Brief Introduction
The peanut shell pellet mill is a vertical ring die biomass pelletizing equipment, specifically designed to address the lightweight, fibrous, and easily bridging characteristics of peanut shells. The equipment extrudes waste peanut shells into high-density cylindrical biomass fuel pellets, achieving the resource utilization of agricultural waste. This mill is also compatible with various agricultural and forestry materials and is widely used in rural processing plants and biomass fuel projects. The finished pellets meet domestic heating and export standards.
Working Principle
Vertical ring die physical extrusion molding is used, eliminating the need for adhesives.
Pre-treatment: Peanut shells are first crushed and then dried to adjust the moisture content to the optimal pelleting range of 12%–15%;
Feeding: Material enters the pelleting chamber vertically, effectively preventing arching and clogging of lightweight peanut shells;
High-pressure compaction: Pressure rollers and ring dies exert strong pressure on the material, and frictional heat activates the lignin in the peanut shells;
Extrusion and pelletizing: Material is extruded through the ring die holes, and a cutter automatically cuts it into uniform cylindrical pellets;
Post-treatment: The pellets are cooled and sieved to remove powder, resulting in compacted finished pellets that can be directly packaged and stored.

Suitable Raw Materials

Main ingredient: Peanut shells
Compatible raw materials: Rice husks, straw, wood chips, sawdust, branches, miscellaneous wood, alfalfa and other agricultural and forestry waste.
Application Areas
Biomass fuel industry: Peanut shell pellets are used as fuel in boilers, hot air furnaces, and heating stoves for factory heating, community heating, and drying equipment, replacing coal and reducing emissions.
Livestock and poultry farming industry: Processed peanut shell feed pellets are used in feed for ruminant animals such as cattle and sheep, improving palatability and reducing feed waste.
Organic fertilizer industry: Peanut shell pellets can be used as a substrate raw material for organic fertilizer, fermented to produce bio-organic fertilizer.
Export and foreign trade: Biomass fuel pellets meet CE and other standards and can be exported as clean energy pellets.
Household/small processing plants: Small-scale mill are suitable for farmers to process peanut shells locally for their own heating or to sell pellets to increase income.
Details
HUIXIN Gearbox: Heavy-duty HUIXIN gearbox delivers adaptive torque to handle moderate extrusion resistance of porous peanut shell particles.
Rotating bracket: Reinforced rotating bracket suppresses vibration caused by light, uneven peanut shell feeding.
Reducer: Precision matched reducer ensures stable power transmission during continuous granular biomass processing.
304 stainless steel dust cover: 304 stainless steel dust housing resists abrasion from fine peanut shell dust and mild ash corrosion.
Internal lifting knife: Built-in internal lifting knife breaks loose shell accumulation and prevents material bridging inside the pelletizing cavity.
Adjustable blades: Adjustable blades calibrate feed thickness specially for lightweight, porous peanut shell particles.

Unique Advantages
1.TONY pellet mill uses a 304 stainless steel cavity, significantly improving corrosion and rust resistance compared to the common 201 stainless steel used in other mill. It is resistant to moisture and acidic materials.
2.The smooth 304 stainless steel inner wall prevents material accumulation, reducing sticking and clogging. Continuous production stability far surpasses that of ordinary 201 models.
3.The entire mill is free of rust, producing clean, impurity-free finished particles with superior appearance and a higher selling price. 201 models are prone to rust shedding over long-term use.
4.The equipment is wear-resistant and impact-resistant, with a stronger structural body. It remains undeformed and weld-free even under prolonged vibration, unlike the less resilient and crack-prone 201 material.
5.Equipped with a heavy-duty reinforced transmission system, the 132KW power output is more stable, ensuring consistent power and low temperatures even under full load.
