CLINKER STORAGE SYSTEMS - irp-cdn.multiscreensite.com

During the loading process, the clinker segregates and forms cones according to the particle size. A homogenous clinker mixture is, however, an essential condition for the performance of cement mills. Therefore, it is recommended to systematically shift the silo discharge gates in order to blend the different particle sizes in the silo.

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.
