3 T/H Hardwood Pellet Plant in Poland

RICHI MACHINERY

Regional Industrial Buyers Define the Fuel Quality

The customer’s woodworking background provided familiarity with sawdust collection and timber suppliers. Equipment discussions began in 2024, with the project shaped around regional residues and the practical use of an existing leased site.

Accepted furniture residues come from unfinished solid wood processing. Coated parts, glued board and chemically treated wood are kept outside the clean fuel route. That separation starts at the supplier and continues through receiving.

The customer focuses on industrial fuel users and distribution opportunities around Wielkopolskie. Regional transport keeps the supply chain tied to the scale of the plant, while bagged and bulk handling serve different buyer storage arrangements.

The wood pellet manufacturing plant produces fuel to a defined moisture, ash, fines and durability specification. Those characteristics connect the wood blend with the buyer’s heating equipment and determine how the pellets are packed and handled.

RICHI arranged preparation and pressing around the three available residue forms, with separate attention to hard sawdust, light shavings and wetter mixed fines.

Measure the Three Material Streams Separately

Three suppliers provide residues from furniture production, flooring manufacture and sawmilling. Their different material forms affect unloading, stock volume and feed preparation. The purchasing schedule is: Hardwood sawdust is denser than fluffy shavings, so a similar floor volume can contain different material weights. The operator keeps the streams identifiable rather than selecting a blend by loader-bucket count alone. For a new hardwood installation, samples and measured bulk density help RICHI compare bin geometry and feeder duty.

Hardwood sawdust at 12–18% moisture forms the largest supply allowance. Loads beyond the tested pressing window need segregation, treatment or restricted use in a measured blend. Rough milling before finishing reduces contamination risk only while collection remains separate. An accepted supply specification should describe both moisture and the collection stage. Sawdust from clean machining can be useful, while dust collected after finishing may contain coatings or other unsuitable material. Clear separation at the supplier reduces the work needed at the plant and protects the intended fuel application.

Softwood shavings add a lighter stream to the blend. They need consistent feeding because loose material can bridge above a bin outlet. Grinding and measured blending prepare this fraction for the same pressing route as the denser hardwood sawdust.

Mixed fines arrive at approximately 15–20% moisture. They remain separate from the drier stock so that operators can control their contribution to each production batch. Covered storage protects all accepted material from further rain exposure.

The annual supplier pool supports collection planning, while daily production follows accepted moisture and available pressing hours. Weighed stock movements and finished-product dispatch give the customer a practical yield record without treating every incoming tonne as bagged fuel. The 15,500-tonne supplier pool also allows for material delivered near the end of a production period and used later. Keeping purchasing, stock and production records distinct helps the customer plan vehicle movements and avoid receiving more loose material than the covered area can hold.

Six Compact Presses Share the Prepared Meal

The installation uses six 350-series biomass presses with 37 kW drives. Running the machines together provides the 3 T/H production arrangement, while independent feeding lets the operator balance loading and isolate a press for service.

The equipment package cost US$195,000 on an ex-works basis.

Each wood pellet mill receives prepared meal through the common distribution route. The wood pellet production line uses all six units for its combined pressing duty, with individual feed adjustment helping balance material between machines.

A modular pressing arrangement gives the maintenance team access to one machine at a time. Available output reduces when a press is stopped, but the remaining units can continue receiving meal where the common upstream equipment remains in service. The layout therefore benefits from accessible feed isolation and space to move tools around the stopped machine. Planning those movements matters more with several compact presses than with a single large unit: the service position must remain usable while people continue operating nearby equipment.

Independent isolation and feeding at each press make routine die and roller work more manageable. Service planning follows wear condition and the two-shift production calendar.

The six press drives total 222 kW. Together with the 55 kW crusher and two 75 kW grinders, the main preparation and pressing drives account for 427 kW. Conveying, extraction and downstream handling add their own electrical duties.

Moisture Acceptance Before the Grinding Route

The hardwood pellet production line in Poland uses accepted dry material without a thermal dryer. Separate stock areas let the operator control the proportion of wetter fines before the material reaches the grinding and pressing route.

Covered Receiving
Hardwood sawdust, softwood shavings and mixed fines enter separate stock areas. Receiving checks remove contaminants and keep wetter deliveries apart from the material ready for production.

Measured Blending
The operator selects proportions from the moisture and condition of the available stock. Consistent blending keeps press resistance more stable as deliveries change between suppliers.

Oversize Preparation
The 55 kW crusher handles larger pieces separated from the sawdust and shavings. Routing only the oversize fraction through this stage keeps the main meal supply moving without unnecessary crushing.

Fine Grinding
Two 75 kW grinders prepare material for pressing. Screen inspection, aspiration and even feeding keep the meal distribution consistent across the parallel press arrangement. Differences in hammer condition or airflow between the two grinders can change the meal reaching the presses. Comparing the discharge from each machine gives the maintenance team a useful check before adjusting every press. Consistent preparation reduces the number of variables the operator has to manage downstream.

Parallel Pelleting
Each wood pelletizer machine receives a controlled feed. Operators follow motor load and pellet condition at the individual units, with die and roller service scheduled around wear and the production roster.

Cooling and Screening
The wood pellet press discharge passes through counterflow cooling before screening. Saleable pellets leave with reduced temperature and loose fines removed, while compatible screened material returns in controlled quantities.

