The First Site Visit – Two Empty Buildings

The client called us in September 2023. He’d already leased the buildings. Sent us photos. The buildings were basic – concrete floors, steel frames, corrugated metal roofs. Building 1 (the western building) was about 1,500m². Building 2 (the eastern building) was about 2,000m². Total 3,500m². Height was 8 meters at the eaves – enough for a 5-meter tall pellet mill but tight for a large cooler.

He had one question: “Can you fit a 5t/h line into these two buildings?”

We flew a project engineer to Tema to see the site in person. The buildings were 15 meters apart. Enough space for a covered conveyor. Building 1 had good access for trucks bringing in waste wood and waste furniture. Building 2 had a large roller door for finished goods loading.

The client’s budget was $300,000 for equipment and installation. He already had the buildings leased for $2,000/month. We told him it was tight but possible.

Here’s what we designed.

Building 1 – Size Reduction (1,500m²)

We divided Building 1 into three zones.

Zone 1 – Raw Material Storage (700m²)
The south end of Building 1 became the raw material area. Waste wood and furniture arrive by truck, get unloaded with a grapple loader, and stack in piles. The client stores about 500 tons at a time – enough for 10-12 days of production.

The key constraint: no painted or treated wood. The client trained his receiving staff to reject any load with visible paint, glue, or laminate. One contaminated load can ruin an entire batch of pellets (the glue creates sticky dust that clogs the baghouse).

Zone 2 – Crushing and Grinding (800m² combined)
The north end of Building 1 has two areas:
-Chipping area) – 400m² in the northwest corner. One 200# crusher (55kW) reduces large waste wood chunks to 50-80mm pieces.
-Grinding area – 400m² in the northeast corner. Three 90# hammer mills (75kW each) in parallel, each with 6mm screens. They reduce the crushed material to sawdust-size particles.

Between the crusher and the hammer mills, we installed a magnetic separator to catch nails and screws from the furniture waste. The client pulls out about 15kg of scrap metal per week – sold to a local recycler.

The crusher and hammer mills share one dust collection system: a collection hood over each machine, feeding into a cyclone + baghouse with a 15m exhaust stack. Total airflow 10,000 m³/hr. The baghouse captures about 95% of the dust from these processes.

Zone 3 – Reserved Space (300m²)
The client wanted reserved workshop space for future expansion – maybe a second crusher or storage for a different feedstock. Currently empty, but the concrete is poured and power is roughed in.

Building 2 – Pelleting and Storage (2,000m²)

Building 2 is where the actual pellet production happens. We divided it into two zones.

Zone 1 – Pelleting Area (300m²)
The west end of Building 2 contains the pelleting area. Five 508# wood pellet mills (110kW each) arranged in a U-shape around a central conveyor. The client runs four mills at a time and keeps one as a spare for die changes and maintenance.

The mills run at 70-80% load, producing about 1.2-1.3 t/h each. Total output with four mills running: 4.8-5.2 t/h.

The pelleting process is purely physical – no binders added. The wood waste contains natural lignin. Under the pressure and heat of the pellet mill (the client’s process reaches 100-130°C at 300 tons of pressure), the lignin softens and binds the wood fibers together. The compression ratio is about 5.5:1.

Zone 2 – Finished Goods Storage (1,400m²)
The east end of Building 2 is the finished goods warehouse. Pellets cool naturally on the conveyor from the mills to the storage area – no separate cooler. The client tried a cooler in the first month but found it unnecessary because the warehouse is well-ventilated and pellets reach ambient temperature within 2 hours.

The storage area holds about 800 tons of bagged pellets. The client uses a forklift to stack pallets 4 high.

Connecting the Two Buildings
The ground conveyor between buildings wasn’t practical – vehicles needed to pass between them. We designed an overhead enclosed conveyor (6 meters high, 15 meters long) with a screw conveyor inside. Ground material from Building 1 is lifted by a bucket elevator to the overhead conveyor, then drops into Building 2. Simple, keeps material dry, and doesn’t block traffic.

Equipment List – What Shipped from Qingdao

Equipment price (EXW Qingdao port): $218,000 USD

The client bought the grapple loaders, forklifts, and wheel loaders locally in Ghana – cheaper than importing, and local service is available.

Shipping: Four 40-foot containers. Departed Qingdao November 10, 2023. Arrived Tema Port, Ghana on December 15, 2023. Sea freight: $7,200 USD. Customs clearance and inland trucking added $2,500 USD.

Process Flow – From Waste Wood to Pellets

Here’s how the 5t/h wood pellet plant construction project in Ghana actually runs, step by step.

