A Uruguayan bio-input project is moving toward commercial-scale production with a planned 2 t/h line designed to convert suitable low-value sheep wool into compact agricultural pellets.

This is one of the more specialized residue-utilization routes in the current RICHI news portfolio.

Uruguay has a major sheep and wool sector, giving the project a direct raw-material connection.

The customer is evaluating lower-value wool that is difficult to place into higher-value textile channels and wants to manufacture a compact agricultural product rather than continue handling the material only as loose fiber.

Wool Requires a Dedicated Preparation Route

Low-value wool is not handled like compost powder.

Fibers are light, elastic and prone to entanglement.

The preparation section therefore needs controlled feeding and cutting or size reduction before pellet formation.

Material cleanliness also matters.

Foreign objects and unsuitable contamination must be removed before processing.

Depending on incoming wool condition, drying or moisture adjustment may also be required.

Loose wool also has extremely different volumetric behavior from grain, sawdust or fertilizer powder.

This means conveyors, feed hoppers and buffer capacity must be selected from actual fiber behavior rather than tonnes per hour alone.

2 T/H Is Already a Commercial Scale for This Product

The target is not a 10–20 t/h commodity fertilizer factory.

A wool-based soil product is a relatively specialized bio-input, so a 2 t/h commercial production class allows the customer to manufacture meaningful volume while retaining product flexibility.

At 2 t/h, even a single eight-hour operating shift can produce a significant daily quantity for regional agricultural and horticultural distribution.

The organic fertilizer production project‘s economics therefore depend more on raw-material sourcing, product value, packaging and market development than simply maximizing hourly output.

Pellet Specification Will Follow Field Use

The planned pellets are significantly different from conventional compost fertilizer granules.

Pellet diameter and length will be finalized through product trials according to field application and packaging requirements.

A very small pellet may increase processing energy and create unnecessary fines, while an excessively large pellet may be less convenient for some horticultural applications.

The customer is therefore testing product size as an agronomic and commercial parameter rather than adopting a standard biomass or feed pellet specification.

Full Processing Concept

The current production concept is:

wool receiving and sorting → fiber cutting/preparation → controlled moisture adjustment → buffer feeding → pelletizing → cooling/stabilization → screening → packing.

The exact cutting stage is particularly important.

Long fibers need to be reduced sufficiently to feed the pelletizing system without wrapping or bridging, but unnecessary pulverization is not the objective.

A controlled fibrous feed is more relevant than turning wool into powder.

Raw Material Sorting Protects the Product

Not all low-value wool is automatically suitable.

Foreign material, excessive contamination and unsuitable non-wool waste need to be separated.

The customer is therefore planning a receiving and inspection area before the mechanical production line.

Different wool grades can also have different fiber length, dirt content and moisture, affecting feeding and product consistency.

This front-end classification helps the plant reduce unexpected variation at the pelletizing stage.

Packaging Is More Diverse Than Conventional Fertilizer

The customer expects retail horticultural packs, nursery/farm bags and larger commercial formats rather than one standardized 50 kg fertilizer sack.

Small garden-market packs can carry higher product value per tonne but require much more packaging activity.

Farm and nursery buyers may prefer larger bags.

The organic fertilizer production line therefore leaves room for several packaging routes rather than designing the entire plant around one bagging speed.

Finished product must be sufficiently cooled and stabilized before entering sealed packaging.

No Invented Wool Blend Is Required

If other organic ingredients are ever incorporated, their compatibility would need separate formulation tests.

RICHI is not inventing a wool-compost blend merely to complicate the process.

The initial project is commercially interesting precisely because it develops a distinct use for low-value wool.

If later products contain other materials, the mixing and feeding system can be reviewed based on the actual formula.

The Customer Is Buying More Than Densification

Pelletizing can reduce the volume occupied by loose wool, making storage and distribution easier.

It also converts an irregular fiber stream into a more standardized commercial form.

However, RICHI Machinery does not claim that mechanical pelletizing alone determines fertilizer performance.

Product nutrient release, agronomic effects and application recommendations remain matters for the customer’s technical and regulatory program.

RICHI’s role is the mechanical processing system.

The project opens high-value searches including wool pellet fertilizer machine, waste sheep wool pellet production line, wool biofertilizer manufacturing equipment, sheep wool recycling plant, slow-release wool fertilizer pellet plant, horticultural wool pellet machinery, and 2 t/h wool recycling line Uruguay.

Final commercial engineering is now focused on fiber preparation, consistent feeding and a packaging arrangement capable of serving both horticultural and agricultural customers.
