Some factors affecting sieving performance and efficiency

2009年7月25日 The observed difference in sieving efficiency and performance and in sieving loss between the two sieving methods can be attributed to the beneficial effect of oversized particles, since during sieving, the presence of oversized particle can reduce sieve blinding caused by near or sub-sieve sized particles.
