Jet mill grinding produces irregular cementitious particles with an average particle size of approximately 4 μm or less with a narrowed size distribution range XRD indicated that jet mill grinding is a physical process only and results in no discernible phase transformations
serious challenge to obtain a good performance of a vertical roller mill in cement grinding Today, however, the OK mill has become an excellent example of a mill design that has overcome the difficult grinding conditions associated with finish grinding of cement clinker and related products The OK mill was developed by Onoda Cement Co, Onoda Engineering and Consulting Co and Kobe Steel in
Due to limitation of the mill’s rotational speed, the smallest ball size is usually restricted to about 15 mm Cement grinding using stirred mills (Pilevneli and Azizli, 1999) indicates that using smaller media (5–8 mm range) improves grinding energy efficiency up to 50% using stirred mills For specialized types of cement, which are finer than Portland, this figure would be even higher
