Features of the Bio-Organic Fertilizer Production Line

fertilizer granulator Aug 19, 2025

Based on the core principle of “transforming waste into treasure,” the bio-organic fertilizer production line has established a unique production system that differentiates it from traditional chemical fertilizers and has become a key force in promoting the green transformation of agriculture. Its core advantage lies in transforming agricultural waste into functional fertilizers rich in active bacterial communities, achieving both ecological and economic benefits.

A notable feature is its diverse raw material system. The production line can process a variety of organic wastes, including livestock and poultry manure, crop straw, and food waste. Through pretreatment processes such as crushing and mixing, the carbon-nitrogen ratio of each material is adjusted to an optimal range for fermentation. For example, mixing chicken manure with corn straw in a specific ratio not only balances the composting rate of high-nitrogen raw materials, but also utilizes straw fiber to improve fertilizer permeability and enhance fermentation efficiency.

Intelligent control of the fermentation process is the core technology. It utilizes trough-type turning and constant-temperature fermentation technology. Sensors monitor the temperature, humidity, and oxygen content of the compost in real time. When the temperature is too high, the turning and turning system is activated to ensure that the thermophilic bacteria thrive within the optimal range. This precise control significantly shortens the material composting cycle and completely eliminates pathogens and weed seeds, achieving harmless treatment.

The functional complexity of the finished products of the biological organic fertilizer production line forms market competitiveness. After secondary aging and low-temperature drying, the finished product not only retains rich organic matter but also contains active functional bacteria such as phosphate- and potassium-solubilizing bacteria and Bacillus subtilis. Field trials have shown that continuous application of bio-organic fertilizer can increase soil organic matter content, reduce the use of chemical pesticides in greenhouse vegetable cultivation, and improve crop quality.

This “waste-resource-product” closed-loop model not only addresses agricultural non-point source pollution but also provides a natural solution for soil remediation. Driven by policies to reduce the use of chemical fertilizers and increase their efficiency, bio-organic fertilizer production lines are becoming a crucial link between ecological protection and food security, opening up new paths for sustainable agricultural development.

How Is NPK Fertilizer Made? The Fascinating Process!

fertilizer granulator Aug 19, 2025

In modern agriculture, the NPK fertilizer manufacturing process represents a perfect marriage of science and engineering. This intricate yet efficient production method combines nitrogen (N), phosphorus (P), and potassium (K) into balanced plant nutrition.

Raw Material Preparation: The First Step in NPK Production

The NPK compound fertilizer production process begins with meticulous raw material screening. Various base fertilizers are separately sieved, then crushed and screened again. The screened materials are fed into corresponding hoppers. This preprocessing ensures uniformity and reactivity of materials for subsequent NPK manufacturing stages.

Precise Formulation: The Heart of Compound Fertilizer Production

On the NPK production production line, each base fertilizer is precisely measured and conveyed from individual hoppers to a mixing hopper. Simultaneously, recycled materials join the base fertilizers through lifting equipment. During transportation, initial mixing occurs. The blended materials are then fed into the granulator at controlled rates.

The Granulation Magic: Pivotal Stage in NPK Fertilizer Production

The granulator stands as the most critical equipment in NPK fertilizer manufacturing. As materials enter the rotating drum granulator, saturated steam introduced beneath the material bed performs dual functions – heating and moistening the mixture. When necessary, water or fertilizer solution is sprayed to maintain optimal moisture for granulation.

Featuring special rubber or acid-resistant stainless steel linings, the drum granulator facilitates particle formation through friction and compression. During NPK production, steam, ammonia gas, phosphoric acid, nitrogen solutions, or ammonium phosphate slurry work synergistically to create granules through chemical and mechanical action.

Refinement: From Granules to Finished Product

Freshly formed NPK fertilizer granules proceed to drying, followed by screening, cooling, packaging, and storage. Off-spec particles are crushed and recycled with screen undersize materials back into the NPK manufacturing process. This closed-loop design maximizes material utilization while ensuring consistent product quality.

The entire NPK compound fertilizer production process embodies modern industrial precision and circular economy principles. Each step from raw materials to finished product undergoes meticulous design and strict control, ultimately delivering efficient, balanced nutrition solutions for modern agriculture.

4. Adjust the feed rate: By adjusting the opening size of the feed hopper or the feed speed, the amount of material entering the conveyor belt can be controlled, thereby adjusting the conveying capacity. Use an adjustable roller assembly The rollers in the adjustable roller assembly can be set at an angle, and the material gathers in the middle of the conveyor belt to prevent spillage.

5. Automatic control: Use the coal inspection modules set at intervals to determine the amount of coal transported on the belt conveyor, so as to accurately control the speed of the previous belt conveyor. At the same time, use the speed sensor to collect whether the speed of the previous belt conveyor after speed regulation is accurately adjusted. In abnormal cases, use the anti-slip protection device to terminate the operation of the belt conveyor, realize the function of controlling the speed of the belt conveyor according to the amount of coal, and reasonably consume electricity and material resources.

Through the above methods, the conveying capacity of the belt conveyor can be effectively adjusted to meet the production needs of different organic fertilizer production lines.

Precautions for Using a Compost Turning Machine

fertilizer granulator Aug 19, 2025

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?

fertilizer granulator Aug 18, 2025

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.  

What are the main components of an organic fertilizer production line?

fertilizer granulator Aug 18, 2025

Those familiar with organic fertilizer production lines can generally identify their components, but for those new to the industry, this may seem a bit vague. Today, Zhengzhou Huaqiang Heavy Industry will share with you the components of an organic fertilizer production line.
The crushing section of an organic fertilizer production line. Given the diversity of user raw materials, our organic fertilizer production line equipment is designed with a crushing section. During the equipment sales process, we found that many users use relatively dry chicken manure or pig manure as raw materials, and some even mix in other raw materials to reduce organic fertilizer production costs. Raw materials with excessively large particle sizes cannot be directly granulated. Therefore, before granulation, the raw materials must be crushed to achieve the desired granulation effect before they can be fed into the organic fertilizer granulator. Of course, for users with sufficiently fine raw materials, this step can be omitted when designing organic fertilizer equipment.
The granulator section of an organic fertilizer production line is the core component of the equipment, making it an essential component. The model of granulator to be selected depends on the user’s production volume. The drying section of the organic fertilizer production line. The granulation process requires that the material humidity be kept below 25%. Therefore, raw materials with an initial humidity above 25% should first enter the drying process, and then enter the granulation process after the dried material reaches the required humidity. Of course, users with sufficient material humidity can omit this step when designing organic fertilizer equipment.
In other parts of the organic fertilizer production line, after the pelletizer completes the processing, it is conveyed by a belt conveyor to a ball shaping machine for shaping, achieving a perfectly spherical shape and forming organic fertilizer granules. For users who require it, we can design a final packaging process to directly package the final product, thus achieving perfect automation of the entire fertilizer granulation process.
