The important role of drum screener machine in NPK fertilizer production

fertilizer granulator Sep 22, 2025

As a multi-element compound fertilizer, NPK fertilizer has a complex production process and requires extremely high particle uniformity. Drum screener machine, with their precise grading capabilities, are essential key equipment in NPK fertilizer production, serving multiple stages, including raw material pretreatment, semi-finished product processing, and finished product inspection.
During the raw material pretreatment stage, drum screener machine can pre-screen these raw materials, removing impurities or large lumps of raw material that exceed particle size standards. This ensures uniform particle size before mixing, laying a solid foundation for the subsequent granulation process and avoiding uneven granulation caused by varying raw material particle sizes.

During the semi-finished product processing stage, NPK fertilizer granulation produces particles of varying sizes, which require grading using a drum screener machine. The equipment accurately separates particles that meet standards, while simultaneously sending overly coarse particles to a crushing facility for reprocessing and returning overly fine powder to the granulation process for secondary use. This significantly improves raw material utilization and reduces waste.
During the finished product inspection stage, the secondary screening of finished fertilizer ensures that the particle size of each batch of NPK fertilizer meets industry standards and market demand.
Furthermore, the equipment’s continuous operation capability meets the needs of large-scale NPK fertilizer production, seamlessly integrating with the production line and avoiding production stoppages caused by interruptions in the screening process.

fertilizer granulator Sep 19, 2025

For businesses, efficiency and convenience are crucial considerations when choosing crushing equipment, directly impacting production costs and capacity. Chain crushers excel in both these areas, making them an ideal choice for many.
In terms of efficiency, chain crushers utilize a high-speed impact and shear crushing principle. The motor drives the rotor at high speed, while the chain and hammers rapidly and forcefully impact the material, significantly reducing crushing time and improving overall production efficiency. Compared to traditional crushing equipment, they offer faster crushing speeds and can process more material per unit time, effectively meeting the needs of large-scale production. Even with large batches of medium-hard materials, they maintain stable crushing efficiency, avoiding production bottlenecks.

In terms of convenience, the equipment is designed for ease of operation and maintenance. The user interface is simple and easy to understand, with clear instructions, allowing operators to easily master the process after minimal training, lowering the operational barrier.
At the same time, the chain crusher structure is easy to maintain. For example, the openable protective door design allows direct access to the internal core components, making it convenient for internal cleaning and component inspection and replacement, reducing maintenance time and labor costs, lowering equipment failure rates, ensuring continuous and stable production, and reducing losses caused by maintenance downtime.

Tips for selecting a BB fertilizer blender to suit your production needs

fertilizer granulator Sep 15, 2025

Choosing the right BB fertilizer blender is crucial for ensuring fertilizer production efficiency and quality. This selection requires comprehensive consideration of factors such as your production scale and raw material characteristics.

First, consider the equipment’s processing capacity. Based on your company’s daily fertilizer production needs, select equipment with a corresponding processing capacity (tons/hour). Small and medium-sized enterprises can choose equipment suitable for basic production capacity, while large-scale production requires high-capacity models to avoid insufficient capacity or excessive waste.
Secondly, consider raw material compatibility. Different companies produce fertilizer raw materials with varying properties, some primarily solid particles, while others primarily powders. It’s important to confirm whether the BB fertilizer blender can efficiently handle the type of raw materials you need to mix, ensuring uniform mixing without compromising raw material properties. The equipment’s mixing uniformity is also a key indicator. By understanding the design of the equipment’s mixing mechanism (such as the blade type and mixing drum structure), you can determine whether it can meet the requirements for uniform nutrient distribution in the fertilizer, thus avoiding poor mixing that could affect product quality.

Furthermore, ease of operation and maintenance must be taken into consideration. Prioritizing BB fertilizer mixers with precise control systems and simple structures reduces operator complexity and maintenance costs. At the same time, attention should be paid to the clean design of the equipment to ensure cross-contamination of raw materials during subsequent production, thereby meeting fertilizer production quality standards.

How Does a Disc Granulator Turn Powder into Perfect Pellets?

fertilizer granulator Sep 3, 2025

The disc granulator is a cornerstone of modern fertilizer production machine technology, efficiently transforming fine powder materials into uniform, spherical pellets. Through a combination of rotational motion, liquid binding agents, and gravitational forces, this equipment creates the ideal conditions for fertilizer granules compaction and formation. As the rotating disc turns, powder particles are gradually layered and compacted into perfectly-sized pellets through a process known as accretion granulation. This method ensures optimal density, hardness, and size consistency—critical factors for effective fertilizer application and nutrient delivery.

The Art of Granulation

In modern chemical and agricultural industries, disc granulators play a vital role. This seemingly simple equipment performs the magic of transforming loose powder into uniform pellets, significantly improving material utilization efficiency and transportation convenience. But how exactly does this machine accomplish this transformation?

Core Working Principle

The essence of the disc granulator lies in its ingenious mechanical design. The main motor drives the reducer through a pulley and belt system, which then rotates the pinion gear. This pinion meshes with a large gear fixed at the end of the adjustment plate, transmitting power to the main shaft. The entire disc is mounted on this shaft, supported by the sturdy adjustment plate.

