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.
The ball mill is a key piece of equipment for grinding crushed materials, and it is widely used in production lines for powders such as cement, sili es, refractory material, fertilizer, glass ceramics, etc., as well as for ore dressing of ferrous and non-ferrous metals. The ball mill can grind ores and other materials, wet or dry.
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 classifi ion of the ground cement into two streams – coarse and fines.
Cement grinding. The clinker from the pyro-processing area is ground in ball mills or roll press Ball mill combination or vertical roller mills to form cement. Commonly used separators are in closed circuit grinding are: O –sepa, Sepol and Sepax separators to achieve a finish cement fineness of 3000 – 4000 Blaine surface cm2/gm .
The basic parameters used in ball mill design power calculations , rod mill or any tumbling mill sizing are; material to be ground, characteristics, Bond Work Index, bulk density, specific density, desired mill tonnage capacity DTPH, operating % solids or pulp density, feed size as F80 and maximum ‘chunk size’, product size as P80 and maximum and finally the type of circuit open/closed ...
Ball mills and vertical roller mills are used for many grinding appli ions in cement production: meal grinding, coal and pet coke, and finish cement grinding. Improving the competences of the team plays a key role in the optimal utilisation of the grinding installation in your cement plant. The operators and process engineers must be able ...

The circuit consists of a two compartment ball mill and a dynamic air classifier. There is a slotted diaphragm inside the ball mill that separates the two chambers from each other. The particles coarser than the size of the slots 10 mm stay in the first chamber while the finer particles pass the second chamber for further size reduction.
