Finish grinding of clinker and other cement ingredients reduces 25 mm clinker balls to particle sizes optimally ranging from 3 to 30 microns. The European Cement Research Academy (ECRA) estimates that up to 70% of the power consumed in cement production is for material size reduction.

Digital Grid Lab. In our Digital Grid Lab we can model distribution grids in the power range up to 800 kVA for low voltage with our new power-hardware-in-the-loop (PHIL) simulator. The grid state and the digital communication system are simulated in the HIL system. This allows us to evaluate operational decisions and system changes beforehand.

In the manufacture of Portland Cement, clinker is the solid material produced at the cement kiln stage that has sintered into lumps or nodules, typically of diameter 3-25 mm. Clinker, if stored in dry conditions, can be kept for several months without appreciable loss of quality. Because of this, and because it can easily be handled by ordinary ...

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. Hard burning may be necessary when the fuel burning is not optimal.
