Some cement groups use a formula, such as Bond's, to calculate the maximum ball size required in a ball mill, based on the average size of the clinker feed. However, one drawback with this …
Some cement groups use a formula, such as Bond's, to calculate the maximum ball size required in a ball mill, based on the average size of the clinker feed. However, one drawback with this approach is that in some cases the formula will result in the prediction that 100mm balls be used to deal with large clinker particles.

ASTM C33 grading requirements permit a wide range of grading sizes, from #1 size (3–1/2 to 1–1/2 inch) to #8 size (3/8 in. to No. 8). It allows a selection of suitable coarse aggregate size based on job requirements. The maximum size of coarse aggregate used in concrete is based on economy and the type of structure.
ASTM C 125 defines the maximum aggregate size in one of two ways: Maximum size. The smallest sieve through which 100 percent of the aggregate sample particles pass. Superpave defines the maximum aggregate size as "one sieve larger than the nominal maximum size" (Roberts et al., 1996 [1]). Nominal maximum size. The largest sieve …
Cement is produced by a high-temperature (about 1500 °C) reaction in a rotary kiln of carefully proportioned and blended ratios of lime (CaO), silica (SiO 2), alumina (Al 2 O 3), and iron oxide (Fe 2 O 3).The production of cement is a chemical process requiring an accurate blend of the previously cited four key organic oxides and the …
