portion of very fine particles and a broad particle distribution. Expressed as inclination of the particle size distribution according RRSB, cements from ball mills generally have a rather low slope [n']. In a VRM the grinding takes place by pressure and shear force. The clinker passes within seconds between roller and table.

Product Quality When VRM was first mooted as an alternative in cement production, one of its seeming challenges was its particle size distribution (PSD). Due to their high separation efficiency and its high circulation factor, VRM tends to produce cement with a steep PSD curve unlike those generated by ball mills.

Narrow particle size distributions. Fracturing of the material is accom- plished only by the induced stress/shear action of the roll surface on the prod- uct. There is no attrition, high speed impact, or internal screening. For many materials, this results in significant narrowing of the particle size distribution.

Particle size distribution is a measurement that defines the number of particles present according to their size. As you can see in Figure 1, spherical particles are described using the particle's diameter as a single number, as all the dimensions are identical. However, not all particles in a sample of powder are perfectly spherical.
