Straw Pellet Machine – Biomass Pelletizing Equipment for Agricultural & Forestry Residues
1. Product Overview
The SYLH Series Straw Pellet Mill is a high-efficiency, energy-saving biomass pelletizing system specifically engineered for processing agricultural and forestry residues into dense, high-calorific-value biomass pellets. By transforming low-bulk-density waste materials—such as straw, wood chips, and nut shells—into compact fuel pellets, this equipment plays a vital role in renewable energy production, waste resource utilization, and sustainable agricultural development.
With a standard capacity range of 0.3 to 3 tons per hour and finished pellet sizes adjustable from 6 mm to 12 mm, the SYLH Series accommodates diverse production requirements—from small farm-based operations to commercial biomass fuel manufacturing facilities. Its robust construction, intelligent control systems, and low energy consumption make it the ideal choice for turning agricultural and forestry waste into valuable energy resources.
2. Applicable Raw Materials
The SYLH Series is compatible with a wide range of dry, fine biomass raw materials, offering exceptional versatility for diverse processing needs:
| Category | Raw Materials |
|---|---|
| Wood Residues | Wood chips, sawdust, wood shavings |
| Crop Residues | Wheat straw, rice straw, cotton stalk, corn stover |
| Husks & Shells | Rice husk, palm shell, peanut shell, sunflower husk |
| Industrial Residues | Bagasse (sugarcane residue), olive residue, fruit pomace |
| Other Biomass | Bamboo powder, grass, alfalfa, municipal green waste |
This broad material compatibility ensures that operators can source locally available feedstocks, reducing transportation costs and securing stable supply chains regardless of seasonal or regional variations.
3. Core Product Features
1. Efficient Transmission & Stable Power Output
The main transmission system incorporates a high-precision gearbox, delivering superior transmission efficiency with minimal power loss. This robust design ensures long-term continuous stable operation with low failure rates, even when processing challenging, high-fiber materials that demand greater torque and compression force.
2. Intelligent Feeding & Comprehensive Safety Protection
The machine adopts a frequency-conversion (electromagnetic speed regulation) feeding system with precise speed control and uniform material flow. Integrated overload protection and a high-strength magnetic safety device effectively prevent equipment damage from foreign objects and operational surges, ensuring comprehensive production safety.
3. Superior Performance & Easy Maintenance
Featuring high output, low noise, and low energy consumption, the SZLH Series is designed for operational efficiency. Its thoughtful structural layout simplifies routine cleaning, inspection, and maintenance, significantly reducing labor costs and operational downtime.
4. Premium Components & Long-Term Durability
Core bearings and critical standard parts are sourced from internationally recognized brands, offering high precision, excellent wear resistance, and extended service life. This commitment to quality ensures the stability and durability of the entire machine, even under demanding production schedules.
5. Flexible Ring Die Options for Wide Adaptability
The equipment is supplied with ring dies featuring multiple aperture sizes (6–12 mm) and varying thicknesses. Users can select the optimal die configuration based on raw material characteristics, production requirements, and finished product specifications, ensuring optimal pellet quality across diverse applications.
