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.

Re: degree of kiln filling. Degree of kiln filling means volumetric filling percentage of kiln charge inside the kiln (i.e. charge volume divided by kiln volume).To get the heat transferred into the ineterior of the charge it is an advantage to get a low degree of filling in the kiln.For this reason it is often an advantage to use a high kiln speed, despite the reduce residence time of the ...

A cement mill (or finish mill in North American usage) is the equipment 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.

A transparent mill (552 × 180 mm), made of Perspex material and filled with 10 mm balls, was used for the tests. Ball filling and mill fractional speed were kept constant respectively at 20% and 60% while slurry filling was varied from 0% to 300%. Using a high speed video camera, the …
