3.7 The fineness and particle size distribution of

3.7 The fineness and particle size distribution of Portland cement. The final step in the production of cement is to grind the clinker pellets (and added gypsum) into a fine powder. The resulting individual cement particles have a variety of angular shapes, and a wide range of sizes (see Figure 3-7 below).

However, particle size distribution is again a problem, and roll presses are now increasingly popular as a "pre-grind" process, with the cement finished in a single chamber ball mill. This gives good cement performance, and reduces energy consumption by 20-40% compared with a standard ball mill system. Capacity of cement mills

Cement grinding Vertical roller mills versus ball mills

High circulation factors invariably lead to steep particle size distribution curves, if the separation process is efficient. It has therefore been necessary to adapt special measures to reduce the inclination of the particle size distribution curve, in order to get a cement quality that is similar to the quality of cement ground in a ball mill.

Improving particle size distribution in cement production

Assessing cement fineness. In the past, cement producers gauged cement fineness (i.e., cement particle size) by evaluating the specific surface area (SSA) or Blaine fineness and the sieve residue at various sizes. However, many producers now use particle size analysis techniques to assess fineness and help monitor the efficiency of the mill.
