Why roller granulator is the best choice for ammonium sulfate granulation?

In the fertilizer industry, ammonium sulfate is a common and important nitrogen fertilizer widely used in agriculture to provide plants with the necessary nutrients. In the process of ammonium sulfate granule production, the selection of suitable granulation equipment is crucial. In recent years, roller pelletizer becomes the preferred equipment for ammonium sulfate pelletizing due to its efficiency, energy efficiency and cost-effectiveness. In this article, we will discuss why roller granulator is the best choice for ammonium sulfate granulation.

High production efficiency and quality pellets

The roller pelletizer adopts advanced double roller technology, so that under the influence of high pressure between the rollers, the ammonium sulfate powder is compressed into pellets. This process not only ensures the uniformity and density of the granules, but also greatly improves the production efficiency. Compared with other granulation methods, the roller granulator has a higher degree of granule formation, reducing the amount of return material and improving overall production efficiency.

Energy efficiency and environmental friendliness

The energy intensity of the roller granulator is relatively low due to the high efficiency of its mechanical transmission. In today’s industry, reducing energy consumption is the key to lower production costs and reduced environmental impact. No binders or significant amounts of thermal energy need to be added during the production process of the roll granulator, making the entire granulation process more environmentally friendly and energy efficient.

Simple operation and easy maintenance

The roller pelletizer has a simple design and is easy to operate. This means that employees can quickly learn the basics of operating the equipment, reducing training time and labor costs. In addition, the modular design makes it easy to maintain the equipment, reducing repair time and costs, thus improving equipment availability and production efficiency.

High adaptability

The roller granulator is not only suitable for granulating ammonium sulfate, but also for other powdered materials such as urea, ammonium bicarbonate, ammonium chloride and others. This multi-functional adaptability makes this equipment more attractive to fertilizer enterprises, as it can be flexibly adjusted to meet different production needs.

Cost and effectiveness

When comprehensively evaluating equipment purchase, operation, maintenance and energy consumption, the overall cost and efficiency of the roller granulator is markedly superior to other types of granulation equipment. Its high granulation efficiency and low operating costs make it an important tool to reduce production costs and improve competitiveness in the market.

Working Principle of Roller Pelletizer

The working principle of the roller granulator is: the powder material is fed evenly into the two relative rotating rollers through the feeding system, the surface of the rollers is designed with a specific shape of the groove (such as semi-circular or bar), during the rotation process, the pressure is exerted on the material, so that it is compressed and filled with molding inside the groove, when the material rotates with the rollers to the gap, the molded particles fall off from the surface of the rollers due to the effect of gravity or the scraper to complete the granulation process, the shape and size of the particles are determined by the geometric structure of the roller groove and process parameters (such as roller pressure, speed, material moisture, etc.) together. When the material rotates to the gap with the roller, the molded particles fall off from the surface of the roller by gravity or the action of the scraper, and the granulation process is completed. The shape and size of the particles are determined by the geometrical structure of the groove of the roller and the parameters of the process (such as the pressure of the roller, the rotating speed, the moisture of the material, etc).

Characteristics of Roller Pelletizer

Advantages
Simple structure, convenient operation: the equipment is compact, low maintenance cost, suitable for small and medium scale production.
High particle density: through extrusion molding, the particle strength is high, not easy to break.
Lower energy consumption: compared with spray drying and other processes, roll granulator energy consumption is significantly reduced.
Wide range of application: it can handle many kinds of powdery materials, such as ammonium sulfate, ammonium chloride, compound fertilizer, organic fertilizer and so on.

Limitations
Particle shape limitation: usually can only produce cylindrical or oblate spherical particles, it is difficult to realize the complex shape.
Sensitive to the moisture of the material: too high a moisture content of the material can easily lead to sticky rollers, too low is difficult to mold, need to strictly control the moisture content (generally 10%-15%).
Relatively low production capacity: the capacity of a single machine is usually 1-5 tons / hour, suitable for small and medium-sized production, large-scale production requires more than one parallel connection.

Thus, roller granulator becomes the best choice for ammonium sulfate granulation due to its many advantages such as high efficiency, energy efficiency, environmental friendliness, easy operation and high adaptability. With the development of technology, we can safely assume that the roller granulator will play an even more important role in the production of ammonium sulfate and other fertilizers in the future, providing agricultural production with better products.
