Humic acid organic fertilizer granulation production line

Humic acid, known for its high organic matter content and ability to improve soil structure and nutrient absorption, is widely used in organic and biofertilizer production. However, humic acid in its powder form is difficult to store, transport, and apply. That’s why granulating humic acid into uniform pellets is essential for commercial fertilizer production.

At Gofine Machine, we offer a complete humic acid organic fertilizer granulation production line, designed specifically for processing humic acid, fulvic acid, and other organic materials into high-quality, round fertilizer granules.

Build a Profitable Humic Acid Organic Fertilizer Plant with Our Granulation Solutions.

What Is a Humic Acid Granulation Production Line?

It’s a set of machines that transforms humic acid powder and other organic materials into granular organic fertilizer, through processes like mixing, granulating, drying, screening, and packing.

Our production lines are widely used in:

Commercial humic acid fertilizer plants

Organic compost pellet production

Soil conditioner pellet projects

Biofertilizer factories with humate additives

Suitable Raw Materials

Humic acid powder

Fulvic acid

Potassium humate

Leonardite / lignite

Compost (manure, straw, kitchen waste)

Amino acids, seaweed extract, microbial agents (optional)

Recommended Granulation Machines

Humic acid production line process flow

A humic acid organic fertilizer granulation production line typically involves these steps:

Raw Material Preparation: Crushing and grinding raw materials like peat, lignite, or compost to increase surface area.

Composting/Fermentation: Promoting the decomposition of organic materials to produce humic acid using compost turners and humidity control equipment.

Mixing: Combining the compost with other organic or mineral nutrients, and a binder like bentonite or humic acid.

Granulation: Forming granules using a disc granulator, rotary drum granulator, or new type organic fertilizer granulator.

Drying: Reducing moisture content in the granules using a rotary dryer to improve storage stability.

Cooling: Cooling the dried granules with a rotary cooler.

Screening: Separating granules by size using a rotary screen to ensure product uniformity.

Packaging: Packaging the finished humic acid organic fertilizer for distribution.