Step 1 – Raw material receiving
Trucks arrive at Building 1’s south entrance. Workers inspect each load for painted or treated wood. Rejection rate is about 2-3% – mostly furniture with visible paint or laminate. Rejected loads go back to the supplier.

Step 2 – Crushing
The grapple loader feeds waste wood into the 200# crusher. Output size: 50-80mm chunks. This step runs continuously during production hours.

Step 3 – Grinding
Crushed material drops onto a belt conveyor feeding the three 90# hammer mills. The mills run in parallel, each taking about 1.7 t/h. Output size: 95% passing through a 6mm screen.

Step 4 – Magnetic separation
Before the ground material leaves Building 1, it passes over a magnetic head pulley. This catches nails, screws, and staples. The client empties the magnet bin weekly.

Step 5 – Transfer to Building 2
The ground material drops into a bucket elevator, lifts to the overhead screw conveyor (6 meters high), crosses between buildings, and drops into a holding bin in Building 2. The holding bin holds about 10 tons – enough for 2 hours of pellet mill operation.

Step 6 – Pelleting
Material from the holding bin feeds into the five wood pellet extruder machines. The client runs four mills at a time. Each mill produces about 1.2-1.3 t/h. Die size: 8mm for industrial boilers.

Step 7 – Cooling and storage
Pellets drop onto a long belt conveyor that runs the length of Building 2. By the time they reach the storage area (about 60 meters), they’ve cooled from 100°C to 35-40°C. No forced-air cooler needed.

Step 8 – Bagging and shipping
The client uses a manual bagging station – two workers filling 25kg bags, another worker stacking on pallets. He sells about 70% of output in bags, 30% in bulk to a nearby cement plant.

What the Client Learned (The Hard Way)

The first month of operation (January 2024) was rough. Here are three problems that came up.

Problem 1 – The hammer mills kept jamming.
The waste furniture had too many long, stringy pieces. They wrapped around the hammer mill rotors and blinded the screens.

Fix: We added a pre-shredder before the crusher (the client bought a used unit locally for $3,000). The shredder cuts the furniture into 100-150mm pieces before crushing. No more jams.

Problem 2 – Dust collection wasn’t balanced.
The Building 1 dust collector was oversized for the crusher but undersized for the three hammer mills. The hammer mills would overload the filter, causing pressure drop alarms.

Fix: We reconfigured the ductwork to give each hammer mill its own pickup point with a dedicated damper. Now the client can balance the airflow. Took two days.

Problem 3 – Pellet quality was inconsistent.
The first batch of pellets had a durability index (PDI) of only 88% – too low for the cement plant customer. The pellets were cracking in transit.

Fix: The client was running the wood pellet presses too cold. He increased the feed rate slightly (more material in the die = more friction = higher temperature) and switched to a longer die (compression ratio 1:6 instead of 1:5.5). PDI improved to 94%.

The Ghanaian Market for Wood Pellets

Ghana is an interesting market for biomass pellets. The country has:

• A growing industrial sector (cement, textiles, food processing) looking for alternatives to imported coal and diesel
• Abundant waste wood from furniture manufacturing and logging operations
• Government incentives for renewable energy under the Renewable Energy Act (2011)

But there’s a catch. Most Ghanaian factories are used to cheap, unreliable fuel. Convincing them to pay $130/ton for consistent, high-quality pellets takes time.

The client’s strategy: start with one anchor customer. He signed a 12-month contract with a cement plant in Tema for 500 tons/month at $125/ton. That covers his fixed costs. The remaining 500 tons/month he sells to smaller customers at $135-140/ton. As demand grows, he’ll add a second shift and double his output without adding equipment.

The cement plant customer switched from imported coal ($180/ton delivered) to the client’s pellets. They save $55/ton on fuel and reduce their emissions. Everyone wins.

Thinking About a Larger-Scale Project?

If you’re looking at a 5t/h wood pellet plant construction project in Ghana – or anywhere in West Africa – here’s what we’ve learned:

• Two-building layouts work if you plan the material flow. The overhead conveyor was the right solution. Don’t try to move material between buildings at ground level – you’ll block truck access.
• Dust collection is not optional. The Ghana EPA enforces emissions limits. Budget for it from the start.
• Start with one anchor customer. The cement plant contract gave the client predictable revenue while he built his retail customer base.
• Buy local for loaders and forklifts. The client saved about 40% on shipping and customs by buying his material handling equipment in Ghana.

The client in Tema is already planning a second shift. Same equipment, double the output. He figures he can sell 2,000 tons/month within 12 months.

If you have a building (or two) and a source of waste wood, send us a message. We’ll tell you what’s realistic for your site.
