Realtime Monitoring Of Different Grinding Phases In A Disc

During grinding of clinker, we were able to identify three clearly distinguishable phases, i.e. breakage, plateau and agglomeration phase. in the breakage phase, impacting stress leads to particle fragmentation below 45 m. in the plateau phase, attrition results in ultrafine particles which eventually cause the formation of agglomerates.
