- Abstract
This study deals with ultrafine dry grinding of Egyptian calcium carbonate particles using a micronizer called "Planetary Mill". As the size decreases during the process, the particles are strongly subjected to attractive interparticle forces leading to an aggregation phenomenon that generates a decrease in the surface area. In order to improve the process efficiency, the use of grinding aids, such oleic acid, has been tested. The adsorption of the oleic acid on the particle surface is found to prevent the aggregation through an electrostatic effect that allowing the surface area to be increased.
