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.
Where G = total weight of ball charge (Kg) R = Inner mill radius (meters) L = useful mill length (meters) For R = 2.1 m. L = 14.25 m. The weight of ball charge G = 4620 (2.1) 2 14.25 = 290 tonne. 3.3. Mill charge with grinding media. The charge of grinding media for two-compartment ball mill can be calculated for dry grinding of …

Rubber lining, grate mill. Ball Mill Charge volume. The mill power is approximately directly proportional to the charge volume within the normal range. When calculating a mill 40 % charge volume is generally used. In pebble and ball mills quite often charge volumes close to 50 % are used. In a pebble mill the pebble consumption …
RETSCH Planetary Ball Mills are perfectly suited for processes like mechanical alloying or mechanosynthesis. For most reactions, the 1:-2 speed ratio of jar to sun wheel of the models PM 100 and PM 200 is fully adequate, as the ball charge produces enough impact energy. However, greater energy is required for some reactions.

Ball Charge. Ball mills for cement grinding usually operate with a filling degree between 25 and 35 %. The filling degree is defined as the volume of the grinding media (balls) as a percentage of the total mill volume. Since mill speed, liner shape and mill diameter are usually unchangeable parameters, the only adjustment in a mill can be made ...
There are two "inputs" to a ball mill circuit: the ore fed to the circuit and the power delivered by the grinding mill. A ball mill circuit has two "efficiencies": that of the ball mill grinding environment* and that of the classification system*. A ball mill circuit has two efficiencies because it has two main functions:
