- Ball top size (bond formula): calculation of the top size grinding media (balls or cylpebs):-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:
Jun 19, 2015 We can calculate the steel charge volume of a ball or rod mill and express it as the % of the volume within the liners that is filled with grinding media. While the mill is stopped, the charge volume can be gotten by measuring the diameter inside the liners and the distance from the top of the charge to the top of the mill.
Aug 02, 2013 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.

Dec 08, 2009 Re: how to estimate the wear rate for Ball mill. Hey; Ball wear can be measured by weighing an entire charge before and after grinding a known tonnage of materials. With new balls sample of given size can be weighed before and after grinding a given tonnage and, assuming uniform wear per unit of ball surface, the total charge wear can be estimated.

Mar 01, 2006 The initial charge of cement clinker was dried at 105 C and sieved between 2.8 and 0.09 mm, using a √2 sieve series to obtain different cement clinker fractions. Cement clinker loads used in the experiments were either crude feed material (− 2.8 mm) or mono-sized fractions (2–1.4 or 1–0.71 mm), or mixtures of the crude material with ...
The ball mill is one kind of new high efficient grinding machine. This mill is mainly used for coarse powder and small size of sand producing. The ball mill is widely used in metallurgy, mining, chemical, cement, construction, industrial and mining industries etc. Ball Mill is crucial equipment for grinding after materials are crushed.
Aug 09, 2016 Over time the charge (steel grinding balls) wear out, so when they reach a certain size they fall through a sieve and then are replaced. The cement grinding process is highly energy intensive. The largest mill at Golden Bay Cement is some 11 m in length, weighs over 230 T, is driven by a 2100 kW motor and can produce over 60 T hr-1.
