Product Description

Customized Ring die for livestock feed pellet press machine 
Ring die for Pellet Mill/Pellet Press/Pelletizer 

 
Other spare parts for pellet mill
 
 
Good tensile strength, Good abrasion resistance, Good corrosion resistance, Good impact resistance, Good heat resistance, Good fatigue resistance.

Application:
Ring die for pellet machine in poultry feed, livestock feed, aqua feed, bio-mass pellet machine, etc.
We could offer you OEM high chrome steel ring die, such as for CPM, Buhler,
Andiritz, Muyang, Zhengchang pellet mill with different specification.  
 
 

Type	for feed pellet mill, bio-mass pellet mill
Pattern	honey-comb, teeth,etc
widely application	CPM, Buhler, Andiritz, Muyang, Zhengchang pellet mill,etc

Features of our ring die:
1. Made of imported high-carbon high-chromium stainless billet steel, optimization carbon, thus enhancing
wearing and corrosion resistance and hardness.
2.  It can deal with all kinds of die hole over &1.2mm (&1.2mm included) and compression ratio.
3. Ring die can be produced up to 300mm-1500mm in diameter  and 500mm in height.
4. In ring die processing, full automatic control, one-time molding for die hole, high smoothness.
 strong tensile strength, good wear resistance, good corrosion resistance, high wear resistance, long life
 
Advantages of our ring die:
1. Material refining technology, fewer impurities, high purity, largely reducing harmful
elements content (such as elements S,P ), thus comprehensive mechanical performance
of material is raised.
2. Through roll forging, material is processed and strengthened and material fibre is 
complete and uniform, which increases integrated mechanical performance of material.
3. FDSP Company has the world advanced forging equipment and technology, electronic data processing systems and perfect quality control system.
4. Ring die blank, generally chromiumalloy roll forgings, some factories use 45 
ordinary carbon steel.
5. Hardness of blank must be controlled, ranging from HB170 to HB220. If the hardness 
is too high, the drill is easy to break and happens with die hole when drilling. If hardness
is too low, the surface finish of die hole will be not good.
6. In order to control blank inner material uniformity, every blank must be carried out with
fault detection, which can avoid defects such as flaw, pore-free, crackle and inclusions
etc.
7. After machining and heat treatment process, hardness of ring die can be up to HRC 
52-58 (inner diameter less than 350mm), HRC50-56(inner diameter more than 350mm), more wearable and anti-corrosion.
8. In order to control hardness uniformity of ring die after heat treatment, we choose 
more than three points in each part of trisection of peripheral direction to test hardness 
and take average.The difference of hardness value between each part should not be higher than HRC4.
9. According to the principle of metal material science combined with gas quenching and 
C, Cr, Mn, Ni, V elements content is optimized, forming the standard of ring die.
 
 
Relations between die hole structure and pelleting:
Straight hole and release stepped hole is suitable for compound feed processing
External conical hole suitable for the processing of high-fibre feed like de-fat chaff
Internal conical hole and compression-type stepped hole applicable for the process of 
herbage powder feed of light proportion
We should try to avoid using release stepped hole(pressure-relief vent)
Because discharing is not easy for holes in the rows of the edge of ring die, pressure-relief vent is designed there.
 
Production process:
1.Precision Machining:
CNC machining center
CNC machining center assure high dimensional accuracy,geometric tolerance and 
surface roughness.
2.Hole Machining
Germany gun drill
The quality and service life of die is guaranteed.
3.Vacuum Hardening
