Introduction As particle size research has continued to evolve, so has the nutritionist’s understanding of what is needed to optimize animal performance. There is a push to begin manufacturing diets of specific particle sizes to account for differences among species and growth phases. This may appear to be a relatively easy task for the feed mill; however, as the grinding limitations of th...

Coarseness of feed is very pertinent issue which is correlated with
Rpm of hammer mill motor
Weight and shape of hammers
Number of hammers
Tip of hammers
Size of screen holes
Effective magnetic control at intake point
Synchronised intake of Raw materials
These have been my observation
