Effect of Different Mixtures on Specific Surface …
In roller mill grinding cement, the amount of limestone mixed material is positively correlated with the specific surface area of cement. For every 1% increase of limestone, the specific surface area of the finished product increases by 2.52~2.75m2/kg. For every 1% increase in fly ash, the specific surface area of the product will increase to varying degrees. When using volcanic ash as a mixed material, for …
Cement mill - Wikipedia
A 10 MW cement mill, output 270 tonnes per hour 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.

CASE STUDY – FINISH MILLING – The Cement …
* SSA is the specific surface area (m 2 /kg) of the finished cement (final product). CLOSED CIRCUIT MILL ‑ ANSWER. i) Lower mill exit surface area means lower fineness in the mill itself and so less tendency for agglomeration, coating, over grinding, cushioning etc. Therefore, grinding is more efficient and a higher rate of surface production is apparent. Product SSA = 350 m 2 /kg; For open – circuit …
Cement Milling - Understanding Cement
Cement milling is usually carried out using ball mills with two or more separate chambers containing different sizes of grinding media (steel balls). Grinding clinker requires a lot of energy. How easy a particular clinker is to grind ("grindability") is not always easy to predict, but large clusters of belite due to coarse silica in the feed are difficult to grind.
