Calculating Mill Drive RPMs: Is Your Mill Up to Speed? By Robert A. Sladky Vice President Tube Mill Engineering Many quot;Wquot; style mills that have the ability to shim up the bottom driven shafts in each section to maintain metal line after tooling is reworked, and are many times also equipped with a individual motor drive in each of the three sections as illustrated below.

at the kiln or mill shell at normal operating speed when the main drive is operating. Full load running torque required at the kiln or mill shell at inching operating speed. Typically this is set at 120% of main drive operating torque. The desired output speed at the shell. Usually this is targeted at RPM with a range of +50% / 10%
Function: A cement mill is a drive used to grind the hard, nodular clinker from the cement kiln into the fine grey powder that is cement. Most cement is currently ground in ball mills and also vertical roller mills which are more effective than ball mills. The speed is controlled between 150300 rpm to adjust the fineness of the cement

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 shells inside surface and no balls will fall from its position onto the shell. The imagery below helps explain what goes on inside a mill as speed varies. Use our online formula The mill speed is typically defined as the percent of the Theoretical

Figure The effect of mill speed on the power drawn by a rotating mill. The liner profile and the stickiness of the pulp in the mill can have a significant effect on the actual critical velocity. Mills usually operate in the range 65 82% of critical but values as high as 90% are sometimes used. A crucial parameter that defines the performance of a
The smaller grades are occasionally cylindrical (quot;pebsquot;) rather than spherical. There exists a speed of rotation (the quot;critical speedquot;) at which the contents of the mill would simply ride over the roof of the mill due to centrifugal action. The critical speed (rpm) is given by: n C = / d, where d is the internal diameter in metres. Ball mills are normally operated at around 75% of critical speed, so a mill with
VFDs offer much more flexibility in operating ranges like speed variation from 0 to 100 percent and a considerable reduction in maintenance costs Based on the above concept a control system is developed for the kiln mill drive used in Cement Industry using PLC, and which can be interfaced using SCADA.
