Abstract: The paper presents development and validation of coal mill model (including the action of classifier) to be used for improved coal mill control. The model is developed by using the mass and heat balance equations of the coal mill. Genetic Algorithm is used to estimate the unknown parameters that are used in the model validation.
For skim milk, r1 =, A = 1032 kg m3, cream r2 = m, = 915 kg m3 Answer : 17 cm. 2. A dilute slurry containes small solid food particles having a diameter of 5 x 10 2 mm, which are to be removed by centrifuging. The particle density is 1050 kg/m 3 and the solution density is 1000 kg/m3.
In the fourth test, the balls were of fin. diameter; 2500 g of balls (50% of mill volume) and 130 g of coal were charged to the mill. The breakage mechanism in this test differed drastically from 77breakage. The attempts to fit the observed product distributions, after 2j, 5 and 7jmin grinding, shown in table 12 c, have failed completely.
