Products Description
Biomass pellet ring dies are core components of biomass fuel pelletizing equipment and are widely used to pelletize high-fiber raw materials such as sawdust, straw, rice husks, coconut shells, bamboo powder, and palm oil. Due to the high hardness and fiber content of biomass raw materials, the ring die structure requires higher strength and wear resistance.
JIUHE's biomass pellet dies are made of high-strength alloy steel or stainless steel, incorporating deep-hole drilling, high-temperature quenching, and vacuum heat treatment technologies. They offer excellent wear and heat resistance, as well as long-term stable operation.

Remark: Opening rate of pellet die depends on the thickness and application finally.lf the die is not thick enough, opening rate shall be decreased appropriately to avoid crack.
Product Features
·Material: X46Cr13 & alloy steel
·Diversified die holes, including straight holes, stepped holes (release/compression), external tapered holes, etc., suitable for different raw material characteristics (such as cellulose, straw) and particle density requirements.
·Jiuhe biomass pellet ring molds customize the compression ratio and die hole structure according to the characteristics of different materials such as sawdust, bamboo chips, straw, palm, peanut shells, etc. to ensure the pellet forming rate and density.
·After vacuum quenching treatment, the die hole structure is stable, not easy to deform, and the service life is extended.
·Service Time: 400-1000Hours
Our die is characterized by its special distribution of holes. The relative position and pattern of our die holes improve optimum capacity of the pellet mill. The unique hole distribution of the die ensures:
1. Longer life (even wear)
2. Higher capacity with the same Die open area
3. Lower power consumption per ton of produced product
Pellet Die Type
JIUHE MACHINERY can customize the out shape and hole shape of the pellet die according to pellet type, raw material, customer demand and application. Mould shape: screw type with bevel edge,screw type with straight edge,clamp type.Hole shape: straight hole,straight hole with single relief,straight hole with multi relief,straight hole with conical relief.

Production Application
Applicable fields: Particularly suitable for wood fiber materials (wood chips, branches, sawdust), straw, rice husks, etc., with moderate moisture content requirements (12%-15%); Can process complex structure raw materials (such as palm shells, fungus residue), but need to be pre-processed to particle size ≤ 5mm; Large-scale production scenarios such as industrial fuel pellets (high density) and feed pellets.
Tips
The core advantage of biomass pellet die lies in its high-yield, high-density pellet forming capability and the stability of large-scale production, which is particularly suitable for industrial scenarios with strict requirements on pellet quality and output.
Its vertical structure design, wear-resistant alloy material and intelligent control system further improve energy efficiency and durability, but attention should be paid to raw material pretreatment (particle size, moisture content) and regular maintenance to achieve optimal performance.
