Waste Wood Pelletizing Plant in Chile

RICHI MACHINERY

Project snapshot

This 2t/h waste wood pelletizing plant in Chile is designed for an annual output of 5,000 tons, running under a straightforward schedule:

• 8 hours per day
• 300 working days per year
• Total: 2400 hours/year

The plant employs 10 workers, with no on-site accommodation—typical for small-to-mid-scale biomass operations in Chile.

From a footprint perspective, the facility is compact but efficient:

A short story behind the project

The client runs a small logistics and recycling operation near Santiago. Over the years, they accumulated a steady supply of:

• broken pallets
• packaging wood
• construction leftovers

At first, they tried selling it as scrap. Didn’t work well—prices were unstable, and transport cost ate most of the margin.

The first email came in March 2024. It was simple:
“Can we make pellets from mixed waste wood without drying?”

That question alone already told us quite a bit.

By May 2024, after several rounds of raw material analysis and layout discussion, the project was signed. The client wasn’t chasing high capacity—they wanted stable output and low risk.

Product positioning

The plant produces a single, consistent product:

These pellets are mainly sold for:

• industrial boilers
• small-scale heating systems
• export traders (bulk shipments)

Raw materials – not as simple as it sounds

In Chile, waste wood streams are not always clean. That was one of the first things we discussed.

The client’s raw material mix looks like this:

Moisture content averaged around 10%, which is why we skipped the drying system entirely. That saved both investment and operational cost.

But here’s the catch:
Some batches had nails, paint residues, or small metal fragments. Without proper removal, the pellet mill wouldn’t last long.

Equipment configuration

The wood pellet processing equipment list is not long, but every piece plays a role.

A lot of customers expect more wood pellet making equipment. In this case, fewer machines actually meant better reliability.

How the process actually runs

The 2t/h waste wood pelletizing plant in Chile follows a straightforward process, but small details matter.

Step-by-step flow:

1. Manual sorting
   Workers remove oversized or unsuitable materials.
   (Honestly, this step is often underestimated. It saves a lot of trouble later.)
2. Magnetic separation
   A magnetic separator pulls out nails and metal fragments.
   Without this, the pellet die life drops fast.
3. Crushing
   • No drying required
   • Direct size reduction
   • Generates dust (handled later)
   First few days during commissioning, particle size was uneven. We adjusted the screen—problem solved.
4. Pelletizing (core step)
   • Roller extrusion
   • No external heating
   • Raw material: ~5002 tons/year
   The first few tons? Not perfect. Some pellets cracked due to inconsistent feed rate. After stabilizing feeding, quality improved noticeably.
5. Loading & delivery
   Finished pellets are loaded directly using loaders.

Environmental control

The client was quite concerned about dust. Local inspections can be strict, especially near industrial zones.

So we designed:

• Dust collection system
  • Crushing dust → bag filter → 15m stack
  • Pelletizing dust → bag filter → separate stack
• Wastewater
  • Only domestic wastewater
  • Septic tank + municipal system
• Solid waste
  • Dust collected and reused
  • Domestic waste handled by local services
• Noise control
  • Equipment isolation
  • Foundation damping

Nothing overly complicated—but it works, and it passes inspections.

Utilities and consumption

This wood pellet plant construction project is light on utilities, which is one reason the client moved forward quickly.

Power

• Supplied by local grid

Water

No process water needed, which simplifies operation.

Layout thinking

The layout seems simple now, but we revised it three times.

Main considerations:

• Keep raw material area close to crusher
• Separate pelletizing zone for dust control
• Leave enough turning radius for loaders

The final layout is rectangular, compact, and easy to operate.

Investment overview

The client didn’t want a heavy upfront investment.

• Equipment cost: ~$85,000
• Total project investment: ~$160,000

For a 2t/h biomass pellet plant in Chile, this sits at the lower-middle range, which made the decision easier.

A few practical questions the client asked

Can we skip drying?”
Yes, if moisture stays around 10%. Otherwise, no.

“What about mixed wood types?”
Fine, as long as contaminants are controlled.

“Is one pellet machine enough?”
For 2t/h and stable operation—yes.

Market outlook in Chile

Chile has been pushing biomass energy, especially in regions with high heating demand.

A few practical observations:

• Firewood is still widely used, but regulations are tightening
• Pellets are becoming a cleaner alternative
• Small pellet plants fill local supply gaps

So a waste wood pellet production line in Chile like this one fits well:

• raw material is cheap
• demand is growing
• logistics is manageable

This biomass pellet project didn’t rely on complex technology. It worked because the process matched the material, and the scale matched the market.

That’s usually where things either succeed or fail.

If you’re looking at a 2t/h waste wood pelletizing plant, the first thing we’ll probably ask you is not about capacity—but about your raw material. That’s where everything starts.
