Finished cement is produced by finely grinding together around 95% cement clinker with 5% gypsum (or anhydrite) which helps to retard.John Frank
Line granules and silica sand were ground for different periods to obtain a particle size that could completely pass the ∼70-μm sieve. Line had to be ground for an hour to get a median size (d50) of 11.57 μm, while silica sand had a median size (d50) of 12.28 μm after 2 h of grinding. By performing the grinding.

The 'Free silica' in question is quartz or other hard high-silica mineral. Since quartz is very hard it is much more difficult to grind than line and is therefore concentrated mostly in the coarse fractions of the kiln feed. The quartz in clays is already very fine <~5um) and normally poses no problem,.

People with silicosis are three times more likely to develop tuberculosis. Many mining processes, such as blasting, drilling, handling and transporting quartz-containing rock, can generate crystalline silica dust. Silica is found in sand, ores, rocks, flint, gravel, plaster, line, slate, bricks and other natural and man-made.

Lead and copper smelter workers are exposed to lead, arsenic, carbon monoxide, sulfur dioxide, and silica. [ILO Encyclo: Copper, Lead and Zinc Smelting and Refining] Copper smelting: After grinding the crushed ore, a slurry is formed to which flotation "assists" are added. The froth containing the copper is skimmed off,.
grinding technique and results are as given in table-1. The grain size of quartz and calcite in the line under above study is of around 2 – 150 µm and chemical composition 15.90 % (SiO2) and 43.26% (CaO ) respectively. From result of the study it has been observed that this technique has potentiality to reduce silica.
