Crop Straw Wood Pelletizing Plant in Chile

RICHI MACHINERY

A Shared Forming Train with Two Moisture Routes

The customer has an existing 800 m² workshop and an extension bringing the covered working allocation to approximately 2,600 m². This wood pellet production line layout separates wet intake from dry prepared material, then combines the qualified streams ahead of the presses.

The crop straw wood pelletizing plant in Chile uses a sizing basis in which about 20% of incoming material can bypass drying and up to 80% needs thermal treatment. These percentages describe incoming material by mass. Qualified dry material still receives the size, blending and metal checks required for the selected product.

The customer gains a defined production route for changing supply conditions, with dryer load assessed before wet material reaches the forming stage.

Agricultural Residues with an Industrial Product Destination

The client works across grain farming and timber-residue handling in southern Chile. Its crop residue pellet plant combines identified straw supplies with sawdust from qualified processors, giving each supplier a measurable acceptance specification.

A biomass pelletizing plant can add a fuel product when those materials suit the intended buyer. RICHI’s design focuses on controlled preparation, moisture and blending so the customer can discuss delivery lots with an industrial heating user in practical terms.

The crop straw wood pelletizing plant in Chile supplies a mixed biomass fuel. Product qualification includes ash and combustion behaviour, particularly when the agricultural fraction changes.

Separate Supplier Lots before Blending

Material	Procurement allowance	Receiving condition	Preparation duty
Agricultural straw	Around 9,000 tonnes/year	Identified bales, moisture and contamination checks	Remove bindings and cut fibre
Sawdust and wood powder	Around 19,000 tonnes/year	Untreated material, classified by moisture and particle condition	Use the drying or size-preparation bypass only when qualified

The combined allowance supports the annual product basis under the selected moisture and loss conditions. It is a purchasing envelope, with actual use recorded by lot and blend.

This biomass pellet project keeps treated wood, glued boards, soil-rich residues, plastic and metal outside the accepted fuel route. Qualified dry material receives the particle-size and blend checks needed for a consistent industrial product.

The biomass pellet plant buffers the prepared blend so a brief receiving interruption does not immediately disturb the two forming feeders.

Two Mills Serve the Eight-Tonne Finished Duty

Main equipment	Quantity	Selection basis
Straw bale opener and cutter	1	45 kW main drive for the agricultural fraction
Wet-material dryer and heat supply	1 set	3.5 tonnes/hour water evaporation basis
Biomass hammer mill	1	200 kW main drive for the selected fine-preparation duty
Biomass pellet mill, MZLH768	2	250 kW main drive each, selected 8 T/H combined duty
Counterflow cooling and grading	1 matched arrangement	Handle the combined formed product
Weighed bagging and dispatch	1 coordinated set	At least 4 bags/minute at 50 kg when bagging the full output

Each appropriate biomass fuel pellet machine serves a selected 4 T/H forming duty, giving the pair an 8 T/H combined basis. Controlled feed distribution, shared fine preparation and matched finishing connect those two machines to the factory’s product requirement.

Sawdust that already meets the particle specification can bypass unnecessary grinding. A wood chipper is outside this sawdust-and-straw scope; a new bulky-wood supply would require its own coarse preparation assessment.

The Crop Straw Wood Pelletizing Plant in Chile Process

Inspect and classify each delivery

Staff identify the supplier lot, contamination condition, particle size and moisture. Wet and qualified dry stocks stay separate at receiving.

Open and cut the straw

The bale opener removes bindings and presents a controlled feed to the cutter. Prepared short fibre takes the appropriate bypass.

Dry the wet material

Metered feeding keeps the wet fraction within the dryer duty. Air movement, heat input and feed rate are coordinated, with discharge moisture checked by sampling.

Prepare the dry bypass

Qualified dry sawdust or other approved dry material bypasses thermal treatment. It enters the shared preparation route only after the required size and contamination checks.

Grind and blend the two routes

The common grinder prepares material where its particle distribution needs correction. Metered blending maintains the approved composition before buffering and forming.

Form in the two presses

Each biomass wood pellet machine receives its share of the prepared flow. The selected die and feeding conditions follow the approved blend and 8 mm industrial product.

