The fill-up calculation determine how much cement slurry is needed to fill the annulus or open hole to a certain height. From this calculation and the slurry calculations, the correct amount of cement blend and water can be brought to location. Unless a caliper survey is run to determine accurate hole size, always add an excess cement volume

In Grinding, selecting (calculate) the correct or optimum ball size that allows for the best and optimum/ideal or target grind size to be achieved by your ball mill is an important thing for a Mineral Processing Engineer AKA Metallurgist to do. 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.

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.

8-3 Centrifugal force outward Fc mp& 2 Dm 2 (8.1) & is the angular velocity, mp is the mass of any particle (media or charge) in the mill and Dm is the diameter of the mill inside the liners. Gravitational force Fg mpg (8.2) The particle will remain against the wall if these two forces are in balance ie.
