Operation and Elements of a Closed Circuit Ball Mill System. Cement ball mills typically have two grinding chambers. The first chamber is filled with larger diameter grinding media and lined with lifting liners. The first chamber coarsegrinds the feed material and prepares it for the second chamber. The second chamber is the fine grinding chamber.
be gained from media angle than a risk of breakage only. Table I illustrates or quantifies the media charge angle for different liner designs at different mill speed but with constant filling degree (30%). Indeed, as explained previously, at a mill stop, the measurement of ball charge filling degree could be undertaken and will provide the static
Calculation of the power draw of dry multicompartment 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.
