2) Ball milling – a ball mill with a diameter of 2.44 meters, inside new liners, grinding wet in open circuit. When the grinding conditions differ from these specified conditions, efficiency factors (Rowland and Kjos, 1978) have to be used in conjunction with equation 1.

The same seats and drivers used in cement mills are used precisely for this mill. ... a diaphragm or grate discharge mill and a center-periphery discharge mill. ... The open and closed circuit ball in Figure 1 is shown as simple as possible. Fig. 1.

It is generally accepted that practical mill power (PM ) is a function of mill capacity and diameter, i.e.,P M = Mill Constant * (Mill Diameter ) n where n = 0.3 to 0.5. It is evident that mill power is a function of the height at which the media is lifted and the density of the media, i.e., PM = K Ï b LD 2.5 where k is a proportionality constant.

A ball mill diaphragm for the modern cement plant. An inefficient ball mill is a costly weight on a range of cement plant KPIs – from the bottom line to the environmental footprint and the quality of product. Getting the ball mill right is therefore vital to ensuring a plant is as productive and profitable as possible, in the most sustainable ...

In open circuit, the material is fed into the mill at a rate calculated to produce the correct finished product in one pass through the mill. This circuit has been popular in the cement and chemical industries, although the present trend is toward closed circuit installations.

A diaphragm (see Figure 1) separates the two compartments and allows only particles below a certain size to pass to the second compartment. Ground material exits the mill through the discharge grate which prevents grinding balls from leaving the mill. A proportion of material, mostly fines, is "air-swept" out of the mill.

The cement mill certificate includes three performance tests that merit close attention: false set, Vicat setting time and strength. False set. False set is the tendency for cement mixtures to stiffen early, typically due to the sulfate in the cement reacting with the water to form gypsum crystals over the first few minutes of mixing.
