Written by fertilizer production line on . Leave a comment

In the organic fertilizer production process, the innovative 2-in-1 granulator serves as the core equipment that transforms decomposed organic matter into uniform fertilizer pellets. This advanced machine combines crushing and granulation functions, efficiently processing various organic wastes – including animal manure, agricultural residues, and food waste – into dense, spherical granules with optimal moisture content (typically 25-35%).

The granulation process begins with pre-treated organic materials entering the rotating drum, where specialized agitators and mechanical forces create the necessary friction and pressure for particle formation. The machine’s dual-action design ensures proper particle size distribution (2-4mm) while maintaining the organic matter’s nutrient integrity. This critical stage bridges the gap between raw material preparation and final product refinement in the complete organic fertilizer production process.

1. The Magical Journey from Waste to Fertilizer

Raw Material Preparation: Fermented organic materials are “chewed” by the crusher into fine 40-60 mesh powder, just like sifting flour before baking a cake. Moisture is precisely controlled within the “golden range” of 25%-35%.

Mixing Magic: In the mixing chamber – this “big bowl”, raw materials and no more than 3% binder dance a 5-10 minute “waltz” until every particle is coated with an even “coat”.

Granulation Transformation: Depending on material characteristics, the equipment performs different “magic” – sticky materials use “tooth stirring magic” for agglomeration, while fibrous materials use “roller pressing magic” for forceful forming, ultimately producing perfect 1-6 mm pellets.

Did you know? Unqualified pellets after screening are sent back to “magic school” for retraining, achieving over 95% material utilization rate, truly realizing “every pellet finds its home”.

2. The Unique Skills of 2-in-1 Granulator

Precautions for Using a Compost Turning Machine

Written by fertilizer production line on . Leave a comment

As a core piece of equipment for material fermentation in an organic fertilizer production line, the proper use of a compost turning machine directly impacts production safety and fermentation efficiency. During daily operation, equipment inspection and parameter adjustment must be thoroughly monitored to ensure maximum performance.

A thorough pre-startup inspection is the first line of defense for safe operation. Check the tracks or running wheels for deviation and bolt connections for looseness. In particular, check for breakage or excessive wear on the turning blade assembly to prevent blades from falling off and causing damage to the equipment during operation. Also, clear the fermentation tank of hard objects such as rocks and metal to prevent them from becoming entangled in the turning mechanism and causing it to jam. Electrical system inspection is essential. Ensure cables are intact and grounding is reliable. Install a waterproof cover during rainy weather to prevent electrical leakage.

Parameter adjustment during operation is crucial for ensuring fermentation quality. Dynamically adjust the turning depth and frequency based on the material’s characteristics: High-protein materials like fresh livestock and poultry manure require more frequent turning to ensure ventilation and oxygen supply to prevent anaerobic decay. Crude fiber materials like straw can be turned more deeply to promote even mixing. The turning speed should be matched to the material’s moisture content. If the moisture content is too high, slow the turning speed to reduce clumping. Dry materials can be turned faster to improve efficiency.

Post-downtime maintenance determines the lifespan of the equipment.After each run, clean the blades and trough to prevent caking and compaction, which increases the load at the next start-up. Regularly lubricate bearings, chains, and other transmission components, and promptly replace severely worn parts. When the equipment is idle for extended periods, it should be stored in a dry location, the blades should be coated with anti-rust oil, and the electrical system should be disconnected from the power supply and dust-proofed.

Proper operation of a compost turning machine is not only essential for ensuring production safety, but also a scientific approach to improving fermentation efficiency and reducing operational costs, laying a solid foundation for the resource utilization of organic waste.

What is the production process of an organic fertilizer production line?

Written by fertilizer production line on . Leave a comment

In terms of equipment, an organic fertilizer production line requires a fermentation compost turner, fertilizer crusher, fertilizer mixer, fertilizer granulator, fertilizer dryer, fertilizer cooler, fertilizer screening machine, fertilizer packaging machine, fertilizer conveyor, and fertilizer coating machine.

The raw materials used in organic fertilizer production vary widely, including livestock and poultry manure, municipal sewage sludge, and animal and plant residues. These raw materials are rich in organic matter, nitrogen, phosphorus, potassium, and other nutrients, providing essential nutrients for crop growth and are available at low prices.

How an organic fertilizer production line works:

Organic fertilizer processing primarily involves collecting, crushing, and mixing the raw materials. The raw materials are then mixed according to the desired formula, and the moisture content and carbon-nitrogen ratio are adjusted before the fermentation process begins.

Fermentation compost turning machines: Assist in turning the compost during the fermentation process, provide sufficient oxygen, and control the temperature to ensure uniform and thorough fermentation.

Fertilizer mixers: If the size and state of the fermented material are inconsistent, a semi-wet material grinder can be used for fine grinding.

Fertilizer Granulator: The crushed material is processed into uniformly sized organic fertilizer granules by the organic fertilizer granulator.

Fertilizer Cooler: After granulation, the organic fertilizer still contains approximately 30% moisture. To increase its strength, the granules need to be cooled for later storage and transportation.

Fertilizer Screening Machine: After granulation, a small number of unqualified granules, some too large and some too small, will be produced. The fertilizer screening machine is used to separate these granules. Oversized granules are returned to the fertilizer crusher, while undersized granules are returned to the fertilizer granulator for regranulation. Qualified granules are then sent to the automatic packaging machine.

Fertilizer Packaging Machine: The finished organic fertilizer granules are packaged by the automatic packaging machine, completing the entire process.

It should be noted that the above configuration is for a typical organic fertilizer production line and may not be suitable for all situations. In actual production applications, different manufacturers may have different requirements regarding site and raw materials, and adjustments may be required based on actual needs.
