Wood Pellet Factory Construction in Chile

RICHI MACHINERY

How This Project Started

The client operates a mid-sized woodworking workshop in southern Chile, mainly processing pine and mixed hardwood for construction use. For years, waste was simply stacked or sold cheaply to nearby users.

Around March 2024, the client reached out with a straightforward question:

“We don’t want a big plant. Just something that runs reliably and doesn’t eat too much power. Can 5 tons per hour actually work for pellets?”

By May 2024, after several rounds of layout adjustments and raw material testing discussions, the project contract was signed.

The idea wasn’t to build a large biomass energy facility. Instead, the goal was:

• stabilize waste disposal
• create an additional revenue stream
• keep investment controlled

That’s why the capacity stayed at 5t/h, even though raw material supply could support more.

Raw Material Situation

At first glance, “wood waste” sounds simple. In practice, it wasn’t.

The material came from:

• pine processing scraps
• hardwood trimming residues
• occasional mixed wood blocks

Moisture fluctuated depending on season. Some batches were close to 10%, others went above 20%. That’s why the process had to tolerate variation rather than assume ideal input.

Raw Material Consumption

A small but important detail:
During early discussions, the client considered buying cheaper mixed waste. That idea was dropped after explaining how adhesives would affect pellet quality and emissions.

Plant Layout — A Simple Rectangle, But Not Random

The workshop is a rectangular 2,600 m² enclosed building. No fancy structure, but enough height to handle conveyors and airflow.

Originally, finished products were planned in the north area. During installation, this was shifted to the south side. It sounds minor, but it actually improved forklift movement and reduced crossing paths.

Functional Zoning

• Production zone: center of the workshop
• Raw material storage: west side (~400 m²)
• Finished pellet storage: south side (~1000 m²)
• Solid waste area: inside workshop (~10 m²)

Material flow is kept linear. No backtracking. That helps more than people think.

Equipment Configuration

No oversized configuration here. Everything was selected to match the 5t/h throughput.

Equipment List

One thing noticed during commissioning:
Running two wood pellet extruder machines instead of one larger unit gave better flexibility. When moisture fluctuates, operators can adjust load between machines.

Process Flow — Not Complicated, But Needs Control

Instead of over-designing, this wood pellet production line follows a classic route. What matters is stability.

Production Steps

1. Crushing
   • Wood offcuts are fed into the crusher
   • Output size: ~40×50 mm blocks
   • Magnetic separation removes nails
   • Dust collected via hood + bag filter
2. Grinding
   • Crushed wood enters hammer mills
   • Final size: ≤14 mm sawdust
   • Negative pressure system moves material
   • Dust again routed to central bag filter
3. Pelletizing
   • Screw conveyor feeds material into wood granulator machines
   • No additives, purely physical compression
   • Final pellet diameter: 8 mm
   • Dust collected from machine exhaust
4. Cooling & Storage
   • Pellets transferred via belt conveyor
   • Stored in finished product area

Dust Control — A Key Adjustment During Installation

Originally, only a bag filter system was planned.

During commissioning, operators reported visible dust in crushing and grinding zones. Not extreme, but enough to justify improvement.

So an additional step was introduced:

• spray mist system in critical areas

This reduced airborne dust significantly without affecting material moisture too much.

Water & Utilities

Water usage is minimal and controlled.

No process wastewater is generated. Most water from spray evaporates.

Power supply comes from the local industrial grid. No special infrastructure required.

A Few Things That Didn’t Go Perfectly

Not everything worked immediately.

During the first trial:

• some material was too wet → pellets came out soft
• then too dry → production dropped

Operators had to learn to “read” the material:

“After a few days, they could tell just by touching the sawdust.”

That’s the kind of adjustment no manual really teaches.

Shipping & Logistics

• Port of departure: Qingdao Port, China
• Destination port: Port of San Antonio, Chile

All wood pellet processing equipment was shipped by sea in standard containers. No oversized cargo was required, which kept logistics costs reasonable.

Why This Type of Project Works Well in Chile

Chile has a strong wood processing industry, especially in the south. That means:

• steady supply of wood residues
• growing demand for biomass fuel
• increasing pressure on waste management

Small-to-medium pellet plants like this one fit well:

• manageable investment
• quick installation
• flexible operation

This biomass pellet project didn’t aim to be the biggest. It aimed to be stable — and that’s exactly why it works.

A Practical Takeaway for New Buyers

Many clients ask whether they should start with a larger plant.

From this case, a few observations:

• A 5t/h wood pellet factory construction in Chile is enough to build experience
• Raw material consistency matters more than capacity
• Layout planning affects daily efficiency more than expected

And one thing that often gets overlooked:

It’s better to run a small plant well than struggle with a large one.

What This Project Really Shows

This project is not about scale. It’s about control.

From raw material handling to dust management, every small decision adds up. The line itself is not complicated, but making it run smoothly took real adjustments.

For anyone considering a similar 5t/h wood pellet factory construction in Chile, the first step is not choosing equipment — it’s understanding your material.

That’s usually where the real conversation starts.
