Product Description
Introduction of Ring die
Ring die is very important part of ring die pellet machine in the whole manufacturing process. The quality of ring die not only directly relates with the quality and output of pellets, but also the running state of equipment and maintenance cost.
Applicable for Biomass pellet machine: wood pellet mill, sawdust pellet mill, grass pellet mill, straw pellet mill, crop stalk pellet machine, alfalfa pellet mill etc.
Applicable for Fertilizer pellet machine, animal feed pellet machine too.
Specification customized:
We can supply ring die for all the main brands of pellet machine such as ANDRITZ, CPM, IEMME, JKAP, SOGEM, SPROUT(UMT), MATADOR(UMT), MABRIK,BUEHLER, PALADIN, PTN, PROMILL,YEMMAK etc.
Custom dimensions and drawings of ring die are welcome!
Application:
Ring die for pellet machine in poultry feed,livestock feed,aqua feed, bio-mass pellet machine,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 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.
Production Process
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.
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. Good quality gun drill equipment, tools and drilling hole software:
1.Die hole position high accuracy, up to 15 seconds per circle. High accuracy of position
ensures both high dimensional accuracy and uniformity of materials and uniformity in die
wearing and forces of radial direction and peripheral direction.
2.High rotating speed and imported tools and cooling liquid ensures process conditions as
drilling required.Thanks to such conditions, the processed die hole features small roughness, Ra 0.8 and smoothness, which can ensure pelleting output, quality and debugging
convenience.
3.The application of drilling hole software is favorable to increase porosity of ring die and
optimize its way of aperture and therefore pelleting output, quality and service life of die is
guaranteed.

Compression Ratio of Ring Die
Generally speaking, the higher the compression ratio, the denser the finished pellets. But it does not mean that the higher the compression ratio, the better the pellet quality.
Compression ratio should be calculated based on raw material for making pellets and type of feed.
With many years pellet die manufacturing and research experience of FDSP GROUP, we provide some general data of ring die's compression ratio for your reference:
Buyers can customize dies with different hole diameter and compression ratio, according to different situation and requirement. | Hole Diameter(mm) | Compression Ratio |
Ring die for animal feed pellet machine | | |
Poultry&livestock feed | 2.5 - 4 | 1:4-1:11 |
Fish feed | 2.0 - 2.5 | 1:12-1:14 |
Shrimp feed | 0.4 - 1.8 | 1:18-1:25 |
Ring die for biomass pellet machine | | |
| 6.0 - 8.0 | 1:5-1:8 |
The most common structure of die hole are straight hole; release stepped hole; external conical hole and internal conical hole, etc. Different die holes structure are suitable for different raw material and feed formula for making pellets.
WARM TIPS
How to maintain and inspect the ring die:
1. The rollers should be correctly adjusted, make sure the hole inlets are not damaged by contact with the rollers or as a result of tramp metal.
2. Material should be evenly distributed across the whole working area
3. Make sure that all holes work uniformly, opening the clogged holes if necessary.
4. When changing dies, carefully inspect the condition of the die seating surfaces and fixing systems including collar, clamp or wear ring.