Packing
The filler serves 15–25 kg bags. Bag weight, sealing and pallet handling are coordinated with line output so that finished product moves promptly into covered stock. Bagging speed alone does not clear product from the line. Sealing, pallet stacking and movement into stock need enough space and labour to follow the filler. Buyers selling both bulk and small bags should identify the expected order pattern so RICHI can compare dedicated or shared handling arrangements.

Extraction Depends on Flow and Filter Area

Extraction collects dust from preparation and material transfer points. The two-stage arrangement keeps coarse separation and fine filtration accessible to the maintenance team.

Grinding airflow, hood condition and filter resistance influence collection performance. Routine checks keep the air route clear as sawdust and shavings pass through different preparation duties.

Measure pressure drop and airflow at the operating load.

Receiving residues remain separate from compatible process fines. This prevents unwanted material collected at the intake from entering the finished-fuel recycle route.

Accessible filters, sealed joints and regular cleanout make dust handling part of the operating routine across both shifts.

Operating Costs Follow Material and Machine Duty

The wood pellet processing plant cost depends on accepted material, electrical use, labour, rent and wear parts. The customer tracks these costs against saleable output, with grinding and pressing forming the largest motor duties.

Product formats and commercial considerations:

The cost of a saleable tonne includes more than the wood blend. Reliable feeding reduces interruptions, accessible machines shorten service work and protected bags reduce handling damage. These are practical levers for a woodworking business moving into regular fuel deliveries. For a six-press arrangement, spare inventory needs coordination. A compatible die or roller set is useful only when it matches the machine being serviced. Keeping wear records by press position helps the team identify uneven feeding or maintenance differences that would otherwise appear as unexplained changes in the overall production cost.

The project funding budget totalled US$280,000, including operating funds. Machinery and logistics accounted for US$205,000. The equipment price remains distinct from site work and the cash used for materials and daily operation, making it easier to compare this leased-site project with a new-build plant.

Service Access Across a Six-Press Workshop

The parallel arrangement makes individual press service possible while the remaining units continue. Preparation, meal distribution and product handling still connect the whole installation.

Press-room routines:

• Balance feed between the six machines and track motor load.
• Use measured moisture and weighed blends across supplier changes.
• Keep wet stock segregated when a no-dryer blend cannot be achieved.

Workshop routines:

• Balance each extraction hood against filter and fan duty.
• Protect material from lateral rain exposure as well as overhead rain.
• Check filling, sealing and pallet movement at the actual finished-product rate.

Shipment Costs and Fixed Expenditure

Three 40-foot containers carried the machinery through Gdańsk in 2024, followed by inland delivery to Wielkopolskie. Combined logistics cost US$10,000.

Equipment and logistics together cost US$205,000. The leased building and local installation arrangements supported a compact project focused on material preparation, pressing and product handling.

RICHI supported machinery installation and operator handover, with local work covering the site’s physical and electrical connections.

Fuel Specifications Connect the Plant to Its Buyers

Regional heat users evaluate pellets by moisture, ash, fines, durability and the way the product moves through their storage and feeding equipment. The project’s commercial focus follows those practical requirements.

Bulk and bagged formats serve customers with different unloading and storage systems.

Industrial fuel specifications must match the buyer’s combustion equipment. Consistent feedstock acceptance and finished-product testing give the producer a clear basis for discussing supply quality.

A hardwood pellet factory in Poland can serve regional users through delivery batches matched to customer stock space and seasonal heating demand. Transport cost and product handling belong in the sales calculation alongside factory-gate price. The 2,600 m² site gives the customer room to protect raw material and prepare dispatch, but seasonal stock still needs scheduling. Product should remain accessible for rotation and inspection. A sales programme built around realistic delivery batches reduces the chance that finished pellets occupy the working area needed for fresh residue.

RICHI can use the intended fuel application to guide die choice, screening and packing for another hardwood-residue project. Include the required delivery format when requesting sample production or a complete equipment quotation.

RICHI Support From Blending to Bagging

RICHI’s project work covered:

• Material preparation and meal distribution across six presses.
• Equipment interfaces for cooling, screening and extraction.
• Installation support and practical performance tests.
• Operator instruction on feed balance, die service and safe isolation.
• Spares matched to the identified drives and wear components.

Technical support uses measured inlet moisture, motor load, throughput and product quality to diagnose problems. Keeping a separate record for each press makes that advice more useful. A change affecting one unit suggests a different investigation from a change affecting the whole room. Feed distribution, upstream preparation and common extraction can then be checked before individual machine settings are altered across the installation.

Size a Pellet Line Around Your Hardwood Supply

For a hardwood pellet plant in Poland, provide the retained or proposed machine data with representative material samples:

• Moisture distribution by stream and proportion exceeding the accepted limit.
• Sawdust and shavings proportions, maximum piece size and available preparation equipment.
• Press models, motor labels, die specifications and actual loaded throughput.
• Buyer limits for ash, moisture, fines, durability and packing.

Include your available working hours, staffing plan and building dimensions. RICHI can compare parallel presses with other biomass configurations and show how preparation and product handling affect the full line.

The inquiry should also identify bagged or bulk dispatch and the buyer’s fuel limits. For bulk users, include the receiving vehicle and unloading method. For bagged distribution, include bag weight, pallet format and expected order size so that filling and dispatch can be designed together.

Send the material samples and site drawing for an equipment proposal matched to your hardwood supply, with machinery, installation and logistics costs set out separately. For a plant already operating, include a short account of the stage that limits daily production. The best addition may be preparation, feed distribution or product handling rather than another press. RICHI can compare these options against the site drawing and the desired increase in dispatched fuel.
