## particle size distribution in cement mill

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)....
