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.  
 
Features
1Made 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.
3Ring die can be produced up to 300mm-1500mm in diameter  and 500mm in height.
4In 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
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.
 
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.

FAQ
1.Where you go to buy good quality wood pellet machine in China?
Nowadays many overseas importers have confusion facing hundreds and thousands of Chinese wood pellet machine suppliers from B2B sources or Google. From Geographic point of view, best wood pellet machine suppliers concentrate in Southeast part of China, this Geography represents:
1.Highest level development of economy in China, namely, richest place in China. 
2.Having highest standard of manufacturing, 
3.Huge investment of R&D for sustainable development, 
4.Most talent experts and profession workers, best tooling machines. 
So go to Southeast part of China to find qualified wood pellet machine supplier. 

2.How to choose qualified wood pellet machine supplier in Southeast part of China?
Tips:
1.When suppliers' hardware reaches same level, the most comparable part is software incl. management, credit, culture, value. Test suppliers' software before business. 
2.Seeing is believing, try to avoid dealing with trader who you are not familiar, in case of fraud. Visit supplier if you can. 
3.Good company always hires best sales manager, good sales manager means fully communication, fully understanding, fully support, and always give good solutions at any times to solve client problems. 

3,BASIC RULES FOR THE CORRECT USE OF DIES?
Make sure that the rollers are correctly adjusted: the roller to die distance must be o.2mm-0.3mm. A bad roller setting can cause contact between rollers and die. This may cause" rollover"on the die hole- deformation and partial blockage of the holes.
A new die requires arunning-in period. Start new die progressively, at least for the first 20-40 minutes, so they warm up slowly. If problems are encountered during start up, operate the die for 20-40 minutes with a mix of bran, oil (2%). When production is finished, only stop the die after running it on oats or maize.
When changing dies, carefully inspect the condition of the die seating surface and the fixing system( i.e. collar, clamp or wear ring). N.B.: if the die is not properly fixed it can break.
The die clamping ring should be checked every time a new die is mounted on the machine, especially for dies with large flanges. Experience shows that the majority of broken dies are caused by worn out or defective clamping rings. Dies running with a defective clamping ring can create strong vibrations, broken dies and a reduced die lifespan.
