Clinker granulometry during petcoke. - Page 1 of 2

Re: Clinker granulometry during petcoke. The change in clinker granulometry with petcoke firing is caused by the sulphur content of the petcoke. This sulphur changes the viscosity and lowers surface tension of the flux in the kiln. This means that the flux is more mobile and the solid phases are more easily "wetted" by the flux.

Particle-size distribution - Wikipedia

The particle-size distribution (PSD) of a powder, or granular material, or particles dispersed in fluid, is a list of values or a mathematical function that defines the relative amount, typically by mass, of particles present according to size. Significant energy is usually required to disintegrate soil, etc. particles into the PSD that is then called a grain size distribution.
