As global agriculture moves toward sustainability, the demand for organic fertilizers made from compost and animal waste is rapidly growing. With the right fertilizer production equipment, you can turn livestock manure, compost, and other organic waste into high-value fertilizer granules for local farms or commercial markets.

We provide complete compost/manure fertilizer granule plant solutions — from raw material fermentation to final packaging.

What Is a Compost / Manure Fertilizer Granule Plant?

A compost or manure fertilizer granule plant is a production system designed to convert organic waste such as cow dung, chicken manure, pig slurry, crop straw, food waste, and sewage sludge into granular fertilizers that are easy to store, transport, and apply.

Here's a breakdown of the key aspects:

Purpose: To convert organic waste materials, such as animal manure and compost, into a nutrient-rich, easy-to-handle, and marketable granular fertilizer. This process adds value to waste products, promotes sustainable agriculture, and reduces reliance on synthetic fertilizers.

Raw Materials: The primary raw materials are composted organic wastes, often animal manure (cow dung, chicken manure, pig manure). Other organic materials like crop residues, food waste, and other compostable materials can also be included.

Production Process: The typical production process involves several stages:

Composting/Fermentation: This initial step is crucial for stabilizing the organic matter, reducing odors, killing pathogens, and converting nutrients into plant-available forms. This often involves using compost turners or specialized fermentation tanks to ensure proper aeration and temperature control.

Crushing/Pulverizing: The composted material is crushed to eliminate caking and create a fine powder.

Mixing: The pulverized compost is mixed with other ingredients or additives to adjust the nutrient content and improve fertilizer properties.

Granulation: The mixed material is then granulated to form uniform pellets. Common granulation methods include wet granulation (using disc granulators or rotary drum granulators) and dry granulation (using extrusion granulators).

Drying and Cooling (for wet granulation): If wet granulation is used, the granules are dried to remove excess moisture and then cooled to prevent caking.

Screening: The granules are screened to separate the desired size range from oversized or undersized particles. Oversized particles are crushed and returned to the process, while undersized particles are recycled as input material.

Coating (Optional): The granules may be coated to improve handling characteristics, control nutrient release, or add additional nutrients.

Packaging: The finished granular fertilizer is weighed and packaged into bags for storage, transport, and sale.
