how to set up wood pellet mill plant ?
+
Your funds and budget are the first things to consider in your wood pellet mill plant construction. Your budget tends to tell the scale of the wood pellet plant regarding large size or small scale. In case you do not have sufficient funds, then consider lowering your capacity.
Consequently, you can get even lower some relatively unimportant equipment. However, in cutting cost, it is never advisable to substitute the necessary equipment with low price and low-quality ones. You might end up regretting the move.
Your workshop is another thing that you need to consider in wood pellet mill line construction. In fact, the funds available to you will tend to determine your workshop size in that the higher the resources, the bigger the workshop you can build.
Again, consider having your wood pellet plan design near your raw material to ensure that you cut the cost of raw material transportation. Consequently, if you have a workshop, determine its height, width, and length. Consider then designing your wood pellets depending on your workshop size to ensure it is enough to lace the equipment.
Please provide us with wood pellet mill plant project information as much as possible:
- For a complete wood pellet mill plant project: the raw material availability, the required production capacity, the process technology, your budgetary and financing status, the estimated starting time, etc.
- For single wood pellet mill machine: the model, the capacity, your budget information, other requirements, etc.
- For spare parts: size and dimensions, material and weight, and your drawings with details, you can send the drawing to enquiry@richipelletmachine.com.

What are the uses of pellets processed by wood pellet mill??
+
Our wood pellet mills produce versatile biomass pellets for:
1. High-Value Industrial Uses
- Foundry additives (replacing sand in metal casting)
- Rubber/plastic filler materials (5-15% cost reduction)
2. Premium Animal Solutions
- Dust-controlled horse bedding (€0.45/kg in EU markets)
- Absorbent pellets for poultry/livestock operations
3. Specialized Consumer Products
- Cat litter (expands 3x when wet)
- BBQ smoking pellets (hardwood blends for chefs)
4. Agricultural Enhancements
- Mushroom cultivation substrates
- Slow-release fertilizer carriers
02
What are the raw materials suitable for wood pellet mill??
+
Our wood pellet mills process 50+ biomass types efficiently:
1. Primary Wood Materials
- Softwoods (Pine, Spruce, Fir)
- Hardwoods (Oak, Maple, Beech)
- Mixed sawdust (30% moisture max)
2. Agricultural Byproducts
- Rice husks (40-60% yield after processing)
- Corn stalks (requires pre-crushing <5mm)
- Coconut shells (special wear-resistant dies needed)
3. Industrial Waste Streams
- MDF/Plywood residues (binder adjustment required)
- Paper mill sludge (drying pretreatment essential)
Key Equipment Adaptations:
• Variable die thickness (6-12mm) for different densities

• Optional pre-drying systems
03
Why is the ring die wood pellet mill the most widely used equipment at present??
+
After decades of engineering improvements and real-world testing across hundreds of installations, ring die wood pellet mills have proven to be the superior choice for serious biomass producers. Here’s why:
1. Unmatched Production Capacity & Efficiency
Unlike flat die wood pellet mills that operate in batches, our ring die systems feature continuous 360-degree compression for non-stop processing. The rotating die design maintains consistent throughput whether you’re running 8-hour shifts or 24/7 operations. Our SRD series achieves 3-30+ TPH depending on model – that’s enough to supply entire district heating plants or export-scale operations.
2. Superior Pellet Quality That Commands Premium Prices
The radial compression of ring dies creates more uniform density (650kg/m³ ±5%) and exceptional durability (95%+ by ISO 17831). This means:
- Fewer fines during transport (under 3% vs 8-12% with flat die)
- Consistent combustion performance for energy customers
- Ability to meet strict export market specifications
3. Lower Operating Costs That Boost ROI
While the initial investment is higher, ring die mills save money long-term:
- Energy efficiency: Our gear-drive systems use 30% less kWh/ton
- Die longevity: Special alloy dies last 5,000+ hours vs 1,200-2,000 for flat die
- Labor savings: Automated lubrication and remote monitoring reduce staffing needs
4. Unparalleled Material Flexibility
From dusty sawmill residues to tough agricultural waste, our mills handle what others can’t:
- Mixed biomass blends stay homogeneous during processing
- Adjustable compression ratios (6:1 to 15:1) accommodate everything from pine to rice husks
- Optional pre-conditioning systems optimize moisture for each material
Why Our Ring Die Mills Outperform Competitors
✔ Quick-Change Die System – Swap dies in 30 minutes vs industry-standard 2 hours
✔ Dual-Layer Alloy Dies – Hardened outer surface with tough inner core lasts 3x longer
✔ Smart Pressure Monitoring – Real-time adjustments ensure perfect pellet formation
✔ Modular Design – Easily upgrade from 5TPH to 15TPH as your business grows
This isn’t just equipment – it’s your competitive edge in the global biomass market. Let’s discuss how to maximize your production potential.
