Ultra Fine Hammer Mill-Grinding Feed Ingredients to Meet Fineness Needs of Aquatic Feed
With the rapid development of aquaculture industry the demands of aquatic feeds dramatically increase. However the aquatic feed has higher requirements on particle size of feed ingredients, feed pellet viscosity and feed pellet quality. The poultry feed processing technology can not achieve the requirements of aquatic feed. Feed ingredients grinding is an important process for aquatic feed.
Aquatic animal’s digestive tract is relatively short so they have poor digestive ability. For example fishes have no salivary glands in the oropharyngeal cavity so feeds can not be digested. The functions of oropharyngeal cavity is to seek, intake and swallow feeds. The functions of tearing and grinding feeds degenerate. Fishes dissolve and digest feeds from the feed surface so feeds with small particle is convenient for digestion and absorption then help improve the feeds’ conversation rate.
Aquatic animals live in water and the feed intake is finished in water environment so feeds must keep steady shape in water for a long time. The interior of feed pellets should have a certain of viscosity to maintain the shape and avoid rapidly dissolving. Apart from the added binder, grinding process has a great influence on its viscosity. Feeds have little viscosity when grinded with big particle size. The other way around if feeds are grinded with small particle size they have great viscosity and can keep the steady shape in water for a long time. The particle size of grinding feed ingredients also has great influence on the follow-up processes such as mixing and pelleting and the quality of finally manufactured feed pellet.
Grinding process is very important for aquatic feed pellet processing so it needs to customize the feed hammer mill. Our company supplies the ultra fine grinding mill for making aquatic feed. And we also manufacture the hammer mill crusher according to your requirements. All we do is to supply the first-class grinding machines to our customers.
