For the latter, research suggests a feed particle size between 600 and 900 microns is ideal. Studies also show that particle size is more important for mash diets than pellets. Evaluating Different Particle Sizes of Animal Feed. Regularly evaluating your grain feedparticle size is essential for producing the highest quality product.
RECOMMENDED FEED PARTICLE SIZE Feed particle size has a large impact on the chickens' feed intake, dusty feed particles (<0.5 mm) will reduce feed intake greatly. We advise to increase the feed …
The equation used in fine grinding is shown as Equation (3). The P80 term overwhelms the F80 term in Equation (2) at fine sizes, so the feed size is negligible and can be dropped. Moreover, in a regrinding application, the concentrate feed size is usually fixed and does not vary with different regrind mill circuit equipment or configuration. E ...
