A mill's ball charge may vary, depending on the qualities and other characteristics of the material being used. Figure 1 Electricity consumption structure in the mills being studied, 2009. Figure 2. External view of the type of mill being studied. High quality cement grinding in this type of mill mainly depends on the mill load ball,

Key words: power draw, cement, dry grinding, ball mill input to the motor when the mill is empty, charge-motion power is the power. Get Price Impact Load Behavior between Different Charge and Lifter in

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 coarse-grinds the feed material and prepares it for the second chamber. The second chamber is the fine grinding chamber.

Calculate and Select Ball Mill Ball Size for Optimum Grinding. Often, the ball used in ball mills is oversize “just in case”. Well, this safety factor can cost you much in recovery and/or mill liner wear and tear.

-Modification of the Ball Charge: This calculator analyses the granulometry of the material inside the mill and proposes a modification of the ball charge in order to improve the mill efficiency: - Ball charges composition: These calculators give the gradation of the ball charge in function of predefined conditions:

Also with low ball charge slurry pool will reduce grinding efficiency. Beside lower ball charge will increase P80 of ball mill because of less number of impacts but mean residence time will increase by lower ball charge because of more volume to occupy. I think at last in this situation, power consumption will increase.

Request for feedback for a Two Chamber Cement Mill Ball Charge and Longitudinal Sieve Analysis I am looking to get feedback for the following cement mill for a white cement plant. The first compartment has lifting liners and the second compartment has lifting at the beginning followed by classifying liner.

cement mill grinding media charge calculation. calculate the charging in cement mill pdf. 2 State of the art-L/D ratio and ball charge filling ratio One can calculate W m from the power draw of a mill measured at shaft For cement clinker a can be set to ball charge filling ratio 10%, relative mill Published in International .

the mill is used primarily to lift the load medium and charge . Additional power is required to keep the mill rotating. 8.1.3 Power drawn by ball, semi-autogenous and autogenous mills A simplified picture of the mill load is shown in Figure 8.3 Ad this can be used to establish the essential features of a model for mill power.

Ball Mills. Large balls are used at the inlet, to crush clinker nodules which can be over 25 mm in diameter . Ball diameter here is in the range 60 80 mm. In a two-chamber mill, the media in the second chamber are typically in the range 15 40 mm, although media down to 5 mm are sometimes encountered.

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.

Re: Request for feedback for a Two Chamber Cement Mill Ball Charge and Longitudinal Sieve Analysis. As per your given mill details. mill output assumed to be 45 tons / hr for more details you can contact me at vikprocem gmail.com It is not so easy to understand the cement plant without being present at site. But, still according to my calculations- - The size of your first chamber grinding

The Motion of the Ball Charge The input energy in ball milling is that applied by the drive to impart motion to the mill charge.

Equation 1 is multiplied by the factor of 1.08. A multi-compartment ball mill consists of two or more grate discharge ball mills in series. The same equation is used to calculate the power that each ball mill compartment should draw. The total power is the sum of the power calculated for each of the separate compartments.
