Industrial Wood Bamboo Pellet Plant Setup in Cambodia

RICHI MACHINERY

Project Overview

This 20t/h industrial wood bamboo pellet manufacturing factory in Cambodia is a single-line pelletizing system installed inside an existing steel-structure workshop (approx. 5,200 m², 12m height). The plant integrates crushing, grinding, drying, pelletizing, cooling, and packing into one continuous flow.

Another way to describe it — this is not just a pellet machine setup. It is a complete biomass pellet plant with dust control, storage logic, and energy reuse designed together. The client didn’t want separate machines; they wanted a system that actually runs.

Who Is the Client & Why This Project Started

The client is a medium-scale wood processing and bamboo supply operator in Cambodia. They were already dealing with:

• Large volumes of sawdust and wood offcuts
• Seasonal surplus of bamboo residues
• Increasing disposal costs

At the same time, Cambodia has been pushing industrial fuel alternatives due to rising fossil fuel costs. Biomass pellets started getting attention, especially for:

• Brick factories
• Garment factory boilers
• Food processing steam systems

The client didn’t jump into pellets blindly. Their concerns were very practical:

• Moisture too high (45–50%)
• Raw materials not uniform
• No experience with pelletizing
• Worried about dust and fire risk

That’s where we stepped in—not just selling equipment, but building the process logic from scratch.

Raw Materials Situation

In Cambodia, raw materials are not “perfectly prepared.” They come mixed, wet, and inconsistent. So the design had to adapt.

Main Raw Materials

A small detail many overlook:
Bamboo behaves differently from wood during pelletizing. It has higher silica content and slightly different fiber bonding. That affected die selection and compression ratio.

What the Client Wanted

During early discussions, the client kept repeating a few things:

• “We don’t want frequent shutdowns.”
• “Dust must be controlled. We had issues before.”
• “Drying cost should not explode.”
• “We prefer fewer operators.”

So instead of just matching capacity, we focused on:

• Stable feeding
• Controlled moisture reduction
• Closed conveying
• Simple layout

Final Plant Layout

The factory was already built, so we had to fit the process into the space, not redesign the building.

• Total area: 5211 m²
• Structure: steel frame, semi-enclosed
• Height: ~12.3 m

Layout Logic (Left vs Right Flow)

• Left side (process line):
  crushing → grinding → drying → screening
• Right side (pelletizing & packing):
  Biomass pellet mills → storage → packing
• Raw material area: east side
• Finished goods: multiple corners (fast dispatch design)

This layout reduced internal transport distance. Forklift movement became simpler.

Equipment Configuration

No need to complicate things with model codes here. What matters is function and matching.

A small note from our engineer on-site:
The first few test runs had uneven moisture distribution. Some batches were slightly over-dried, others not enough. After adjusting dryer airflow and feed rate, things stabilized.

Process Flow

Instead of a textbook diagram, here’s how it runs in reality:

1. Manual Sorting
   Workers remove plastics, metals, random debris. This step matters more than people think.
2. Primary Crushing
   Wood chunks and bamboo are reduced to 5–8 cm pieces.
3. Screening Loop
   Oversized materials go back. This avoids overloading the hammer mill.
4. Fine Grinding
   Everything goes to uniform small particles.
5. Drying (Key Step)
   • Temperature: ~80–90°C
   • Time: 5–10 minutes
   • Moisture reduced to ~15%
   Heat comes from burning part of the pellets produced.
6. Pelletizing
   Compression through ring die → pellets formed (~8.5mm diameter)
7. Screening Again
   Broken pellets recycled
8. Cooling (Natural in silo)
   2–3 hours airflow cooling
9. Packing
   25 kg bags, ready for transport

Utilities & Consumption

Environmental Handling

We adapted to local compliance:

• Dust → bag filters + cyclone systems
• Enclosed conveyors → less airborne particles
• Semi-closed workshop → airflow control
• Noise → vibration bases + building insulation

The client was particularly sensitive about dust because of previous complaints from nearby factories.

Investment & Cost Overview

For a 20t/h biomass pelletizing plant, this is considered a moderate investment—not aggressive, but realistic for the region.

A Few Things That Didn’t Go Perfect

• Initial dust leakage at one transfer point → fixed by sealing upgrade
• Dryer tuning took about a week
• Bamboo ratio adjustment needed trial runs

That’s normal for a plant like this. Anyone who says pellet production works perfectly from day one… probably hasn’t run one.

Market Situation in Cambodia

Biomass pellets are not yet “overcrowded” in Cambodia. That’s actually an advantage.

• Industrial fuel demand is increasing
• Coal replacement pressure is growing
• Export potential exists (Vietnam, Thailand)

Wood and bamboo residues are widely available but underutilized. That’s exactly why this 20t/h industrial wood bamboo pellet manufacturing factory in Cambodia makes sense.

What This Project Shows

This project wasn’t just about selling a biomass pellet production line.

It was about:

• Understanding raw materials that are not ideal
• Designing a process that tolerates variability
• Making sure the plant can actually run daily

We handled:

• Process design
• Equipment manufacturing
• Layout planning
• Installation & commissioning
• Operator training

If you’re sitting on wood waste, bamboo residues, or similar materials, the question is not “can it be pelletized?”

The real question is:
“Can it be pelletized consistently, at scale, and profitably?”

That’s where experience makes the difference.

If you want, we can look at your raw materials first—no pressure to jump into a full biomass pellet project. Sometimes a few samples tell more than a long discussion.
