Product Description

Stainless Steel Ring Die for Pelletizer Mill
 ---Ring die for Pellet Mill/Pellet Press/Pelletizer 

---Ring die for wood pellet machine, bio-mass pellet machine
 
Other spare parts for pellet mill 
Good tensile strength, Good abrasion resistance, Good corrosion resistance, Good impact resistance, Good heat resistance, Good fatigue resistance.

Applications:
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, result to the excellent performance like high smoothness, strong tensile strength, good wear resistance, excellent corrosion resistance and long life etc. 

Advantages of our ring die:
1. Material refining technology makes high purity and low harmful element content (such
as S,P ).
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
 
America vacuum furnace:
1. High vacuum degree, no oxidation reaction in ring die surface, ensuring original 
smoothness of die hole inner surface.
2. High vacuum degree, twisting bottom and convection heating minimize ring die 
deformation.
3. CNC controls process program, ensuring ring die quality stability.
4. With rationally adjusting heat treatment, heat preservation and cooling rate and time, 
microstructure of ring die can achieve its most suitable working conditions.
5. High cooling speed ensures more even distribution of carbide and hardenability and 
uniformity of ring die is guaranteed, contributing to balance using of ring die.
