As a general rule, there should be less than 25% of clinker that is below 1mm in size. Coarse clinker is more of an issue for ball mills. 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.
— The clinker to cement ratios given by Atmaca and Yumrutaş, 2014, Kapur et al., 2009, and Low (2005) are higher than the clinker to cement ratio in this study. These higher values indicate that more resources are required to produce a ton of cement. The waste gas, at a temperature of 353.15 K, was not recycled for other purposes in any of …
The cement roller press is a type of material-crushing machine which is often used in cement plants. It usually works together with a ball mill to form a pre-grinding or final-grinding system for the grinding of raw materials, coal, and clinker.. Compared with the traditional tube mill and ball mill, the roller press has lower energy consumption and …
The clinker-to-cement ratio in the EU was of 77.3% in 2021 (GCCA, Getting the numbers right database), down 0.6% as compared to 2020. Some countries are indeed performing below this level, but it is important to keep in mind the following points when making international comparisons:

— Large clinker nodules (Figure 2) are difficult to cool, transport and grind into cement. Clinker should ideally have a smaller average nodule size and a narrow nodule size range. More uniformly sized clinker is more evenly distributed into the cooler and has more consistent bed porosity, which enables more stable cooler and kiln operation.
