Product Description

Stainless Steel Ring Dies for Feed Pellet Mill Matrix customized Stainless Steel Ring Dies for Feed Pellet Mill Matrix Customized

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.  

 
Typefor feed pellet mill, bio-mass pellet mill
Patternhoney-comb, teeth, etc.
widely applicationCPM, Buhler, Andiritz, Muyang, Zhengchang pellet mill, etc.

Features 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 hardnessis 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 withfault 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 morethan 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.
