Wood Pellet Manufacturing Facility in Romania

RICHI MACHINERY

The First Call: A Realistic Start

We got an inquiry in late May 2024. Not one of those polished, multi-page RFQs with every detail pre-defined. It was shorter. The subject line just said: “2t/h wood pellet manufacturing facility – need realistic setup.”

The guy on the other end—let’s call him the project lead—had done some homework. He knew the local market. He knew what biomass was available. But he was stuck on one thing: inconsistent moisture content in Romanian waste wood.

He’d seen too many wood pellet production lines in Hungary and Serbia fail within six months because they copied a German or Austrian design. Those designs assume perfect, kiln-dried sawdust. That’s not what he had.

He had access to:

• Furniture factory offcuts (10-14% MC)
• Construction waste wood (often 18-22% MC, sometimes higher after rain)
• Some pallet shredding leftovers

His big question wasn’t “how many horsepower?” It was: “How do you engineer a 2t/h wood pellet manufacturing facility that won’t choke when a load of slightly damp trim shows up?”

That’s the kind of conversation we actually like. Not a spec sheet fight. A real problem.

Raw Materials & Consumption

The feedstock mix is straightforward but requires careful inbound management. Here’s what the client secured contracts for before signing with us:

The total input-to-output ratio is about 1.0004:1 by weight, accounting for moisture loss and dust collection. The client actually overbought slightly on purpose—5002 tons input for 5000 tons output—to have buffer for fine particle loss and the occasional rejected bale.

No binders or additives. The natural lignin in the wood does the binding work during the pelleting step. That’s one less thing to buy and store.

The Custom Process Flow

We didn’t just hand over a standard P&ID. We sat down and walked through each step with their local operations guy. Here’s what the actual 2t/h wood pellet manufacturing facility flow looks like, with the tweaks we made specifically for this region:

Step 1 – Reception and Manual Pre-Sorting
Before anything hits the metal, a two-person team pulls out obvious contaminants: stones, metal brackets, plastic wrapping, and the occasional piece of painted wood that shouldn’t go into clean biomass. They run a 6-hour shift, not continuous. The rest of the time, material feeds from the storage pile.

Step 2 – Magnetic Separation (Overbelt Magnet)
We spec’d an overbelt magnetic separator, not just a drum magnet. Why? Because Romanian waste wood sometimes has long pieces of rebar or steel strapping that can wrap around a drum and cause a shutdown. The overbelt pulls it off from above before it reaches the crusher.

Step 3 – Primary Crushing (Slow-Speed Shredder)
The client initially asked about a high-speed hammer mill. We talked them out of it. High-speed mills hate variable moisture. They get screen blinding and generate too much fine dust that clumps. Instead, we used a low-speed (150 RPM) twin-shaft shredder with interchangeable screens. First pass takes material down to 30-50mm chips.

Step 4 – Intermediate Storage and Blending (Live Bottom Bin)
This is the part that makes the 2t/h wood pellet manufacturing plant actually work. A live bottom bin with variable-speed discharge allows them to blend drier furniture waste (14% MC) with wetter construction waste (20% MC) before final milling. The bin has internal sweep augers to prevent bridging—a common problem with fibrous wood that’s slightly compressed.

Step 5 – Fine Grinding (Hammer Mill with Reversible Hammers)
Now we do use a hammer mill, but only after the moisture is blended down to <16% average. We chose a 132kW unit with hardened, reversible hammers. The client can flip hammers every 150 hours instead of replacing them. Screen size: 6mm for biomass pellet standard.

Step 6 – Pelleting (One Main Pellet Mill, No Standby)
The heart of the 2t/h wood pellet manufacturing facility is a single ring-die wood pellet mill. Model: RICHI 508. Die hole diameter: 8mm for residential-grade heating pellets. We designed it for 2-2.5 t/h sustained output, not maxed-out nameplate capacity. The motor is 200kW, running at 80-85% load during normal operation.

No external heating. Friction alone raises the wood temperature to 90-110°C, enough to soften lignin naturally.

Step 7 – Cooling and Screening (Counterflow Cooler + Scalping Screen)
Straight out of the die, pellets are soft and hot (~80°C). They go into a counterflow air cooler for 15-20 minutes. Then a double-deck screener removes fines (which get cycled back to the pellet mill inlet).

Step 8 – Bagging and Bulk Loading
The client chose a mix: 15kg retail bags (for local home heating market) and bulk truck loading for industrial customers (brick factories, greenhouses). Two bagging spouts, one manual palletizer.

Plant Layout and Building Constraints

The client leased an existing industrial building in an organized park near Arad. Not purpose-built for pellets, so we had to adapt.

• Total footprint used: 2,040 m²
• Main production hall: 1,400 m² (one floor)
• Raw material storage: 200 m² (separate bay)
• Finished goods storage: integrated within main hall
• General solid waste storage: 20 m² (dust collection bags, metal scrap)
• Office + break area: 400 m² over three floors (ground: showroom/rest, first: offices + small kitchen, second: rest area for shift workers)

The building height was 8 meters at the eaves—tight but workable. We had to put the cooler on a mezzanine to gravity-feed into the screener. The pellet mill sits on a reinforced concrete base (vibration was a concern; the neighbor unit does light fabrication).

No external silos. The client decided against them due to local permitting delays. Instead, they use the 200 m² storage bay for loose wood chips and run a daily shift to keep the blending bin fed.

