The best ball mills enable you to achieve the desired fineness quickly and efficiently, with minimum energy expenditure and low maintenance. With more than 4000 references worldwide, the FL ball mill is proven to do just that. What we offer. The ultimate ball mill – with flexibility built in. You can't optimise cement grinding with a ...
· Dry batch milling tests were performed in a laboratory scale ball mill measuring by cm. The mill specifiions are given in Table 1 . A constant ball load of 20% was maintained in all the tests with a ratio of for binary and for trinary ball mix.
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.
Cement mills . Double chamber ball mills for the cement industry come in various designs: For bearings, either slide or slide shoe bearings can be chosen. Possible drives include gear rim/pinion, lateral, or central drives. If the processing material is wet, cement mills .
· A ball mill also known as pebble mill or tumbling mill is a milling machine that consists of a hallow cylinder containing balls; mounted on a metallic frame such that it can be rotated along its longitudinal axis. The balls which could be of different diameter occupy 30 – 50 % of the mill volume and its size depends on the feed and mill size.
The L/D ratio of the ball mill was varied in four steps of,, and, and the ball charge filling ratio was varied in three steps of 15%, 20% and 25%. The experiments clearly indied that the optimal L/D ratio and the optimal ball charge filling ratio are different for each feed fineness.
Finish milling: Product can be designed to effectively grind clinker in dual or mono chamber cement mills. Optimized ball charges can ensure proper grinding efficiency to fully utilize the mill power to produce the required Blaine. Raw milling: Cast High Chrome grinding media offer a longer lasting ball for dry or wet raw milling of the kiln ...

Ball mills (Fig ) are coming in cement plant areas of raw grinding, coal grinding and cement grinding which in turn as raw mill, coal mill and cement mill. Ball mills are horizontal tube mills having single or two compartments for grinding, Balls as grinding media and driven by side or central drive.
Ball mills with high efficiency separators have been used for cement grinding in cement plants all these years. Ball mill is a cylinder rotating at about 7080% of critical speed on two trunnions in white metal bearings or slide shoe bearings for large capacity mills.
