What equipment do you need for establishing a fertilizer granulation line?

Setting up a fertilizer granulation line is easy, provided that you know what kind of equipment to buy. Here are the main machines this production process requires, with details on their importance and on their role in the overall setup of your production line.

The first process is the mixing of the raw material into a homogeneous compound. This step requires a horizontal mixer. The horizontal mixer is a machine that features two opposing rotors that generate a compound motion of the material. The result of this fast and soft mixing process is a continuous loop of material inside the machine. At this stage of the production process, the shape, the size and the density of the raw material make no difference to the outcome. Different horizontal mixers have different stirring speed, motor power, and production capacity.

The granulator is another essential device. A double roller extrusion granulator is probably one of the best solutions, as it enables the production of high quality granules, at the room temperature, and without drying. This type of granulator is compact and efficient. It can help you achieve a continuous production at a specific rate. It can produce high, medium and low concentration fertilizer. If needed, it can allow you to choose the shape and the size of the fertilizer granules by customizing the shape and the size of the ball socket. This feature can be useful in case you want to switch between different types of fertilizer granules to cater to the needs of your different clients.

This type of granulator works at room temperature and it doesn’t dry the material. This is an eco-friendly method, much better than wet granulation. However, each of these methods has its own pros and cons. You need to carefully weigh their benefits and their drawbacks before making your final decision. In your different fertilizer granulation plants, you can choose different granulators for manufacturing.

The rotary screening machine is another important component of the production line. Although the double roller extrusion granulator has good accuracy, there will always be granules that are too big or too small. As this isn’t something your clients will be happy with, you need this screening machine to allow only good granules to pass through. The other ones will return to the beginning of the production process, so you won’t need to put up with any material loss. This step of the fertilizer granulation process is required to ensure the desired quality standard.

The last stage of the process is the packaging of the fertilizer granules. This is an automatic process which requires a double bucket packing scale. This scale weighs the right quantity of product and packs it in accordance with your instructions. This machine allows you to choose the weight and the size of the packs. This makes storage and transportation much easier, and it allows you to offer your clients the type of product that suits their needs.

This is the basic equipment you need to establish a fertilizer granulation line. Depending on your specific requirements, you may need to add some auxiliary devices and machines.
