TUV ISO SGS Approved Wood Pellet Mill Die

Weikeer can manufacture different kinds of ring dies according to clients’ requirements
The products are widely applied to large, medium & small-sized aquaculture, food and feed mills, livestock farms, poultry farms, individual farmers and small & medium-sized farms, farmers or large, medium & small-sized feed mills, which are feed processing machinery for directly pressing corns, bean pulp, straws, grass, rice husks and other shattered objects into granules.

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.

Introduction of pellet machine ring die

1. Material of the ring die:  X46Cr13 /4Cr13(stainless steel), 20MnCr5/20CrMnTi (alloy steel) or customized
2. Hardness of ring dies: 52-60 HRC
3. Diameter of ring die can do: 1.0mm up to 28mm
4. Pellet die type can do: Ring Die or Flat Die
5. Outer diameter can do: Outer diameter up to 1800mm
6. Pellet Die model we can customize:
CPM, Buhler, CPP, OGM, Zhengchang(SZLH/MZLH), Amandus Kahl, Muyang(MUZL), Xihu (West Lake) Dis.(XGJ), AWILA,PTN, Andritz Sprout, Matador, Paladin, Sogem, Van Arssen, Yemmak, Promill; etc. We can also customize for you according to your drawing. 

Relation between die hole structure and pelleting
1.Straight hole and release stepped hole
It is suitable for compound feed processing

2.External conical hole
It is suitable for the processing of high-fibre feed like de-fat chaff

3.Internal conical hole and compression-type stepped hole
This 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.
 
We need to maintain and check the pellet mill’s spare parts: ring dies, roller assembly,roller shell, gear shaft,screws, bearings, coupling etc. Because they are take up about 8% of the machine cost every year (primary for such as wood chipper, hammer mill and pellet mill.) 

Specification customized: 
We can supply ring die for all the main brands of pellet machine such as ANDRITZ, CPM, ZCME, IEMME, JKAP, SOGEM, SPROUT(UMT), MATADOR(UMT), MABRIK,BUEHLER, PALADIN, PTN, YIAD,JIATONG,PROMILL,YEMMAK etc.Custom dimensions and drawings of ring die are welcome. 

Following are the normal Model of each brand:

Main Manufacturing Process of Ring die

1.Forging and Lathing:
Extremely precise forging and lathing assure high dimensional accuracy, EPT and clean surface.

2.Die Hole processing:
Advanced Germany gun drill equipment, tools and drilling hole software are used in  die hole processing:
High accuracy of die hole positon;
High rotating speed and imported tools and cooling liquid ensures process conditions as drilling required;
Small roughness of the processed die hole, ensure pelleting output and quality;
Quality and service life of die is guaranteed.

3.Vacuum heat treatment
Function:
Ring die surface:No oxidation reaction;
Die hole inner surface:Original smoothness;
High stability, High hardness;High tenacity

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.
Buyers can customize dies with different hole diameter and compression ratio, according to different situation and requirement.

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.
