According to statistics, the energy consumption of grinding is about 10 times that of crushing [Morrell, 2004, 2008, and 2009]. Given the energy consumption distribution of ore crushing and grinding [Morrell, 2004, 2008, and 2009], the particle size of the crushed final product should be reduced as much as possible in the production process.

The calculation is based on the size-energy relationship e1,2=C.(1/x2n–1/x1n ), which for n = 0.5, x1 = ∞ and x2 =100, by definition gives e∞, 100 = Wi and consequently C=10Wi. In theory, for a given material the value found for Wi.should be constant regardless of the measured sizes x1 and x2 used to calculate the constant C by measuring ...

The metal Bond ball mill is 30.5 cm inside diameter and. 30.5 cm inside length, with rounded corners. It is smooth except for the door hole used for charging. The grinding charge consists of 285 iron or steel balls (43 @ 36.8 mm diameter, 67 @ 29.7 mm diameter, 10 @. 25.4 mm diameter, 71 @ 19.1 mm diameter, and 94 @.

This chemical reaction occurs at high temperature in a rotary kiln, grinding the cement clinker nodules to passing 90 microns in a dry circuit. fGrinding occurs at the beginning and the end of the cement making process. Approximately 1.5 tonnes of raw materials are required to produce 1 tonne of finished cement.

For coarse particle grinding in tumbling mills Eq. (1) is written as: (4) W a = K 1 M ia 4 x 2 f (x 2)-x 1 f (x 1) where. K 1 = 1.0 for all circuits that do not contain a recycle pebble crusher and 0.95 where circuits do have a pebble crusher.x 1 = P 80 in μm of the product of the last stage of crushing before grinding. x 2 = 750 μm.
