SIZE DISTRIBUTION OF MAIZE MILLED PARTICLES OBTAINED BY USING A HAMMER MILL

Ioan BUDĂCAN, Dumitru POP, Ioan DROCAŞ

Abstract


The size distribution of the ground particles is an important indicator due to which the quality of the final particles resulted from grinding process is measured. For example, in the animals food industry in order to get the desired recipe, the proper dimension  of the feed particles is settled and that’s the target dimension that need to be obtained after the grinding process. In the present study the particles size distribution of ground maize particles was measured with a vibratory sieve shaker with sieve dimension of 2.5, 1.25, 0.63 and 0.5 mm. The grinding process was conducted with a horizontal hammer mill and for it three different sieve sizes were used: 4, 6 and 8 mm. For the determination of the maize ground particles size distribution, Rosin – Rammler function was used. The minimum coefficient of determination obtained was  The current research is useful for the determination of the sieve dimension, hammer configuration and grains moisture level that must be used in order to obtain the desired dimension and size distribution of the ground particles.

Key words: sieve dimension, maize, grinding, Rosin-Rammler function, size distribution.
