I then used a 2-roller homebrew mill and crushed the malts using four different gap settings. The gap settings were 1.25 mm, 1.0 mm, 0.75 mm and 0.50 mm. I used a feeler gauge to verify these settings in between each milling. I then performed a grain sieve test on the different malts and crushes, recording the results.

Empty the cylinder and weight the aggregates, accurate up to 1 gm. Transfer the whole of this weighted quantity to the test mould by filling it in three layers in the same manner as for cylindrical measure. The total depth of the sample is then about 10 cms and the surface a little below the top of mould.

The cement manufacturing process starts with the mining of limestone that is excavated from open cast mines. Then this limestone is crushed to -80 mm size and is loaded in longitudinal stockpiles. Limestone is taken out diagonally from these stockpiles for grinding in raw mill hoppers. As mentioned earlier coal is used as a fuel to heat the raw ...
