0086-138 3838 9622Wood Husk Crop Pellet Production Line in Greece
RICHI MACHINERY
Overview
This 4t/h wood husk crop pellet production line in Greece is designed to convert mixed agricultural and forestry residues into standardized fuel pellets. The plant runs 300 days per year, with 10 workers, using a compact but complete production setup including crushing, drying, pelletizing, and packaging.
Unlike some projects that rely on single raw materials, this pelletizing line handles a blended biomass structure—wood waste, crop residues, and husk materials. That changes everything, from drying design to pellet stability.
The client didn’t ask for “a pellet production line” at the beginning.
What they asked was:
“We have different materials every week. Can your system handle that without constant adjustments?”
That question shaped the whole design.
So this biomass pelletizing plant in Greece was built with:
- flexible feeding
- stable drying control
- dual pellet mills for load balancing

What this project looks like when you first walk into the plant
The first impression of this 4t/h wood husk crop pellet production line in Greece is not the machines—it’s the raw material yard.
Stacks of straw, rice husk, bark, and sawdust are piled in sections, not perfectly organized, but clearly planned. You can tell this is not a single-material plant. It’s built around flexibility.
This project delivers 20,000 tons per year of biomass pellets, running on a two-shift schedule. The client didn’t go for an oversized system. Instead, they chose a steady 4t/h biomass pellet plant in Greece that matches local feedstock supply and labor conditions.

Project background
The biomass pellet project is located near Larissa, a region where agricultural residues are abundant.
The client operates a mid-sized biomass collection business:
- crop straw from nearby farms
- rice husk from milling facilities
- wood residues from small sawmills
Before this Wood Husk Crop Pellet Production Line in Greece project, most of these materials were either burned in the field or sold cheaply.
Initial inquiry came in January 2024.
Contract signed in April 2024.
The client’s goal was simple but practical:
- stabilize income from waste biomass
- reduce seasonal price fluctuations
- supply local heating fuel market

Facility layout
The site is not large, but it’s well utilized.
| Section | Area | Function |
|---|---|---|
| Total land | 4400 m² | Entire plant |
| Production workshop | 2200 m² | Crushing, drying, pelletizing |
| Raw material yard | 2000 m² | Storage of mixed biomass |
| Office area | 200 m² | Administration |
One thing we adjusted early:
The raw material yard needed more separation zones. Mixed materials behave differently in drying.

Raw materials
In Greece, biomass supply is seasonal and diverse. The client’s material mix looks like this:
| Material Type | Annual Volume (t) | Moisture Range | Source |
|---|---|---|---|
| Sawdust | 12,000 | 8–12% | Wood workshops |
| Crop straw | 8,000 | 15–25% | Local farms |
| Rice husk | 5,000 | 10–18% | Rice mills |
| Bark | 3,000 | 20–30% | Logging residues |
| Tobacco stems | 2,000 | 18–28% | Agricultural waste |
Total raw material handled annually exceeds 30,000 tons.
Some batches came in wetter than expected. First week of commissioning, we had to slow down the biomass dryer slightly—otherwise pellets cracked.

Main equipment configuration
The client already understood basic pellet production, so we focused on reliability rather than over-configuration.
Crushing section
| Equipment | Quantity |
|---|---|
| Feeding inlet | 1 |
| Multifunction crusher | 1 |
| Airlock | 1 |
| Fan | 1 |
| Bag filter | 1 |
Drying section
| Equipment | Quantity |
|---|---|
| Biomass hot air furnace | 1 |
| Belt conveyor | 1 |
| Airlock feeder | 1 |
| Rotary dryer | 1 |
| Discharge airlock | 1 |
| Fan | 1 |
| Wet scrubber (water film dust collector) | 1 |
| Conveyor | 1 |
| Raw material bin | 1 |
The decision to use a biomass furnace instead of fossil fuel saved long-term cost. The client burns low-grade residues for heat.
Pelletizing section
| Equipment | Quantity |
|---|---|
| Feeder | 1 |
| Ring die biomass pellet mills | 2 |
| Bag filter | 1 |
| Fan | 1 |
| Conveyor | 1 |
| Airlock | 1 |
The two biomass granulators give flexibility. If one stops, production doesn’t drop to zero.
Cooling & packaging
| Equipment | Quantity |
|---|---|
| Cooler & screener combo | 1 |
| Vibrating unit | 1 |
| Cyclone separator | 1 |
| Bag filter | 1 |
| Conveyor | 1 |
| Finished product bin | 1 |
| Packing machine | 1 |

Process flow
The 4t/h wood husk crop pellet production line in Greece runs through these steps:
- Chipping / Pre-sizing
Larger materials reduced before crushing. - Crushing
Mixed biomass processed into uniform particles.
Dust generated—handled by bag filters. - Drying
- Biomass furnace provides heat
- Moisture reduced to ~10–12%
- Mixing (natural blending)
No separate mixer—blending happens during conveying. - Pelletizing
- Double ring die biomass pellet press system
- One-step compression
- No carbonization
- Cooling
Fresh pellets are hot and soft. Cooling stabilizes them. - Screening & packaging
Fine powder recycled.

Environmental measures
The client needed compliance with local environmental inspections.
- Dust control:
- Bag filters across key points
- Water film dust collector in drying
- Wastewater:
- Small sedimentation tank (5 m³)
- Septic tank (10 m³)
- Solid waste:
- Reused internally where possible
- Noise:
- Equipment isolation + structural damping

Investment and cost control
The client was cautious about investment.
- Equipment cost: ~$210,000
- Total project cost: ~$380,000
Given EU labor costs, this is considered moderate for a 4t/h biomass pellet plant in Greece.

Logistics
All equipment was shipped from Qingdao Port to Port of Piraeus.
Delivery took about 32 days.

What actually happened during commissioning
Not everything went perfectly.
- First batch: moisture uneven
- Second batch: pellet density too low
- Third batch: stable output
After adjusting feed rate and drying temperature, the line stabilized.
That’s pretty typical for mixed biomass projects.
RICHI MACHINERY
A few things the client cared about
- Can different materials be used together? → Yes, but moisture must be controlled
- Is drying always necessary? → For mixed biomass, almost always
- How many operators are needed? → Around 10 is enough

Market situation in Greece
Pellet demand in Greece is steady, especially in:
- residential heating
- small industrial boilers
Local supply is still not fully stable, especially for blended biomass pellets.
That creates space for plants like this.
This 4t/h wood husk crop pellet production line in Greece works not because it is large, but because it matches:
- local raw materials
- realistic labor
- manageable investment
If you’re planning something similar, the first thing to figure out isn’t the machine—it’s your raw material consistency. Everything else follows from that.