Cool, grade and dispatch

The cooling arrangement removes heat before screening and stock. Clean compatible fines return through the identified route. Released pellets enter weighed bags or the agreed bulk format.

Output and Product Acceptance

The annual operating basis is 8 T/H multiplied by ten net hours per day and 250 production days: 20,000 tonnes. Scheduled two-shift coverage provides time for preparation, checks, maintenance and material changes around those hours.

The crop straw wood pelletizing plant in Chile targets an 8 mm pellet and approximately 10–30 mm product length, with finished moisture at or below 10%. Bulk density and mechanical durability are measured against the agreed specification, alongside fines, heat value, ash and relevant chemistry.

Acceptance covers the product after cooling and screening. Output weighing and product sampling at that stage establish the factory’s saleable quantity, physical condition and conformity with the agreed fuel specification.

Dryer Calculation and Utility Planning

For sizing, the wet fraction is assessed at 40% incoming moisture and dried to approximately 12%; the dry bypass is assessed at 12%. At the 8 T/H finished-product basis, a modest dry-matter loss allowance gives approximately 11.2 T/H of combined incoming material.

About 8.96 T/H enters the wet route under the 80% assumption. Reducing that fraction from 40% to 12% moisture produces an evaporation duty around 2.85 tonnes of water per hour. The 3.5-tonne/hour dryer and 4.8 MW thermal input basis provide room above this reference.

The crop straw wood pelletizing plant in Chile has a 900 kW connected electrical basis across the straw equipment, grinder, two 250 kW pellet drives and auxiliaries. An electricity allowance around 1.8 GWh/year corresponds to approximately 90 kWh per tonne. Actual demand follows the material and preparation sequence.

Staffing provides five people per shift plus four shared quality, maintenance and administrative roles. Water provision covers welfare, selected cleaning and the approved utility arrangement. Enclosed handling and extraction control routine dust around dry stock and preparation points.

Keep Dry Product Separate from Incoming Dust

Extraction serves straw preparation, grinding, transfer and grading. Enclosed conveyors keep routine spillage contained, while cleaning doors allow retained material to be removed between incompatible production campaigns.

The crop straw wood pelletizing plant in Chile uses identified compatible fines for controlled return. Contaminated sweepings, foreign objects and unsuitable residues remain outside the product route.

Dryer and heat-source protection follow the selected installation and material assessment. Exhaust treatment, fire access and equipment isolation are included in the local site design, with installation checks against the applicable performance and operating requirements.

Equipment Cost and Total Project Investment

Investment item	Budget
Equipment cost	USD 385,000
Total project investment	USD 795,000

The equipment budget covers straw preparation, drying and heat supply, fine grinding, two pellet mills, cooling, grading, conveying, packing, extraction and controls. The project total also allows for freight, installation, foundations, electrical and utility work, the selected workshop extension and adaptation, commissioning and contingency.

The crop straw wood pelletizing plant in Chile uses the existing 800 m² building within an approximately 2,600 m² covered allocation. Processing uses 1,000 m², raw material and receiving 900 m², finished stock 500 m² and services 200 m². Yard and seasonal storage access follow the customer’s site drawings.

Land purchase, major upstream grid reinforcement and recoverable taxes are outside this basis. The stated project scope includes the selected workshop extension, allowing the customer to review machinery and site preparation together.

Delivery to the Chilean Processing Site

The booked sea gateway and onward transport route follow cargo dimensions, handling availability and site access. Heavy mill and dryer assemblies carry lifting information; smaller components are grouped by installation area.

The customer prepares unloading surfaces, foundations, workshop openings and connection points before equipment arrival. Assembly links the dry bypass and wet route to common preparation, then to the two mills and the finishing arrangement.

Questions that Define the Drying Bypass

Can every dry material go directly to the presses?

Drying suitability and particle suitability are separate checks. A dry coarse or contaminated material still needs the relevant preparation or rejection decision.

What happens when the wet fraction exceeds the sizing basis?

Operators review the water load and usable feed rate. The crop straw wood pelletizing plant in Chile keeps dryer discharge within the selected condition before maintaining the forming rate.

Can one mill run while the other is serviced?

Partial production is assessed at the available unit’s duty. The combined eight-tonne rating requires both matched mills and their supporting stages.
