Tap sieve shakers are specified in various standards for particle size analysis. The number of comparisons between particles and sieve apertures is substantially lower in tap sieve shakers than in vibratory sieve shakers (2.5 s1 as compared to ~50 s1) which results in longer sieving times. On the other hand, the tapping motion gives the
