill, in addition to the nature of the material (grain size, hardness, density, temperature and humidity), the degree of

Note that the preload torque fluctuates due to manufacturing tolerances and lead variation, so manufacturers will either provide a range of allowable values (for example, 0.04 to 0.17 Nm), or they will indicate an allowable percentage variation from a nominal preload torque value (for example, 0.10 Nm, ±40 %).

The starting torque of a rolling bearing is defined as the frictional moment that must be overcome by the bearing to start rotating, at an ambient temperature of 20 to 30 °C (70 to 85 °F). Therefore, only the sliding frictional moment and the frictional moment of seals, if applied, are taken into consideration. M start = M sl + M seal.

The formula: Torque=5252*HP/RPM is very useful. As we can see, if HP is constant, Torque will decrease as the speed increases. This is very important to note in test stand applications where a large electric motor is used. Many test stands run at 20,000 + RPM where a large motor is producing a seemingly unusual low amount of torque.
