2025-10-24 by organic fertilizer production line

Equipment Applicability and Production Scope

The rotary drum granulator performs most effectively in NPK production lines, particularly suitable for producing compound fertilizers. This fertilizer production machine efficiently processes various raw material combinations through drum granulation technology, making it an indispensable core component in modern NPK fertilizer production technology.

Main Raw Materials and Formula Requirements

In the NPK manufacturing process, the drum granulator primarily processes basic raw materials such as nitrogen, phosphorus, and potassium sources, including urea, ammonium sulfate, monoammonium phosphate, and potassium chloride. Unlike traditional fertilizer compaction processes, drum granulation doesn’t require high-pressure fertilizer compaction machines, instead forming granules through an agglomeration principle.

Compared to fertilizer granules compaction technology, the rotary drum granulator is more suitable for processing raw materials containing organic matter, producing fertilizer granules with a looser structure that are more easily absorbed by crops.

Detailed Production Process Flow

The complete NPK fertilizer production process begins with raw material pretreatment. During drum granulation, materials are precisely proportioned before entering the mixer to ensure uniform ingredient distribution. The material is then fed into the rotary drum granulator through a feeding device, forming granules under the rotating action of the drum.

In the fertilizer production machine system, the process parameters of the drum granulator require precise control:

· Drum rotation speed: 10-20 RPM

· Tilt angle: 2-5 degrees

· Water addition amount: Adjusted according to raw material characteristics

· Particle diameter: Adjustable between 1-6 mm

Production Requirements and Technical Advantages

The NPK production line requirements for the rotary drum granulator include controlling raw material particle size between 0.1-1 mm and achieving mixing uniformity above 95%. Advanced NPK fertilizer production technology requires precise control of binder addition during granulation to ensure appropriate particle strength.

Compared to traditional fertilizer compaction processes, the rotary drum granulator offers advantages of lower energy consumption, regular particle shape, and uniform nutrient distribution in the NPK manufacturing process, making it the preferred choice for modern fertilizer production machines.

Post-processing and Quality Assurance

In the NPK fertilizer production process, wet granules after granulation require immediate drying to reduce moisture content below 10%. The cooling and screening stage ensures particles reach room temperature, with screening equipment separating non-conforming particles. The quality control system throughout the NPK production line ensures the excellent quality of the final product.

By optimizing drum granulation process parameters, NPK fertilizer production technology continues to advance, providing efficient and environmentally friendly fertilizer solutions for global agriculture. The innovative application of this fertilizer production machine promotes the development of the fertilizer industry toward more sustainable directions.

BB fertilizer mixers: Key equipment for ensuring uniform nutrient distribution in blended fertilizers

2025-10-24 by organic fertilizer production line

In BB fertilizer (blended fertilizer) production, the BB fertilizer mixer is a key piece of equipment that determines product quality. Its core function is to evenly blend multiple raw materials of varying density and particle size into a nutrient-consistent fertilizer, directly impacting subsequent fertilization effectiveness.

In terms of equipment structure, mainstream BB fertilizer mixers mostly adopt a closed-cylinder design with an internal mixing assembly. The cylinder is typically positioned horizontally, with the mixing assembly driven by a motor. Some BB fertilizer mixers also feature forward and reverse rotation to reduce residual material in the cylinder. The feed inlet is typically located at the top of the cylinder, and the discharge outlet at the bottom. Some models feature an observation window for easily monitoring the mixing status.

During operation, raw materials such as urea, monoammonium phosphate, and potassium chloride are introduced into the mixing cylinder according to the formulated ratio. The rotating mixing assembly propels the raw materials: the screw conveys the raw materials from both ends toward the center, the paddles shear and stir the raw materials, and the guide plates facilitate convection, ensuring full contact between raw materials with density differences of 30%-50%. The entire process does not require the addition of adhesives, and mechanical force is used to achieve “small particles filling gaps and large particles colliding with each other”, ultimately achieving a uniform mixing effect.

Fertilizer granulator machines: Adaptation strategies for different fertilizer types

2025-10-24 by organic fertilizer production line

Many fertilizer companies switch product categories based on market demand. However, if the compatibility of the fertilizer granulator machine with the fertilizer type is neglected, problems such as reduced granule quality and frequent equipment failures can occur.

For organic fertilizers (including straw and fermented manure), the key requirement is “adaptability to the fiber raw material and avoid entanglement and machine blockage.” Flat die granulators or rotary drum granulators are preferred. The vertical extrusion design of the flat die cuts long fibers, and the trapezoidal, non-slip rollers reduce fiber entanglement. Rotary drum granulators use rolling to form the granules, and the lifting plate evenly lifts the fiber material to avoid localized accumulation.

