Small Flat Die Pellet Machine
Product Overview
The Small Flat Die Pellet Machine is a compact pelletizing unit engineered for small-scale biomass and animal feed processing. Compared to industrial ring die systems, this machine utilizes a direct-drive flat die mechanism, offering a smaller footprint, lower equipment investment, and straightforward mechanical upkeep. It is suited for wood processing workshops, small farms, and distributed fuel production, converting loose organic waste into standardized solid pellets.
Key Performance Advantages
Compact Footprint and Flexible Installation
• Dimensions & Space: Designed with a vertical layout that requires less than 2 square meters of floor space, eliminating the need for dedicated industrial buildings.
• Mobility: Can be paired with a small utility trailer or configured with wheels for relocation between agricultural sites or timber yards.
• Investment Profile: Avoids complex civil construction, heavy concrete foundations, or specialized boiler rooms, lowering initial capital expenditure.
Direct-Drive Transmission and Energy Efficiency
• Direct Power Transfer: Utilizes a direct-coupled or heavy-duty gearbox-driven system to minimize mechanical power loss compared with multi-stage belt drives.
• Capacity Range: Delivers actual outputs ranging from 50 kg/h to 800 kg/h across our model lineup (e.g., KL-120, KL-200, KL-300, KL-400), governed by motor horsepower, die compression ratio, and raw material density.
Alloy Steel Die and Roller Assembly
• Material Composition: Both the flat die and pressure rollers are machined from structural alloy steel (such as 40Cr).
• Thermal Treatment: Subject to vacuum quenching and carburizing heat treatments, achieving a working surface hardness of HRC 55–60 to withstand abrasive wear from silica in biomass.
• Standard Specifications: Precision-drilled die holes with uniform compression ratios, offering standard hole diameters of 6 mm, 8 mm, 10 mm, and 12 mm (custom compression ratios available upon request for specific materials like hardwood vs. soft straw).
Broad Raw Material Adaptability
• Biomass Processing: Handles softwoods (pine, fir), hardwoods (oak, eucalyptus after fine crushing), agricultural straws (wheat, rice, corn stalks), and grass fibers.
• Feed Formulation: Compresses mixed formulations including corn meal, wheat bran, alfalfa meal, and soybean meal for poultry, livestock, and aquaculture.
• Preparation Requirements: Materials must be pre-conditioned to a particle size under 5 mm and a controlled moisture content of 10% to 15% prior to entering the pellet chamber.
Simplified Mechanical Maintenance
• Roller Adjustment: Features an accessible external adjustment bolt system to regulate the clearance gap between the flat die and rollers.
• Die Replacement: The flat die can be hoisted or unbolted vertically using standard workshop tools, reducing component changeover time to under 45 minutes.
• Lubrication Points: Equipped with grease nipples positioned externally for routine bearing maintenance without dismantling the main housing.
• Global Support & Spare Parts: We stock modular replacement dies, rollers, and bearings for global shipping, supported by comprehensive replacement guides and video tutorials.

Quality Control & Factory Testing
Raw Material Verification
Chemical composition and ultrasonic testing are performed on steel billets to check for internal micro-cracks before machining.
Precision Machining
Die hole diameters and concentricity tolerances are verified using digital gauge instruments to ensure consistent extrusion pressure.
Factory Run Test
Every unit undergoes a 2-hour dry-run and simulated load test at the factory to monitor gearbox temperature rise, motor load stability, and noise levels before packaging.
FAQ
Q: What determines the actual hourly output of the machine?
A: Output is determined by the motor horsepower, the thickness and compression ratio of the flat die, the bulk density of the raw material, and the moisture level. Hardwood sawdust generally yields lower hourly output compared to softer agricultural straws due to higher required compression force.
Q: How do I prevent blockages (jamming) inside the die holes?
A: Blockages typically occur if the raw material moisture exceeds 18% or if oversized particles (>6 mm) enter the chamber. Ensure materials are pre-screened through a hammer mill screen and dried to 10%–15% moisture. At the end of a production run, run oil-mixed feed or oily residue through the die to fill the holes, preventing residual biomass from hardening inside the channels as it cools.
Q: What is the expected service life of the flat die and rollers?
A: Service life is measured in total metric tons processed rather than calendar time. A standard alloy steel die typically processes between 800 to 1,500 tons of biomass material, depending on the silica content of the feedstock (e.g., rice husk causes faster abrasion than clean pine sawdust).
Q: Can a single machine process both animal feed and wood fuel pellets?
A: Yes, but the machine requires different die compression ratios. Wood pellets require a higher compression ratio (longer compression channel) to bind lignin naturally under high pressure and heat, whereas feed pellets require a lower compression ratio to prevent excessive gelatinization and nutrient degradation. Swapping the die takes approximately 30 to 45 minutes.
