Wood Pellet Machine Parts Ring Die Customized

Ring die is the key parts in WOOD PELLET MACHINE, its structure and quality of ring die largely affect the performance of pellet mill and quality of finished biomass pellets even big influence in running state of equipment and maintenance cost.

Why choose we as ring die tailor made ?

The material : Alloy steel(20CrMnTi) and Stainless steel (4Cr13)

Alloy structural steels, such as 20CrMnTi, 40Cr, 35CrMo, have hardness of heat treatment above HRC50 and good comprehensive mechanical properties. The ring die made of these materials has high strength and good wear resistance, but its shortcoming is poor corrosion resistance. Stainless steel materials are X46Cr13 (German brand), 4Cr13, 3Cr13, etc. These materials are rigid. The hardness of heat treatment is higher than HRC50, and it has good wear resistance and corrosion resistance. It has a long service life.

Our producing base is in Liyang ,Jiangsu ,which is known as town of pellet mill .We have experienced processing equipment and engineer ,for the material ,each chemical ingredients will influence the durability of ring die ,what we used material provided by best and large scale supplier in Liyang .

1. Material of the ring die: X46Cr13 /4Cr13(stainless steel), 20MnCr5/20CrMnTi (alloy steel) or customized

2. Hardness of ring dies: HRC54-60.

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 as your specified drawing .

The processing of ring die made :

Blank raw material Forging---Rough turning---Half finished turning---Drilling the hole---Grinding inner bore---Treaded hole--- Keyway milling---Heat treatment---Finish turning---Package

2.Compression Ratio of Ring Die
The ring die compression ratio refers to the ratio of the effective length of the ring die hole to the minimum diameter of the ring die hole. It is an index reflecting the extrusion strength of pellet feed. The bigger the compression ratio is, the stronger the pellet feed is. But not mean the higher ratio is ,the better it is .
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 , 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.

Ring Die Maintenance:
1. When the ring die is not used for a period of time, the original material should be extruded with non-corrosive oil. Otherwise, the heat of the ring die feeding originally left in the die hole, thus producing the following situation:·
When starting the operation, the die hole is blocked and the material is not discharged;·
When starting production, the ring mold is subjected to high stress and weakens its strength, which may cause ring mold cracking;· Part of the die hole is blocked, the output is reduced, and the benefit is reduced.
2. When loading and unloading the ring die, do not hit the ring die working surface with a hard steel tool such as a hammer.
3. The record of each shift of the ring dieshould be done in order to accurately calculate the actual service life of the ring mold.
4. The ring die must be stored in a dry and clean place. If it is stored in a damp place, it will cause die hole corrosion, which will reduce the service life of the ring mold or not discharge.