For compound fertilizers (containing phosphate rock and potassium chloride), the key requirements are “high granule hardness and transport resistance.” The high compression ratio of the ring die granulator allows hard mineral raw materials to be extruded with a compressive strength of over 15N, meeting the requirements of long-distance transportation.

For biofertilizers (containing functional microbial agents), the key principle is “low-temperature granulation to protect the activity of the agents.” A flat die granulator (chamber temperature ≤ 40°C) or a disc granulator (rolling, no high-temperature extrusion) can prevent inactivation of microbial agents.

For slow-release fertilizers (including coating materials), “smooth granules suitable for subsequent coating” are required. The rolling forming method of a rotary drum granulator produces smooth, uniformly sized granules, which prevent the coating from detaching during coating.

Windrow compost turning machines: Breaking site constraints and adapting to flexible fermentation

2025-10-23 by organic fertilizer production line

The core of aerobic fermentation of organic fertilizers lies in uniform oxygen supply and temperature-controlled composting. The site adaptability of compost turning equipment directly determines fermentation efficiency and production flexibility. Windrow compost turning machines, with their trackless mobility and all-terrain adaptability, are a perfect fit for the diverse fermentation scenarios in the fertilizer industry.

From a structural perspective, the core advantage of windrow compost turning machines lies in the synergy between their crawler chassis and flexible turning mechanism. Their wide rubber tracks provide a large contact area and low ground pressure, preventing the vehicle from getting stuck even in muddy composting areas or gravel surfaces after rain, eliminating the need for pre-leveling. The chassis’ steering system supports 360° steering, making it easy to navigate obstacles such as raw material piles and equipment around the fermentation area.

In terms of the turning mechanism, most windrow compost turning machines are equipped with double-auger or blade-type turning components, capable of turning compost up to 1.2-2 meters deep and covering compost piles up to 3-5 meters wide. During operation, the equipment slowly moves along the fermentation pile. The turning components throw the bottom material upward and disperse it to the sides, creating a “rolling up and down, mixing side to side” effect. This not only provides sufficient oxygen for aerobic bacteria but also quickly dissipates the heat generated by fermentation.

For fertilizer companies, the value of a windrow compost turning machine lies not only in its flexibility but also in its ability to accommodate multiple fermentation batches. For example, the same site can simultaneously process both a “fresh feed pile” and a “mature compost pile,” allowing the equipment to flexibly switch between different piles, resulting in fermentation efficiency improvements of over 30% compared to track-type compost turners.

Fertilizer granulators: How to adapt to the special production requirements of functional fertilizers?

2025-10-23 by organic fertilizer production line

As the fertilizer industry upgrades toward “precision and functionalization,” demand for functional fertilizers such as slow-release fertilizers, biofertilizers, and trace element compound fertilizers has surged. The production of these fertilizers places special demands on granulators, balancing functional retention and granule formation.

For slow-release fertilizer production, fertilizer granulators must meet the dual requirements of “granule formation” and subsequent coating. For example, when producing sulfur-coated slow-release fertilizers, the granulation process requires producing base granules with a smooth surface and uniform hardness. The “rolling forming” feature of a rotary drum granulator is perfectly suited for this purpose. By controlling the drum speed (8-12 rpm) and the amount of binder used, the granules are naturally rounded and smooth. Some granulators also feature a “pre-cooling section” at the discharge port to reduce the granule temperature to below 30°C, paving the way for subsequent coating and preventing the coating material from melting and becoming ineffective due to high temperatures.

For compound fertilizers containing trace elements, fertilizer granulators must address the issue of uneven trace element distribution. These fertilizers contain low concentrations of trace elements such as zinc, boron, and iron. Inhomogeneous mixing can lead to nutrient deficiencies in some granules. In this case, the low-speed extrusion design of a flat die granulator is optimal. After thoroughly mixing the trace elements with the base raw materials in a twin-shaft premixer, the low-speed rollers slowly extrude the granules into shape, minimizing material separation and ensuring a trace element content variation of ≤0.1% per granule, thus preventing functional deficiencies.

For biofertilizers, the granulator’s low-temperature performance is crucial. Flat die and disc granulators utilize a low-friction, no-high-temperature extrusion design to maintain a temperature within the granulation chamber below 40°C, ensuring the survival rate of the microbial inoculant.
