Everything you need to know about clinker/cement Grinding

1) alite size, as before. 2) C2S content, as before. 3) grinding aid. Cost 0.6-1.2 €/t, usage 150-400 g/t. As the cement particle gets smaller the pores disappear and no longer become a factor. Increasing the amount of grinding aid will make the cement easier to grind. Hard burning = hard grinding.

Understanding Pulverized Coal Injection in Blast Furnace

The coal is then fed into the mill where it is pulverized and dried. Coal of the required size is transported out of the mill by the hot gas stream, collected in a bag filter and conveyed to the storage bins. Grinding and transport are carried out under an inert atmosphere to minimize the risk of ignition of the dry coal particles.

Energy consumption of two-stage fine grinding of Douglas-fir wood

The hammer mill grinding circuit ran near the total rated power of 42 kW for the wood chip grinding. The SEC was 0.250 kWh/OD kg wood. The net SEC, calculated by subtracting the energy input of idle run from the SEC, was 0.186 kWh/OD kg, or 74% of the SEC. The ratio of the net SEC and SEC is an important parameter for evaluating …