The Granulation Magic

When materials are fed into the rotating disc, the real magic begins. With the help of spray devices, powder materials gradually aggregate into uniform pellets under the combined action of centrifugal force and binding agents, much like rolling snowballs. The disc’s tilt angle and rotation speed are meticulously calibrated to ensure each pellet achieves perfect sphericity and consistent size.

Intelligent Cleaning System

To prevent material adhesion that could affect efficiency, an automatic cleaning device is ingeniously installed at the top of the disc. This thoughtful design not only ensures stable continuous production but also significantly extends the equipment’s service life. With the motor running continuously, materials can be fed uninterruptedly, enabling truly continuous mass production.

The Secret to Efficient Production

The true advantage of disc granulators lies in their perfect marriage of simple principles and precision engineering. By optimizing every rotation parameter and mechanical interaction, this equipment can operate 24/7, meeting modern industry’s demand for continuous, automated production. Whether for chemical raw materials or fertilizer production, disc granulators consistently deliver satisfactory results.

Difference between the production machines of organic fertilizer and compound fertilizer

fertilizer granulator Oct 29, 2020

The internal quality of organic fertilizer mainly depends on raw material fermentation and product formula. The key factors affecting the fermentation of organic fertilizer production process are: microorganism, carbon nitrogen ratio, carbon phosphorus ratio, water content, pH value, aeration control. If one factor is not properly controlled, the whole fermentation will be affected, resulting in incomplete fermentation of materials or long fermentation time. If the material fermentation is well formulated, the effect is better than inorganic fertilizer, and the cost is also low. It can also improve the living environment of plants and become green fertilizer. The formula of organic-inorganic compound fertilizer is different from that of inorganic fertilizer, and there are also differences in different soil and crop formulas. The organic fertilizer manufacturing process is different from that of compound fertilizer, and the fertilizer production machine is also different.

Difference of production technology between compound fertilizer and organic fertilizer

The machines required for the organic fertilizer manufacturing process is mainly divided into two parts, fermentation part and production granulation part. NPK fertilizer manufacturing process is mainly granulation processing. The granulation part of organic fertilizer is also different from that of inorganic fertilizer.
Because organic raw materials are different from inorganic raw materials, the production of inorganic raw materials can be mainly based on the formula of raw materials, which is mainly chemical reaction. If the formula is proper, the operation is skilled, the pelletizing rate is very high, and the production is relatively easy. Roller granulator is suitable for dry granulation of NPK fertilizer and disk granulator is suitable for wet granulation.
For organic fertilizer, granulation is difficult even if the raw materials are fermented well, because the characteristics of organic raw materials are light, rough, low adhesion, and a wide variety of organic raw materials. Raw materials have different characteristics, so when selecting fertilizer granulating machine, special attention should be paid, otherwise not only the output will be affected, but also the appearance of the product is not beautiful. Rotary drum granulator is generally used for granulation of organic fertilizer and compound fertilizer.

When selecting the organic fertilizer production machine, we should pay attention to the following points: output of organic fertilizer production, organic raw materials, fermentation mode, fertilizer granulator machine, mechanization degree of organic fertilizer equipment. These are key factors in purchasing equipment. In short, organic fertilizer production is a relatively complex process, but the risk is relatively small, which can bring rich profits to the enterprise.

⑦ The granulator equipment needed for fertilizer granulator system shall be set according to the raw materials and process. The pelletizer can be selected as follows: double roller granulator, organic fertilizer and compound fertilizer combined granulator, pan granulator, new type organic fertilizer granulator, flat die pellet mill, rotary drum granulator, ball shaping machine, etc.

⑧ Drying system: the organic fertilizer drying system consists of a rotary dryer and a cooler.

⑨ Screening and coating system: it is mainly completed by the roller screen, which can be equipped with primary screen and secondary screen, so that the yield is higher and the particles are better. After screening, the fertilizer coating machine can be used to ensure that the fertility is not released.

⑩ Finished product packaging system generally includes electronic quantitative packaging scale, silo, automatic sewing machine, etc. In this way, automatic and non-intermittent production of organic fertilizer equipment can be realized; the conveyor system mostly uses belt conveyors and screw conveyors.

The raw material has good comminution fineness, which is beneficial to the pelletizing processing of disc granulator machine and other equipment. During the operation of the organic fertilizer production line, considering that the high fineness of the pulverizer will produce certain dust pollution, the dust treatment of the pulverizer should also develop perfect measures to ensure that there is a good environmental condition in the production workshop and a good working environment for the operators.
In the dedusting system, the small production line can adopt the cyclone deduster series products, so as to facilitate the collection and recovery of materials. Cyclone dust collector will not produce high temperature and condensation phenomenon, and the equipment price is relatively low, which saves the equipment cost very well, and is the ideal product of proportioning dust removal system. The process of organic fertilizer production line with an annual output of 20,000 tons is more cost-effective to build a dust removal room, with better dust removal effect, high efficiency and long service life.
