    Aug 11, 2017· During any sieving process, there is a constant size comparison between particles and sieve apertures. A particle will pass the mesh if it is smaller than an aperture and when it does not pass the aperture it is thrown upwards with subsequent lifting of the sieve bottom, takes a different orientation – which is vital with longish particles – and hits the mesh again for a new …
