ring die pellet mill is a kind of large pellet mill which is designed for making powder raw material into animal feed pellets and sinking fish feed pellets. this large pellet mill is the major equipment and indispensable equipment in feed production process. It is with large capacity of 1-20t/h, and can make pellet size from 1.5mm to 12mm whihc is very suitable for medium or large feed processing factories.ring die large pellet mill are one type of the hot pellet mills in the world. Comparing with flat die pellet mill, ring die large pellet mill should be not so widespread for its increasing complexity and higher costs.this large pellet mill can make aqua feed pellets like sinking fish feed.this sinking fish feed pellet mill can ensure the final production pellets quality.
But the ring die sinking fish feed pellet mill are the definite choice to conduct a large scale fish feed pellets and poultry feed pellets producing for industrial or commercial purposes. Just as its name described, this larg sinking fish feed pellet mill machine has a wide cylindrical die and is mounted vertically, rather than flat and horizontally as with a flat die. When you are going to put the powder raw materials inside the sinking fish feed mill door, you can feed them with a surge bin to make them through a variable speed conditioner. A screw auger is significant for the last step to sending materials into the pelletizing machine chamber.
The extrusion die is circularly vertical with a series of rollers indside. Both the rollers and the die operate on the vertical axis, and therefore the inner and outer edges of the rollers cover the same distance across the surface of the die. Thus, the raw materials cannot be skipped being compressed by the ring die and rollers, which extends the service life of both ring die and rollers. When making pellets, the raw materials are compressed into the holes in the ring die to form pellets. And a series of rollers besides the ring die will cut the emerged pellets into the same length. Then, the uniform pellets are thrown out of the large fish feed pellet mill.
Benefits Of The Ring Die Design
One of the main reasons that this is a superior design to the flat die press is that it does not suffer from roller skip. Due to speed differences between the point of contact between the rollers and die, roller skip is a significant issue for flat die pellet machines. Ring die systems do not suffer from this issue as there is no difference in speed between the die and rollers at any position.
Advantages of Large Sinking Fish Feed Pellet Mill
• Large capacity: ring die large pellet mill is specialized in large-scale business, such as commercial animal feed pellet production. Its large capacity range covers from 1 ton/h to 20 ton/h. Larger capacity pellet plant is realized by connecting several ring die pellet mills in parallel, in that case, you can reach a capacity up to 20 ton/hour.
• High density: compare to the flat die pellet mill, the pressure of the ring die large fish feed pellet mill is much higher so that the pellet it makes has a higher density and smoother surface. The higher the density is, the higher combustion value it has.
• Cost-efficient: our ring die large pellet mill uses the German bearings and oil seal so that it is much more stable than others. Also, compare to the small pellet mill, during the pelletizing process, both edges move the same distance, so the roller and die wear evenly, it can save the replacement part.
• make pellets from different raw materials: our ring die large pellet mill can process soft wood, logs, branches, bark, sawdust, corn meal,grass meal,straw meal,bone meal,hay meal, grass straw, peanut shell, rice husk,etc. All material is practically proven by our clients.
