    These consist of a pair of rollers set 8–30 mm apart and counter-rotating with surface speed around 0.9 - 1.8 m.s . The bearings of the rollers are designed to deliver a pressure of 50 MPa or more. The bed of material drawn between the rollers emerges as a slab-like agglomeration of highly fractured particles. The energy efficiency of this process is comparatively high. Systems have been designed, including a de-agglomerator and separator, that will deliver material of cement fineness. However, particle size distrib

  • Measuring the Particle Size Distribution of Cement

    2008-04-15  Measuring and controlling the particle size distribution of cement is important both in order to achieve the desired product performance and to control manufacturing costs. Historic techniques of sieve and air permeability are still in use, but laser diffraction is becoming a more popular method to determine the particle size distribution of cement. The laser diffraction technique is quick ...

  • 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.

  • Particle size analysis reduces cement manufacturing

    Particle size is an important parameter for cement because of its influence on the rate at which hydration reactions occur, when the product is mixed with water during use. These reactions dictate cement performance in the field. Very fine particles, two microns and below, hydrate rapidly and can cause the cement to cure exothermically, set too quickly and crack. Conversely, much larger ...
