scope: the purpose of this method is the rough determination of the particle size and distribution of ground cereals and milling products with a moisture content of max. 16%. definitions the particle size is defined as the quantity of ground cereals remaining in sieves of specific mesh aperture after the sieving process, plus the screenings of the finest sieve used..maize - world food programme,- place the sub sample on a 4.5mm round hole sieve and sieve it in such a manner that all the material on the sieve passes at least 20 times over the entire surface of the sieve. - remove defective grains and all other substances which would be retained.effects of different milling methods on physicochemical properties of common buckwheat …,common buckwheat rice was ground using a high-speed universal grinder (fw-400a, beijing zhongxingweiye instrument co., ltd, beijing, china) for 2 min. during the milling process, the roll speed was 26000 rpm. the flour passed through a 90-mesh sieve.fm 306: size reduction and sieving - iit bombay,3. weigh the mass of lime stone retained on each sieve. 4. load lime stone to the ball mill along with metal balls. 5. run the ball mill for 40 minutes at the speed 1 rpm. 6. after 40 minutes take out lime stone powder from the ball mill. 7. fill the lime stonefor 20 5
