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.

Also the grinding pressure has an influence on the particle size distribution. The higher the grinding pressure, the higher the energy input per pass between roller and table, and the lower the circulation factor, and consequently the lower the inclination of the particle size distribution curve.

Ball Mills can be supplied with either ceramic or rubber linings for wet or dry grinding, for continuous or batch type operation, in sizes from 15″ x 21″ to 8′ x 12′. High density ceramic linings of uniform hardness male possible thinner linings and greater and more effective grinding volume.

Cement Chapter 3 Mill (Grinding) Particle Size. cement properties since the proportion of coarse particles (residue) can vary significantly for a constant SSA. The understanding of the influence of cement fineness on cement properties can only be more fully understood when one has a knowledge of the complete particle size distribution (PSD).

To evaluate the effect of the classifications of particle-size distribution of cement, the mix proportion was newly required. Nine mix proportions by the amount of different sizes of cement were classified based on the accumulated remains denoted as R at 10 m (R10), 20 m (R20), 40 m (R40), and 80 m (R80) using an Alpine air jet sieve shaker, as shown in Table 5, and the …

In this article the effect of grinding media size distribution and feed material particle size distribution (PSD) on the product fineness requirements were investigated. A model free approach called the Attainable Region method was then applied in order to optimize the product size fineness in terms of the feed size and ball mix.

To achieve the best result, you need optimal particle size distribution and dehydration of the gypsum within the cement. And for that, the precise operational controls of the VRM are a clear advantage over other mill types, enabling you to optimize the system's temperature profile, mill airflow, separator speed and grinding pressure for optimum efficiency and productivity.
