Coal mill is the main equipment in the pulverized coal preparation process.Because calcining top-grade cement clinker requires a stable supply of coal powder as the fuel of cement kiln, and more than 85% of pulverized coal should be finer than 200 mesh, water content less than 2%, and calorific value more than 6000Kcal/kg, therefore the …
Solid fuels with lower volatile content must be pulverized to a higher fineness for good combustion and flame shaping. As a rule, a decrease of 1% in volatiles requires an increase of 1% in the percentage of material passing a 74 µm (200-mesh) sieve.
Ensuring a sufficiently ground kiln feed (between 10% to 20% on the 200 mesh) will not only enhance the reactivity in the kiln and reduce the required heat input, but also help to avoid large...

Exshaw FM2 successfully uses this idea to make the mill sweep dust fine enough for finish cement. However the box is extremely large to accomplish this. As a rule of thumb for cement mills, the air velocity around the discharge trunnion and hood must be less than 4 m/s. In Exshaw's dropout box they strive for about 2 m/s.
A cement separator can effectively separate the clinker and fineness adjustment materials in the cement mill,so as to control the quality and fineness of the cement. ... 110-200. 55. 95-130.

Even if the cement is not low-alkali cement (below 0.60%), the amount is important for three reasons: Air-entraining agents generally produce more air as the alkali content goes up. Where the alkali occurs in the cement can affect this, but to get a first approximation, we need to track the equivalent alkali content.
