dental grinding particle size

At the feed mill, the feedparticle sizeaveraged 755 microns. With the hammer crushers installed on farms, the particles were of different sizes. As a result ofgrindingon the farm, particles were obtained with an averagesizeof 1029 microns, at the feed mill - 730 microns. The economic effect of changing theparticle sizecan be enormous.
