Circulating Load Calculation Formula - 911

21.02.2015· In practice, circulating loads between ball mills and classifiers are rarely less than 200 per cent and frequently exceed 700 per cent. It may appear strange at first sight that the circulating load between a mill and classifier producing, for example, 100 tons of finished product per day can be as much as 400 tons or more, but this will be made clear by Fig. 71.

How Cement Is Made

Cement is so fine that 1 pound of cement contains 150 billion grains. The cement is now ready for transport to ready-mix concrete companies to be used in a variety of construction projects. Although the dry process is the most modern and popular way to manufacture cement, some kilns in the United States use a wet process. The two processes are

then fed together into a mill where the rock is ground until more than 85% of the material is less than 90µm in diameter. Manufacture of Portland Cement The wet process : The clay is mixed to a paste in a washmill - a tank in which the clay is pulverised in the presence of water. Crushed lime is then added and the whole mixture further ground. Any material which is too coarse is extracted and

Re: Raw meal to clinker ratio - Page 2 of 5

For a kiln system where all dust streams are returned directly to the kiln, the final formula would be;-. A = (Tonnes coal fired * % ash of coal fired) / (tonnes of clinker produced) (NOTE: 'coal fired' above means raw coal expressed on an air-dried basis. This is because fine coal from the the coal mill usually has 4-5% of raw meal dust
