What is Ring Die Pellet Mill Machine?
Ring die pellet mill machine is another popular type. They have higher production capacity than flat die pellet machine, In contrast to flat die pellet press machines, ring die pellet mill is more often used for commercial and big capacity plant like chicken feed, pig feed, duck feed, fish feed, cattle feed etc. The finished feed pellets have a smooth surface and easy to digest for animals. The ring die has a wide cylindrical shape and is mounted vertically, rather than flat, ring die pellet machine adopts mature technology to make high quality animal feed pellet with large-scale production.
It offers large capacity of 0.5-10t/h, and can make pellet size from 1.5mm to 12mm. 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 15-20 ton/hour.


Application Raw Materials of large ring die pellet mill
Cereals: soybean, soybean meal , maize/corn, corn flour, grain, sorghum, wheat flour, etc.
Coarse fiber: crop stalks (corn stalk, sorghum stalk, cotton stalk, rape stalk, peanut seedling, sunflower stalk), chaff, grass, grass meal, alfalfa, wheat bran, rice husk, grass, groundnut shell, cotton seed shell etc;
Additives: molasses, vegetable oil, amino acids, bone meal, vitamins, etc; Generally, the raw materials for ring die pellet making machine are cereals(100%) or cereals(60-80%) and coarse fiber(20-40%).
Why Pelleted Feed Good for Poultry and Animal?
Pelletizing is a key process to the production of high quality poultry feeds as it ensures that the feed formulation with rich nutrition and in the correct quantities for poultry. Each bite of a pellet made by our ring die poultry feed pellet machine will have the same quality to improve the animal performance.
★ Improved animal performance ★ Decreased feed wastage ★ Reduced selective feeding ★ Destruction of deleterious organisms


Structure and Working Principle of Ring Die Pellet Mill
The material is put into the screw feeder which can be easily adjusted for the feeding speed and getting proper material flow. After this, the material goes into a conditioner where hot steam can provide favorable conditioning. Then, the material temperature is maintained at about 75°C – 95°C and moisture between 14-16% before entering the pressing chamber. In the pressing chamber, materials will naturally be compressed into pellet form through the die holes under the high pressure of rollers.
Features & Advantages of Ring Die Pellet Mill
Core Mechanical Advantages:
There are two main advantages in using ring die pellet mill. First, generate less wear and tear since both the inner and outer edges of the roller traverse the same distance. Second, more energy-efficient than the flat die design.
Equipment Features:
- ring die pellet mill adopt one layer jacket conditioner, the material can be fully cooked, meet special needs and ensure quality of final aquatic feed.
- Main driving adopts high precision gear transmission , the capacity can be improved 20% higher transmission efficiency comparing to the belt transmission, and with low energy-consumption.
- Multiple aperture ring die for choice, High-chrome stainless steel die with 800-1,000+ hours service life to make smooth and high quality aquatic feed pellets.
- There is a variable frequency drive feeder to control the feeding amount in order to reduce material blockage.
- Users do not have to stop the pellet machine to lubricate it.
- This type of commercial pellet mill is controlled by PLC system, which makes it convenient to operate and saves labor cost.
- All the transmission parts of the pellet mill adopt high quality imported bearings and oil seals to guarantee high efficiency transmission, stability and low noise.
- The all-stainless steel feeder, configured with original import frequency converter to control, feed evenly and accurately.
- The ring die of industrial feed machine with quick-release coupling can reduce the time of replacing the ring die to improve the production efficiency.
- Feeder spindle, screw, sleeve, paddle are 304 stainless steel.
