ABC Machinery has delivered two wood pellet lines in Vietnam, at 4–5 t/h and 32 t/h. Almost every difference in their equipment configuration traces back to feedstock conditions rather than capacity targets. This article does not discuss how large the Vietnamese market is. It answers one equipment question: under Vietnam’s feedstock and acceptance conditions, which machines a wood pellet line needs, how to choose the core pellet mill, and which stages can be deferred. Each stage below is paired with its selection criterion rather than a rule of thumb.
How to Select Wood Pellet Manufacturing Equipment for Vietnamese Feedstock
Local feedstock is dominated by sawdust and shavings from acacia plantations, plus branch and top material of roughly 2 cm diameter or less. Feedstock form, moisture content and contaminant level then determine the pre-treatment, drying and cleaning stages respectively.
Feedstock Form Drives the Pre-treatment Set
Vietnamese pellet plants draw on two source types with very different behaviour:
| Feedstock type | Source | Particle state | Pre-treatment configuration |
|---|---|---|---|
| Wood-processing residues | Sawmill sawdust and shavings | Already close to pelletising size | Screening + metal removal; coarse crushing can be omitted |
| Plantation branches and tops | Short-rotation plantations such as acacia | Oversized, requires size reduction | Chipper or hammer mill + screening + metal removal |
One caveat: Vietnam’s pellet feedstock chain depends on by-products from other wood-processing industries, so the source is dispersed and batch quality is unstable. The biomass pellet making equipment consequence is that the line must tolerate frequent feedstock switching — feeding and screening need generous tolerance, and cannot be narrowly designed around a single feedstock’s particle size.

Raw Material and Final Products Made by Biomass Pellet Line
Moisture Content Drives the Drying Decision
| Feedstock moisture | Assessment | Drying configuration |
|---|---|---|
| Stably below the pelletising requirement | Drying can be omitted | Retain screening and metal removal only |
| Volatile or persistently high | Drying is mandatory | Drum dryer + hot-air furnace + dust collection |
| Stored in the open, rainy season | Drying mandatory with spare capacity | Drying capacity sized to the worst-case moisture |
Moisture in openly stored feedstock varies markedly with season, so Vietnamese projects normally size the drying stage against the least favourable condition rather than an average. This has to be settled at the selection stage — retrofitting a dryer later costs far more than sizing it correctly once.
Contaminants and Chemical Residues Drive the Cleaning Stage
This is where Vietnamese biomass pellet manufacturing projects differ most from other markets. Japanese and Korean buyers have moved from “is the calorific value high enough” to “will this fuel damage the boiler”, and the rejection items are specific:
| Contaminant | Consequence | Equipment response |
|---|---|---|
| Plastic bags, metal fragments | Power plant equipment damage; fires and explosions have occurred | Screening + metal removal + air separation |
| Sodium and potassium residues | Boiler slagging and corrosion | Control bark content, or add a debarking step |
| Particle size and moisture variation | Unstable forming rate and durability | Stabilise pre-treatment and dryer discharge |
Factoring in the EUDR requirement, the cleaning stage carries a second function: producing traceable records of feedstock origin and batch. In other words it is not only quality equipment, it is also compliance wood pellet making equipment.
What this means for buyers: the uncertainty in Vietnamese feedstock is not whether material exists, but whether it is stable and clean. Send us your feedstock photos and moisture range, and we will size the pre-treatment and drying configuration against the worst case.
What Biomass Pellet Making Equipment a Wood Pellet Line Contains
A complete wood pellet line has four stages — pre-treatment, drying, pelletising, and cooling and packing. What determines whether the finished pellets pass acceptance is the cleaning capacity of the pre-treatment stage and the stability of the drying stage, not the pellet mill itself.
The process train is fixed:
Feedstock intake → pre-treatment (crushing / screening / metal removal) → drying → pelletising → cooling → finished-product sifting → bagging
Equipment composition and selection criteria by stage:
| Stage | Core equipment | Function | Selection criterion |
|---|---|---|---|
| Feedstock intake | Separator bins | Separate material types, stabilise feeding | Whether feedstock is multi-source |
| Pre-treatment | Chipper / hammer mill | Reduce logs, branches and slabs to pelletising size | Feedstock dimensions |
| Pre-treatment | Sieving machine | Remove oversized and fines, stabilise particle size | Particle size distribution |
| Pre-treatment | Metal remover (+ air separation) | Remove metal fragments and light contaminants | Contaminant form (BPA warning item) |
| Drying | Drum dryer + hot-air furnace | Bring feedstock moisture into the pelletising range | Feedstock moisture content |
| Pelletising | Ring-die or flat-die pellet mill | Core machine, forming | Capacity positioning and feedstock type |
| Cooling | Counter-flow cooler | Bring formed pellets down to bagging temperature | Capacity match |
| Post-treatment | Finished-product sifter | Remove fines, raise finished yield | Finished-product requirement |
| Bagging | Weighing and bagging machine / manual bagging | Weighing and bagging | Automation tier (see below) |

Core Machine: Where Ring Die and Flat Die Diverge
The pellet mill is the only machine genuinely selected by capacity — but the boundaries between machine families matter more than the capacity figure. ABC Machinery’s wood pellet mills fall into four families:
| Machine family | Structural character | Suitable feedstock | Typical use |
|---|---|---|---|
| Horizontal ring die | Die arranged horizontally, capable of continuous heavy-load running | Sawdust, shavings, crushed wood chips | Export-grade commercial lines |
| Vertical ring die | Die arranged vertically, even feeding and more even die wear | Wood chips, straw, rice husk | Medium-to-large continuous production |
| Flat die (rotating disc / roller) | Compact, quick to change material | Small batches, multiple material types | Small capacity and trial lines |
| Mobile integrated set | Integrated layout, relocatable | Scattered feedstock points | Dispersed feedstock, on-site processing |
The selection order is: first whether the feedstock form can enter the die reliably, then daily running hours, and only then the capacity figure. Long-cycle export projects almost always land on horizontal or vertical ring die; flat die and mobile sets suit trial orders, multi-product operation, or dispersed feedstock.
Port Loading Scene of Biomass Pellet Line Complete Set
Configuration reference: the table below is the actual configuration of ABC Machinery’s Vietnam projects and can serve as a benchmark for equivalent scale. Specific selection must be recalculated against your own feedstock conditions.
| Project | Capacity | Feedstock | Equipment delivered |
|---|---|---|---|
| Vietnam project (4–5 t/h) | 4–5 t/h | Sawdust + shavings | Separator bins, sieving machine, BPM508 ring-die pellet mill, cooler; process includes drying; finished pellets bagged manually |
| Vietnam project (32 t/h) | 32 t/h | Biomass | See project page |
What this means for buyers: the automation and integration decisions determine whether the line merely runs or runs profitably and continuously. Tell us your power supply conditions and site dimensions, and we will fix the electrical control and dust-collection tiers directly in the layout proposal.

What this means for buyers: the window in Vietnam is narrowing — Japan stopped approving new subsidies in 2025 and the EUDR applies in 2026, tightening both routes at once. Send us your feedstock conditions, target capacity and target markets, and one feedstock assessment will tell you whether the project path is worth taking.
