2.5–3.0 T/H Oil Palm EFB Pellet Mill in Thailand

Chumphon Gives the Project a Real EFB Supply Base

Southern Thailand has a long-established palm oil industry, and Chumphon is a credible location for collecting empty fruit bunches from palm oil processing. EFB is generated at the mill after fruit removal, so the project is built around short-haul collection from processing sites rather than forestry residues or municipal biomass that would require a separate sourcing and contamination-control system.

The customer focuses on industrial fuel rather than residential wood-pellet markets. EFB has a different ash chemistry from clean stemwood, including higher alkali-related combustion concerns, so the plant does not present every pellet lot as a direct substitute for premium wood pellets. Fuel acceptance depends on laboratory results and the combustion system used by the buyer.

Rubberwood sawdust is available in southern Thailand and can be evaluated as a secondary biomass stream when a customer specification justifies blending. It is not assigned a permanent percentage in this case. Pure EFB, EFB-rich fuel and blended biomass can behave differently during grinding, pelletizing and combustion, so each commercial grade is tested separately before routine production.

MZLH678 Matches the Existing EFB Preparation Section

The 2.5–3.0 T/H figure applies to suitably prepared biomass rather than fresh EFB arriving from a palm oil mill. Fibre moisture, particle size, bulk density, ash contamination, die specification and feeder stability all affect real output. The plant therefore plans production from actual prepared-fibre performance instead of treating the top reference figure as a guaranteed rate for every batch.

One MZLH678 biomass pellet machine also suits this project better than a pair of MZLH520 units because the existing cooler, screen and material buffer are built around one production train. A single press reduces duplicate feeders and transfer points while still giving more hourly capacity than one MZLH520. Future parallel capacity is considered only after the preparation and downstream sections show enough reserve.

Fresh EFB Requires Several Steps Before Ring-Die Pelletizing

Fresh empty fruit bunches are bulky, springy and normally too wet for direct pelletizing. The receiving section first opens and shreds the bunch structure so moisture reduction becomes more effective and the material can move through conveyors without severe bridging. Where incoming water is high, mechanical dewatering can be evaluated before thermal drying to reduce the heat load on the dryer.

After drying, the fibrous EFB passes through secondary size reduction so the pellet mill receives a much finer and more uniform fraction. Research on EFB processing commonly uses material below a few millimetres for densification studies, but the plant does not lock production to one universal screen opening. Fibre length, moisture and die loading are checked together during commissioning.

Moisture is controlled around the actual forming behaviour rather than one permanent 8–12% rule. Material that is too wet can feed poorly and form soft pellets, while excessively dry fibre can increase dust and compression resistance. The useful operating window is established from feeder stability, motor load, pellet surface, fines and cooler performance with the active EFB grade.

Where the Oil Palm EFB Pellet Mill in Thailand Fits the Process

1. EFB is collected from palm oil mills and inspected for foreign material.
2. The bunch structure is opened and shredded for easier handling and moisture removal.
3. Water is reduced by mechanical and thermal methods where required by incoming condition.
4. Dried fibre is finely milled and transferred to a prepared-material buffer.
5. The MZLH678 compresses the fibre through an 8 mm ring die.
6. Hot pellets are cooled, screened and moved to bulk storage or packing.

The Oil Palm EFB Pellet Mill in Thailand performs the densification step only. It does not replace shredding, dewatering, drying or fine grinding, and it cannot compensate for poorly prepared long fibre. Keeping those duties separate is important with EFB because its low bulk density and fibrous structure can create unstable feeding long before material reaches the compression zone.

The cooler is sized to the pelletizer's instantaneous discharge rather than the plant's average daily tonnage. Hot pellets need enough time to stabilize before bulk storage, while screening removes loose fines and gives operators feedback on material preparation and die condition. Persistent fines are investigated at the process level instead of being treated only as a screening problem.

Eight-Millimeter EFB Pellets Fit the Industrial Fuel Duty

The main product is an 8 mm fuel pellet. Published EFB pellet research includes both 6 mm and 8 mm products, and 8 mm is a credible format for industrial biomass handling. The machine can physically make other diameters within its 4–12 mm range, but this project does not select a larger size simply because the ring die can produce it.

Pellet length is controlled by cutter setting and operating condition, so the case does not invent one exact commercial length without a buyer specification. Diameter and length are physical dimensions only. They do not prove calorific value, ash performance or boiler compatibility, which must be determined from the actual EFB fuel and the combustion requirements of the customer.

EFB fuel quality also needs more than density and appearance. The processor tests moisture, ash, mechanical durability and calorific value, while buyers may also require information on potassium, chlorine and other ash-related elements. These factors matter because EFB can create slagging, fouling or corrosion concerns in combustion systems that were designed around cleaner woody biomass.

Dust, Wear and Fuel Chemistry Need Industrial Controls

Dry milled EFB generates fine combustible dust, so enclosed transfer, aspiration, filtration, grounding and housekeeping are included around the grinding and pelletizing area. Airflow is sized from real pickup points and duct resistance rather than a generic dust-removal percentage. Bearings, friction points and material buildup are inspected as part of routine fire-risk management.

Wear is tracked by processed tonnes and material cleanliness instead of one promised service life. Sand, soil and mineral contamination collected with the bunches can accelerate hammer, die and roller wear. Magnetic protection helps with ferrous debris, but stones and non-ferrous contaminants need receiving inspection and suitable separation before the prepared fibre reaches high-speed equipment.

The 200 kW main motor is only part of the section load. Shredders, dewatering equipment, dryer auxiliaries, fine grinding, conveyors, cooler fans, screening and dust collection add substantial demand, so the customer checks the complete electrical system. Thermal energy for moisture removal can also be a major operating cost when incoming EFB is very wet.

Shipping and the Next Capacity Step

For a Chumphon biomass pellet project, imported machinery can enter Thailand through a major deep-sea gateway and continue south by road according to the forwarding plan. The article does not assign a fixed port, sea-transit period or customs duration because routing depends on carrier service, package dimensions and inland delivery arrangements at the time of shipment.

The next expansion decision starts with prepared EFB supply rather than another pellet mill. If shredding, moisture reduction, fine grinding, cooling or storage is already full, a second press would only transfer the bottleneck. The plant first measures where fibre accumulates and how many pelletizing hours are available before adding parallel ring-die capacity.

For another buyer evaluating an Oil Palm EFB Pellet Mill in Thailand, RICHI Machinery would review fresh EFB tonnage, collection radius, incoming moisture, existing shredder and dewatering equipment, dryer evaporation capacity, target particle condition, 6 or 8 mm pellet requirement, hourly fuel demand, cooler capacity, electrical supply and buyer fuel specification before confirming the machine scope.
