NPK Grnuales Fertilizer Production

The Way To Produce NPK Granules Using NPK Granulation Machines?

NPK fertilizer granules are produced using NPK granulation machines. When it comes to buying NPK fertilizer granulation equipment, it's crucial that you know that you have two different methods of granulating fertilizer: wet and dry. The dry method utilizes extrusion force to press dry powder into pellets. Meanwhile, when using wet drum pelletizers, liquids must be added to the raw materials to offer an adhesive force for granulating. A dry granulation pelletizer is probably the most essential pieces of equipment within an NPK compound fertilizer production line.

Double Roller Press Machine

This kind of machine produces organic fertilizer pellets using extrusion force and will not require any drying processes. The double roller press pellet machine can function at room temperature and could be used to manufacture fertilizer granules in a variety of shapes and sizes. During extrusion granulation, every one of the raw materials are vigorously aggregated under high pressure. The resulting powder will then be squeezed between rollers to produce granules. Since no drying or cooling of fertilizer granules is essential, double roller extrusion granulators are ideal for small to mid-sized organic fertilizer manufacturing plants who may have limited funds for investment in equipment.

Wet Granulation Technology

Wet granulation brings about fertilizer that has a higher moisture content, and so the end product requires drying, cooling and solidifying processes. The four forms of machines which can be used for wet granulation include rotary drum granulator, spray granulation machine, tower spray granulation machine, and disc pan granulation machine. Furthermore, the liquid added through the wet granulation process must be non-toxic and volatilizable. Common additives used are isopropanol and ethyl alcohol. The liquid has to include binders otherwise the very last product will separate during the drying process.

Disc Pan Granulation

The benefits of a disc pan granulator are that it is a lot less than a rotary drum granulator and it has a variety of applications. The disk is made out of strong iron material, rendering it durable and stable. The within the pan is coated within an anti-corrosion plastic glass lining, that is very easy to maintain. During operation, the device produces little noise and is recognized for its reliability. Disc pan granulators are utilized in compound fertilizer production lines that manufacture 50 plus,000 plenty of fertilizer pellets each year.

Finishing Processes

After granulation, you will find additional processes required to complete NPK fertilizer production. If a wet granulating machine was adopted to make the pellets, drying and cooling processes are needed. You can buy drying machines specifically designed for drying and cooling NPK fertilizer granules.

Another stage will be the screening process. In that process, unqualified pellets are removed and sent back for the crushing area of the production line. You could buy different screeners according to your sieving specifications.

The coating process follows the screening process and is also employed to give fertilizer granules a smoother finish in addition to improving their physical characteristics. The packing process is definitely the final stage of production. To boost production efficiency, most companies put money into automatic weighing and bagging machines.
