# How to achieve 8 charge of grinding media at 45microns into ball mill at cement factory

Although the tube ball mill was invented 120 years ago its grinding media charge ... of the fine grinding chamber of a ball mill for finish grinding cement that has ... into account when designing and calculating the performance of a ball mill

• Ball Mill Optimization - SlideShare

The nearby cement plant operates with 20 mins retention time for clinker grinding in the ball mill & 70 Ton hold up. Power consumption = kW = 7.5 x Gw x D0.5 = 7.5 x 163 x 3.80.5 = 2383 kW. (Check its correctness) (13) Grinding energy = 30-35 kWh / Ton cement . Here, Gw = ball charge, ( Ton ); and D = Effective mill diameter, ( m )

Grinding Power efficiencies are achieved by 100% filling of charge and smaller steel media (balls) used for fine grinding. Typically, stirred media mills use 25mm make-up balls, where conventional ball mills are using much larger grinding media. The popularity of stirred media mills has risen in recent times

Nov 18, 2008 Nov 18, 2008 2. Basic principle Ball mill is generally used to grind material 1/4 inch and finer, down to the particle size of 20 to 75 microns. To achieve a reasonable efficiency with ball mills, they must be operated in a closed system. There is a specific operating speed for most efficient grinding

• Cement milling Question 5 - Page 3 of 26

Re: Cement milling. The normal method to charge balls into the ball mill is to position the doors at the top of the mill and remove them. Then to pour the barrels of grinding balls into the mill using an overhead crane. The exact grading of media required is identified by performing an axial test taking samples along the axis of mill
