The optimum kiln feed residue depends on the mineralogy of the kiln feed. With a marl raw material of composition close to "cement rock" you might be OK with a 43% residue on a 90 micron sieve. But that would be very unusual. The more heterogenous the kiln feed and the higher the quartz content then the finer will the kiln feed need to be.

Brick clay mill residues used to produce samples were obtained from a local brick manufacturer in Melbourne, Australia. The particle size distribution of the raw mill residue is shown in Figure 15. Over 60% by weight (wt.%) of the mill residue particles are finer than 75 µm, and more than 30 wt.% of the particles are finer than 5 µm.

1. Introduction. In the cement industry, grinding is one of the most consuming energy stages in the production units. Around 65% of the total used electrical energy in a cement plant has to be utilized to grind raw materials, coal, and clinker [1,2].Through the process, many variables can affect the efficiency and productivity of this dry grinding procedure, such as the operating conditions of ...
