The roller extrusion granulator plays an important role in compound fertilizer granulation. It can also make organic fertilizer pellets cheaply and affordably. The machine can be used to produce compound fertilizers of high, medium, and low concentrations. The reason most people have embraced it is because of its properties which make it unique. Some of these properties include its ability to consume low energy, its reasonable design, and compact structure. It has also adopted the advanced technology, which increases its efficiency in fertilizer granulation. The machine has also adopted the eugenic formula without drying and also produces fertilizer using the room temperature. It  makes use of renewable energy which is essential for sustainability.

The Working Principle.

The machine can be divided into two parts, the part that is responsible for granulation and the part that is responsible for extrusion. The purpose of extrusion is to ensure that the air between the particles is squeezed out to allow enough distance for interaction forces to act.  In the extrusion process, the dry materials are condensed into hard materials under pressure. This process makes use of the intermolecular principle. After the dry materials have been turned into hard and caky deposits, the next process that follows is the granulation which transforms the caky material into granules. This is done using the rollers. The space found between the rollers is usually adjustable such that the utilization of materials can even reach 87%. The good thing about the roller extrusion granulator is that it can operate under normal temperature and still yield a high granulation ratio.The machine alone does an excellent job when it comes to fertilizer granulation. However, you have the option to compose other granular fertilizer making machines, to create a full production line with continuous working capacity.

Benefits Of The Double Roller Extrusion Granulator.

There are several advantages of using a double roller extrusion granulator. First, you get to save energy since the raw materials of the double roller granulator are granulated under room temperature, which reduces the dry energy consumption. Since renewable energy is also used, there are no harmful gas emissions. No oil or gas is required to fire it and thus, fertilizer investors get good economic returns from little investment.

The machine is easy to use and maintain. You don’t need to be extremely skilled and for you to use the machine. It has a compact structure and a stable granulating process. It simplifies the process of making fertilizer granules through the use of intermolecular forces. You don’t even need to add a lot of additives since the process is straightforward.

It also has a reasonable structure that is lightweight and steady in rotation. Its stiffness and precision make it highly efficient. They have press rollers which are responsible for pressing the materials into different shapes and sizes. The press rollers are made in such a way that they are resistant to oxidation, corrosion, and abrasion. This allows the machine to have a long service life.

If you are thinking of investing in a double roller extrusion granulator, don’t waste any more time. It is efficient, energy-saving, easy to use, and convenient. Invest in one, and you won’t regret it.

Wet Granulation Of Organic Fertilizer

Production process of organic fertilizer employs organic waste. The elements can be acquired at small or large scale quantities depending on the public demand. The different production materials include cow dung, industrial sludge, livestock manure, and plant waste. The method of making organic fertilizer is called composting. It involves a series of processes to eliminate any risks of pollution or harm to plants. One of the methods applied here is granulation. The primary machine used is called a granulation or fertilizer pellet equipment. The procedure aims at forming the powder fertilizer into pellet-like substances. Fertilizers produced in this form are convenient in terms of storage and also usage. Also, transportation is much simpler as there is less risk of spillage, which results in losses.

The wet granulation process is efficient and convenient as it has provisions for the addition of quality enhancers. For instance, you could add some functional bacteria to make bio-organic fertilizer. It is a deep processing method aimed at giving the best output. The first raw material used in this process is water. It is a universal element ideal for all types of wet granulating devices. The addition of water is in appropriate proportions. It is necessary to prevent the granular fertilizer from becoming excessively wet. The introduction of water can also be in vapor form for efficiency. In the production of organic fertilizer production, granulation is relatively more straightforward considering the locally available materials. However, the devices used here come in different variations to suit all the raw materials available. Before making considerations, it is vital to have a full understanding of your production requirement. There is no standard device suitable for all materials. Also, production capacity is essential for you to meet your demands. If you have a large market, the rotating granulator is the best option. Other people opt for a combination of smaller deceives if they have unique needs.

Also, check the available storage space since the equipment comes in different sizes. Lastly is the cost. Having a budget can go a long way in helping you to make a decision. If you cannot manage to get a brand-new device, there is also an option of leasing or acquiring a second-hand model. Nevertheless, dealing with a wet granulation device offers you several benefits. The first and most crucial is you can control the diameter of pellets. Depending on your customer’s needs, you can adjust to either smaller or bigger sizes. It is possible by regulating the moisture content of the raw materials before the actual process. Also, the introduction of water and binders makes adhesion efficient hence resulting in minimal pollution. Compared to the dry granulation process, the products here are more resistant to wear. Additionally, the procedure eliminates any changes of clumps in the output, making it easy to disperse and, consequently, dissolve.

Wet granulation, as seen above, is an efficient method of making organic powder fertilizer into granules. The vital aspect is to choose a machine that will work per your needs.
