What is dry granulation?

If you make the powder of the materials form into little pellets by any means, we call this process granulation. Dry granulation machine works without any liquid involved, that include those adhesives and moisturizers, such as water, alcohol, etc.. The dry granulation mainly depends on physical force of the machines to process the materials. The great compaction or compression force provided by the mechanisms can make the material particles stick together with each other, the agglomerations are stable and steady, with good appearance and flowability. Because there are no chemical reactions happening, the pellet products are suitable for transporting and storage. High quality dry granulation equipment will make dry granulation procedures much more easier and efficient, some granulators manufactured by Shunxin heavy industry machinery can serve this purpose nice and well, those are double roller granulators y flat die pelletizers, they are of high quality, durability and reliability.

Where exactly can you use dry granulation technique?

1. Fertilizer granulation

Because dry granulation machine can improve the work efficiency, lower the investments, and improve the nutritional value of the pellet products in some way, so it is very popular and widely used in fertilizer granules making industry. You can use Shunxin dry granulation roller compactor or flat mold granulator to produce organic and compound fertilizer pellets of high standards with little cost.

2. Medicine granulation

Dry granulation is important in the production of some tablets and capsules. It can make the process much more simple, thus save a lot of time and energy, so it is almost irreplaceable in the pharmaceutical industry. Those tablets and capsules can be riboflavin, antibiotics, lactose, etc..

3. Chemical granulation

Similar to the medicine granulation, dry granulation is also crucial in chemical industry. You can use Shunxin double roller press granulator to make pellets or capsules out of some solid chemicals.

4. Livestock feed granulation

Because the mold of Shunxin flat die extrusion granulator can be changed with different holes on it, you can use it to produce many sizes and shapes of feed pellets via dry granulation. These feeds are suitable for many farm animals, como chickens, ducks, pigs, cattle, sheep, rabbits, fish, and so on.

5. Food granulation

Similar to feed granulation, but with stricter standards for materials formulas and production sanitation. The most common products of food dry granulation are nutrient supplements.

Why Shunxin company can provide you with high quality dry granulation machine?

The quality of a dry granulation machine is the key property during the process. Shunxin maquinaria de la industria pesada can provide you with such machines. We have dedicated our technology and resources to research and develop our products for over thirty years. We are the top manufacturer of the fertilizer making equipment in China. Our dry granulation equipment is of simple operation, high work efficiency and low investment. The machine parts all work in the completely sealed shell, no dust pollution during the granulation. Those parts that can directly contact the raw materials are carefully sealed, so no lubricating oil would be mixed with the materials. You can dismantle these parts, so you can clean them conveniently. The extrusion rollers of the granulators are made by special materials. They are of rational structure, high toughness and hardness. They can endure heavy-duty work and resist wear or corrosion.

Why do we need dry granulation machine to produce pellets?

You can operate dry granulation under normal temperature with low moisture materials. That means the whole process goes almost without water. So the moisture sensitive materials will preserve their functionality after the granulation. It is very important to certain fertilizers, medicines and chemicals. You can easily process them with dry granulation, but it will be hard to do this by other means. Normally, you should pair a rotary drum dryer with granulators to dry out the pellet products. It means you need to heat the products up. Some temperature sensitive materials might change their properties during this process. But dry granulation will make sure those temperature sensitive materials will remain the same after the granulation, they will function as your expectation.

What are the advantages of dry granulation?

As a later developed but widely used granulation technique, there are many merits about dry granulation process. It will raise your overall production efficiency, and lower the cost of operation and maintenance.

• Shunxin dry granulators requires less space compared to other granulators, but their production capacity never shrink with their sizes. The required setup space of a machine is always a major issue you need to consider, now you can use the some room with more dry granulators, that means improved total production.
• Dry granulation process is suitable for both mass production or batch granulation. No matter your fertilizer plant is big or small, Shunxin dry granulators can always come in handy.
• Shunxin dry pelletizers can guarantee the high quality of their products. The extrusion mechanism of our granulators are steady, and the dry granulation techniques are reliable. The granule products are of uniform size, and higher intensity than the products of other granulators.
• Dry granulation is a kind of cost-effective granulating method. Since there is no binder during the process, and no drying after the production. You can assume it will save you much energy and time.
• The pellet products created by dry granulation are more soluble, since they possess less water content. You can easily resolve them during application.

Is dry granulation machine an all-purpose way to make pellets?

Of course dry granulation is not omnipotent, it has several disadvantages that you should know about.

1. You must pre-prepare the materials before granulation. The materials need to be fully fermented and shredded. Shunxin heavy industry machinery has developed corresponding equipment for this problem. You can use our fertilizer compost machine and crushing machine to get the job done, they are also reliable and durable.
2. If the dry granulation machine is not good enough, you will end up with a lot of powder and dust spreading all over the place during the process. But if you are using Shunxin dry granulators, this will no longer a bothering problem. Our elaborate design will ensure there is no air pollution caused by the process.
3. Because the granule products of the dry granulation are made by the extrusion or compression of the machines, they are not perfectly round. For that, you can use Shunxin fertilizer pellet polishing machine to make the granules look more beautiful and spherical.
