Clinker granulometry during petcoke

07 02 2009  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.
