In coal milling for power stations, a 'closed-loop' process is used in which the rejects from the classifier are returned to the mill for regrinding. In VSMs, the re-circulation loop is within the mill, but some mill types would have an external loop. In fact, there are a number of re-circulation loops within a mill system.
a=Dynamic angle of repose of grinding charges, usually 43° for dry grinding slow speed ball mill, 51° for normal ball mill speeds. *The theoretical exponent is 2.5, but actual results indicate that 2.6 is more nearly correct. Fig. 1—Table of 2.6 Power of Frequently Used Mill Diameters.
Calculation of the power draw of dry multi-compartment ball mills 225 The mill load that is the volume of charge in the mill is the principal determinant of power draw. Estimation of the ball load that is mixed with the cement charge is difficult and can be highly erroneous. So direct measurement must be taken for calculation of mill load.

experimental data for 20 percent mill speed and Figure 5.10 compares the angle of repose at various speeds for 20 percent mill filling. It was found that angles of repose of the charge increased with mill speeds for the studied mill speeds. It was further established that cylpebs have higher dynamic angles of repose compared to the other
Specialized Cement Mill. In the cement production line, we use cement crusher for cement crushing process, then we need cement mill for fine grinding stage. As a kind of cement grinding machine, Cement mill is the equipment used for grinding the hard, nodular clinker from the cement kiln into the fine grey powder that is cement.
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. Process: Raw materials are fed to the mill in right proportion with the help of weighfeeders.

Ball mills are normally operated at around 75% of critical speed, so a mill with diameter 5 metres will turn at around 14 rpm. The mill is usually divided into at least two chambers, allowing the use of different sizes of grinding media. Large balls are used at the inlet, to crush clinker nodules (which can be over 25 mm in diameter).