Utilities and Operating Schedule

Power: 400V, 50Hz grid supply. Total connected load is 520kW, but actual running draw is around 350-380kW at full production. The local grid in Arad industrial zone is stable; no voltage sags reported so far.

Water: Only for staff. No process water. Municipal supply, 20 people, 50L/person/day = 300 m³/year. Sewage to municipal treatment after a simple septic tank.

Labor: 8 people total, not 20. The original plan overestimated. Actual crew:

• 2 material handlers (loader + forklift)
• 2 operators (one on pellet mill, one on hammer mill/cooler)
• 1 quality/bagging
• 1 maintenance/electrical
• 1 site manager
• 1 cleaner/relief

Shift: 8 hours/day, 300 days/year = 2,400 operating hours.

The Real Headache We Solved (And Why It Matters)

About three weeks after commissioning, the client called. Pellets were coming out with surface cracks and high fines. Output had dropped to 1.2 t/h.

We flew a technician from our regional support hub in Budapest. First thing he checked: moisture at the pellet mill inlet. It was 19%. The construction waste pile had gotten rained on for two days, and the blending bin wasn’t being fed proportionally because the loader operator was rushing.

The fix wasn’t new hardware. It was a simple blending protocol:

1. Every morning, test moisture of each feedstock pile with a handheld meter.
2. Calculate blend ratio to hit 14-15% target.
3. Set live bin discharge speeds accordingly.

We also added a small moisture meter display at the operator station. Cost: $400. The client later added a second blending bin so they could pre-mix a shift’s worth of material at the correct ratio.

That’s the difference between selling a box and engineering a solution. The 2t/h wood pellet manufacturing facility now runs at 2.1-2.3 t/h consistently, even during Romania’s wet autumn months.

Environmental and Operational Notes

No forced-draft dryer means no combustion permit hassles. That was a deliberate choice. In Arad County, getting an environmental permit for a biomass dryer adds 4-6 months and $15,000 in fees.

Dust control: Two baghouse filters. One for the hammer mill, one for the pellet mill. Both discharge into sealed containers. Collected dust gets re-pelleted (it’s just fine wood, after all).

Noise: The pellet mill runs at about 95 dB at 1 meter. Building is concrete sandwich panels. At the property line (30 meters away), it’s under 65 dB. Compliant with Romanian norms.

Waste streams:

• Ferrous metal: sold to scrap dealer (about 15 tons/year)
• Dust: re-used (zero waste)
• Rejected pellets: crushed and re-pelleted

Why Romania Right Now for Wood Pellets?

The EU’s push away from Russian natural gas has created a real opportunity in Central and Eastern Europe. Romania specifically:

• Has its own natural gas, but prices for households still doubled between 2021 and 2023. Pellets are now cost-competitive.
• Subsidy programs for replacing old coal/wood stoves with modern pellet boilers (through AFM – Administration of Environmental Fund).
• Surplus waste wood from furniture manufacturing (the region around Reghin and Satu Mare produces thousands of tons annually).
• Trucking distance to Hungary and Serbia is short, so export is viable if local demand softens.

The client’s 2t/h wood pellet manufacturing facility produces about 5,000 tons annually. At current wholesale prices in Romania (€180-210/ton), that’s roughly €900,000 to €1.05 million in annual revenue. Even after paying for raw material (€25-35/ton delivered), electricity, labor, and maintenance, the payback period is comfortably under 24 months.

And that’s at conservative prices. During the peak winter of 2022, retail bagged pellets hit €450/ton in some Romanian cities.

What We Actually Provide

A customer doesn’t just buy a pellet mill. They buy a production plan.

For this wood pellet plant construction project, we delivered:

• Process design (layout, material flow, moisture management strategy)
• Equipment selection (right machine for Romanian waste wood, not a German spec sheet)
• Installation supervision (our guy slept in Arad for 12 nights)
• Operator training (two days on blending ratios, die gap settings, hammer reversal schedule)
• Spare parts kit (one extra die, two sets of hammers, belts, bearings – enough for 2,000 operating hours)

We didn’t just email a manual. We did a WhatsApp video call at 9 PM on a Saturday when the automatic lubricator fault code popped up. That’s the actual service.

A Few Things We’d Do Differently

If we did this biomass pellet project again:

1. Add a second blending bin from the start. The single bin works, but dual bins would allow continuous operation while refilling.
2. Spec a slightly larger cooler. The current unit handles 2 t/h fine, but during summer (30°C ambient), pellets come out at 45°C instead of 35°C. Still within spec, but higher than ideal for bagging.
3. Convince the client to buy a moisture meter with data logging. They’re using a $150 handheld now. It’s fine, but a mounted near-IR meter at the pellet mill inlet would automate the blending.

But the client was on a budget. And the 2t/h wood pellet manufacturing facility works. It makes money. That’s what counts.

Thinking About Your Own Project?

If you’re looking at biomass pellets—whether from wood, agricultural residues, or even sunflower husks—the questions aren’t just about “which pellet mill brand.” The real questions are:

• What’s your actual feedstock moisture range, week to week?
• Do you have covered storage, or will rain be a problem?
• Who’s your local electrical contractor for the 400V connection?
• What’s your exit plan for fines and rejected pellets?

We’ve done 2t/h wood pellet manufacturing facilities in Serbia, Bulgaria, Poland, and now Romania. Each one needed a slightly different hammer mill screen, a different blending strategy, a different cooler sizing.

We don’t guess. We ask the messy questions first. Then we build.
