"The three authors from Metcom Technologies are highly regarded contributors to the field of comminution efficiency, last year publishing (along with Jim Finch) a paper on ball mill classification system optimisation that was Highly Commended by the CEEC Medal judges," CEEC said.
Ball Mill Charge Grinding Classification Circuits. Ball Mill Charge 1 reply The ball charge and ore charge volume is a variable subject to what is the target for that operation The type of mill also is a factor as if it is an overflow mill subject to the diameter of the discharge port is usually up to about 4045 If it is a grate discharge you will have more flexibility of the total charge
The ball mill is a tumbling mill that uses steel balls as the grinding media. The length of the cylindrical shell is usually 1– times the shell diameter (Figure ).The feed can be dry, with less than 3% moisture to minimize ball coating, or slurry containing 20–40% water by weight.
When faced with materials that can be difficult to grind or that require a narrower particle distribution curve, the unique capabilities of the air classifying mill are often necessary. Large access doors on the air classifying mills allow for quick inspection or cleaning of the main rotor and classifier rotor.
ball mill can be reorganised as [7] and [8], where B''Wio and A''Wio are the corrected operating work indices and WAG/SAG, WBM are the respective power draw of AG/SAG and ball mills. Note that the ball mill operating work index is applied only on the portion that needs the additional grinding (Q2), which renders to the AG/SAG mill the
Union Process is the source for the most uptodate information on grinding balls and other media. Click the link above to view a detailed sheet, outlining factors to consider when selecting grinding media, along with specifications on the most common types of media.
Closed Circuit Ball Mill System. Clinker, Gypsum and other desired additives are fed to the ball mill in specific proportions based on the quality requirement. Feed material is ground in the ball mill, discharged and fed to a classifier with the help of a bucket elevator for classification of the ground cement into two streams – coarse and fines.

The ore goes through comminution using rod mills, ball mills, or autogenous mills. Steam is consistently used to condition the ground ore, along with soda ash fluosilicate, and usually Tail Oil C30. This is done to coat the various types of rare earth metals with either flocculent, collectors, or modifiers for easier separation in the next step.
Cylindrical Ball Mills. The only cylindrical ball mills in common use are those of the grate discharge type, the most important being the Marcy and the AllisChalmers mills. Fig. 10 illustrates the construction of the Marcy Ball Mill. The cylindrical shell and the feed and discharge heads are made of cast semisteel.

The high unit capacity SAG mill/ball mill circuit is dominant today and has contributed toward substantial savings in capital and operating costs, which has in turn made many lowgrade, hightonnage operations such as copper and gold ores feasible. Future circuits may see increasing use of high pressure grinding rolls (Rosas et al., 2012).
Our EXAMPLE Grinding and Classification Circuit is designed to grind 500 tonnes of ore per day, operating 24 hours per day, with an availability of 95%. This circuit will grind 5/8″ material from the Crushing Plant, classify the slurry in one of two cyclones, and pass 70% of the minus 200 mesh material to the mill feed Thickener Circuit at a rate of 22 mtph.

Ball Mill for Sale. APPROXIMATE CAPACITIES. All ball mills operate on the same principles. One of these principle is that the total weight of the charge in the millthe sum of the weight of the grinding media, the weight of the material to be ground, and any water in the mill—is a function of the percentage of the volume of the mill it occupies.
Besides their efficiency, at the time we are speaking, I do not know of any other software (3DDEM modeling) able to address and simulate (and later on optimize) an industrial or even a pilote Mill equipped with classifying liners. I mean able to predict the long term classification of ball (and rocks) inside the mill.
