The Powder Granulation Process: Step by Step

1. Raymond Mill System: The journey begins with the meticulous preparation of the powder. Whether mineral or chemical in nature, the powder undergoes precision milling via the raymond mill system, guaranteeing a consistent and top-tier powder output.

2. Double Shaft Mixer: The mixed powder encounters the double shaft mixer, where an assortment of additives can be seamlessly integrated to augment the granules’ properties. The mixer ensures the homogeneous distribution of these additives throughout the powder.

3. Disc Feeders: Regulating the material flow into the double roller extrusion granulator, the disc feeders play a pivotal role. Here, under immense pressure, the powder undergoes compression and morphs into granules, thanks to the collaborative efforts of multiple rollers.

4. Rotary Screener: Post-granulation, the granules undergo scrutiny via the rotary screener, which meticulously segregates oversized or undersized particles, allowing only the epitome of granules to progress to the subsequent phase.

5. Coating Machine (Optional): For those desiring an additional layer of refinement, the granules can undergo coating via the coating machine. This optional step confers benefits such as enhanced flowability, aesthetic enhancement, or moisture protection.

6. Double Bucket Granules Packing Scale: The culmination of the process sees the granules meticulously packed and weighed utilizing the double bucket granules packing scale, ensuring precision and consistency in packaging.

Conclusion

The advent of the 30 t/h granulation production line heralds a new era in granulation technology, characterized by unparalleled efficiency and quality. With its advanced features, notably the double roller extrusion granulator, this production line caters to a myriad of industries, seamlessly transforming raw materials into marketable granular products. Backed by Yushunxin’s commitment to innovation and reliability, the roller press granulation production line emerges as a veritable game-changer in the industry.

Learning The Working Process Of A Dry Granulation Machine

Posted on by grxksr

Dry granulation machine implements a granulation technique that never requires the addition of water or binder when granulating. In addition, you don’t have to dry the finished pellets by using the drying machine. Generally speaking, this technique makes use of the crystal water available in the raw materials, which shapes them by strong extrusion.

So, the dry granulation equipment combines compressing, crushing, and granulating. And to some extent, this equipment makes up for the deficiency that comes with the wet granulation method. This is in terms of the requirements of raw materials and the granulating process.

What Entails the Dry Granulation Process?

Typically, the dry granulation machine implements the dry granulation process to create fertilizer granules. It’s also applicable to creating pellets without using liquid solutions. This is mainly because the granules might be sensitive to the heat or moisture. So, it shapes the granules by simply pressing on the materials.

It’s also worth noting that you could use a double roller press machine to create fertilizers through dry granulation. Usually, the counter-rotating rollers offer a strong extrusion force that helps in pressing materials into relatively large tablets. Inside the machine, it consists of a unique structure that plays a vital role in crushing these tablets and making them into pellets.

What Are the Dry Granulation Steps?

In general, we can divide the entire granulation process into three steps. These include the preparation of materials, feeding into the equipment uniformly, and granulation. Let’s take a look.

– Preparation of materials. When it comes to dry granulation, the raw materials should contain crystal water, or perhaps the moisture content is approximately 5%. For granulating, you’d instead use the 80 mesh to 300 mesh materials. When it’s too crude, the finished pellets might be uneven. On the other hand, for the fine powder, it is quite challenging to granulate. As a result, you must prepare appropriate raw materials before starting dry granulation.

– Feeding uniformly. When you are feeding materials into your dry type granulation machines, continue feeding uniformly. This is very important to the entire process. The roller sheets are usually easy-to-damage parts. That means that uniform feeding might prolong the service life of those roller sheets. What’s more, they will also play a significant role in improving the granulation rate.

– Granulation. In this stage, the counter-rotating roller sheets will basically press the materials you fed into large tablets by making use of strong extrusion force. After that, the inner structure of your machine will crush those tablets and granulate. Lastly, the finished pellets will be discharged from the machine’s outlets.

You should know that the dry granulation process has no wastewater or gas emission. That means you won’t be causing any harm to the environment when using this piece of equipment. Are you concerned about the high prices of dry granulation facilities? Or perhaps you are looking for a professional manufacturer of fertilizer equipment? You can undoubtedly get a supply which meets your needs, whether for the profession or costs.
