This is a flat-die industrial pellet mill that converts biomass and agricultural waste (sawdust, straw, rice husk, corn stalks, peanut shells, etc.) into high-density fuel pellets or fertilizer granules for burning or reuse. It uses an integrated closed gearbox and a rotating press roller with a stationary flat die for continuous pelletizing.
It processes a wide range of biomass and fertilizer wastes: wood chips/sawdust, bamboo, palm, corn/cotton stalks, straw, rice husks, peanut shells, sunflower, alfalfa, paper, animal manure and many other plant or fertilizer wastes.
Available models from the specification: F200 — 7.5 kW, 80–150 kg/h, 420 kg; FD260 — 15 kW, 100–200 kg/h, 500 kg; FD300 — 22 kW, 200–300 kg/h, 800 kg; FD350 — 30 kW, 300–400 kg/h, 900 kg; FD400 — 37 kW, 400–600 kg/h, 1000 kg; FD450 — 45 kW, 600–800 kg/h, 1500 kg; FD550A — 55 kW, 700–1000 kg/h, 1800 kg; FD550B — 75–90 kW, 1000–1200 kg/h.
Flat-die pellet mills typically produce pellets in common diameters (for example 6, 8 or 10 mm). Die hole size can often be customized — confirm available die sizes with the supplier for your target pellet diameter.
Recommended moisture content is low — generally 8–15% (optimal around 10–12%) for best pellet quality and compression. Feedstock should be ground to a fine and uniform size (recommended below about 3–5 mm) to ensure smooth pressing and consistent pellets.
Yes. Materials should be shredded or milled to the recommended particle size and dried to the correct moisture range. Some materials may also require blending, pre-compaction or addition of a binder to improve pellet strength and durability.
The design is for automatic pelletizing with vertical feeding and continuous operation. Small-capacity models are suited to small factories, home users or boiler heating systems; feeding options and automation level can be adapted to your needs.
Yes. The machine can press biomass fuel pellets and also produce fertilizer granules from suitable fertilizer wastes (animal manure, plant waste and certain chemical/processed fertilizer materials), provided the feed is prepared correctly.
The rotating press roller with a stationary flat die and vertical feeding design helps to prevent fluffiness by ensuring the material is pressed firmly into the die. Proper pre-processing (moisture control, grinding, possible pre-compression) further reduces fluff and improves throughput and pellet quality.
Regular maintenance includes lubrication of bearings and gearbox per the manual schedule, periodic inspection and replacement of the die and rollers when worn, cleaning residue from the die and feed system, checking belt/bearing tension and electrical connections, and addressing any abnormal noise or vibration promptly.
Each model is driven by the listed motor power (see model specs). These are industrial three-phase motors; specific voltage and frequency options (e.g., 380V/50Hz or 400V/60Hz) should be confirmed with the supplier to match your local supply.
When properly processed, pellets are high-density, low-moisture fuel suitable for domestic and industrial pellet stoves and boilers. Good pellets burn efficiently with stable calorific output; storage in dry conditions preserves quality.
Typically suppliers provide spare parts (dies, rollers, bearings), installation guidance, operation manuals and training. Warranty terms and after-sales support vary — confirm the exact package, spare parts availability and lead times with the vendor before purchase.
Low output or poor pellet quality is usually caused by wrong moisture content, oversized feed particles, worn die/rollers, or incorrect feed rate. Overheating can be caused by insufficient lubrication or excessive load. Address these by adjusting moisture/grind size, replacing worn parts, ensuring proper lubrication and matching feed rate to machine capacity.
