7. Machine highlights
 Triple rollers
 Double-motor timing-belt stepping drive
 Hydraulic overload protection

8. Triple rollers
 Balance stress distributed on the ring die can protect it from broken;
 Triple working zones greatly increase the production capacity of a pellet mill;
 Each roller corresponds to a cutter, the pellet length can be controlled reliably;
 Feed pellets have longer retention time in die holes and obtain better durability and
appearance; (compared to 2-roller pellet mill)
Especially suitable for the production of high-grade fish feed.

9. Triple rollers

1 roller
1 working zone
S
3 rollers
3 working zones
The increased working zones maximize the utilization of effective working area of a ring die.
Subject to the same capacity, the more the rollers applied, the longer the product staying in
the die hole and the better the pellet quality achieved.

•
Recommended for
laboratory
• Of better mechanical
strength, and contributing to
more uniform stress
distributed on the ring die
•Recommended for
poultry feed and livestock
feed production
•The most balance

12. Two-motor timing-belt stepping drive
 Transmission efficiency as high as that of gear drive
 Flexible drive, more stable and lower noise than gear
drive;
 Unlike gear drive, it is free of lubrication, more
convenient for maintenance and replacement.

13. Two-motor timing-belt stepping drive
 Double-motor drive contributes to uniform stress distributed on main
shaft bearings, of which the service life could up to 5 years.

14. Hydraulic overload protection
□ Hydraulic brake type
Advantages:
1. Hydraulic brake type to replace
shear pin type, overload protection is
more safe and reliable;
2. Production can be restored quickly
after overload;
3. Hydraulic take-up system to keep
the V-belts at both two sides
tightened with a same tension.
Disadvantage:
Compared to shear pin type, it is
complicate in structure and a little bit
expensive.

18. Ring die
Excellent workmanship
 Made of forged high chrome alloy steel;
 Advanced gundrill technology to guarantee
position accuracy as well as surface
roughness of die holes;
 Vacuum quenching treatment applied to
harden working surface and diminish
deformation of a ring die.
Apply advanced die hole
arrangement technology to
maximize the effective working
area of a ring die.
Smooth die holes to allow
the ring die engaging in
pelleting production
directly without flushing .

19. Important parameters
 Effective working area S
S=Π*D*L
 Opening ratio ψ
ψ=N* （ Π*d2 ） /4S
N——numbers of die holes
 Linear velocity of ring die V
V=Π*D*n
n——rotate speed of ring die, rpm
 Compression ration of die hole i
i=d/h

20. Important parameters
Linear velocity of ring die V
 The linear velocity of ring die is
related to the performance of
pelleting production and pellet
quality.
 Appropriate linear velocity of
ring die: 7-8 m/s.

21. Important parameters
 Compression ratio
Compression ratio is an important index to indicate the pressing strength of
pellet feed. The larger the compression ratio, the longer the retention time and
the more durable pellet.

Fish feed 1:14 ～ 1:16;

Poultry feed 1:9 ～ 1:15.

22. Important parameters
 Roughness
 Roughness of die hole is an important factor that will influence the production
capacity as well as the surface quality of pellet feed.
 The appropriate roughness of die hole: 0.8-1.6

23. Roller

24. Roller shell
Common roller shell----adaptable to different materials
Open-ended corrugations
Closed-ended corrugations
Recommended for poultry

production
Recommended for

25. Roller shell
Customizable roller shell---- more wear-resistant
Dimpled roller shell
Helical corrugations
Herringbone corrugations
Dimpled roller shell is recommended for poultry & livestock feed production
