Product Description

 Compact structure sheet metal die maker pellet mill ring die
Ring die 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

Feature of our ring die:
1.Made of imported high-carbon high-chromium stainless billet steel,optimization carbon,thus enhancing wearing and 
corrosion resistance andhardness.
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 300-1500mm in diameter  and 500mm in height.
4.In ring die processing, full automatic control, onetime molding for die hole, high 
smoothness.
strong tensile strength,good wear resistance, good corrosion resistance, high wear resistance,long life
 
Advantage 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 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 
with fault detection, which can avoid defects such as flaw, porefree,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 
hardnessand 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.
  
Relation 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.


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 anduniformity of ring die is guaranteed, contributing to balance using of ring die.
