It is suspected that the poorer reproducibility of results by air-jet sieving is due to balling of fine dry cement. There was more clogging in the wet-sieving operation even though its results were more reproducible. 3. The method of fineness determination in terms of specific surface is superior to the air-jet sieving method using the No. 200 ...

WhatsApp: +86 18221755073Wet sieving: A special case of vibratory sieving is wet sieving. Agglomerates, electrostatic charging or a high degree of fineness can all make the sieving process difficult and in such cases wet sieving may be called for. This involves washing the sample through the sieve stack in a suitable medium which is usually water.
