After grinding, 95 percent of the feed ingredients should be less than or equal to 250 µm (Tan and Dominy, 1997) and for smaller shrimp, 150 to 180 µm (Chamberlain and Bortone, 2006). In shrimp feed mills, ingredients are ground after weighing and mixing, providing a more uniform particle size distribution (Chamberlain and Bortone, 2006).
