    2.2. Approach. To evaluate the effect of the classifications of particle-size distribution of cement, the mix proportion was newly required. Nine mix proportions by the amount of different sizes of cement were classified based on the accumulated remains denoted as R at 10 m (R10), 20 m (R20), 40 m (R40), and 80 m (R80) using an Alpine air jet sieve shaker, as shown in Table 5, and the fineness .

    Cement can be a problematic material in the application of particle size analysis. First, the size distribution itself is extremely broad, extending in most cases over two to three orders of magnitude, from about 100 µm down to below micrometer size. In general, sizing techniques work best over a limited size .

    A particle of negligible size and mass m just remains in contact with the mill lining at the "12 o'clock" position if the centrifugal effect (mv 2 /r) is equal to the gravitational force (mg), where v is the peripheral velocity in m/s and r is the radius inside the lining in metres. The circumference of the mill is 2πr metres so v = 2πrN/60 .

  • 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.
