Rotary drum granulator is a machine which can turn granulate materials into specific shapes. It is suitable for large scale production of cold and hot granulation. What’s more,it is one of key facilities to make compound fertilizer. You can allocate other machines to form a complete compound fertilizer production line. In addition,we have many years of the fertilizer equipment production experience. Therefore, you can trust that we can provide you with quality rotary drum granulation machine at fair price.
Drum granulation Technology
Drum granulator plays a vital role in the process of fertilizer granulation. It is suitable for cold and hot granulation and large-scale production of high, medium and low-concentration compound fertilizers.Due to the wet granulation and large output,our equipment is very popular with owners of large fertilizer production plants.However,what are the attractive features of our rotary drum granulation machine? Then why are they favored by the majority of fertilizer manufacturers?Below, we will reveal the answer for you on the relevant content of the drum fertilizer granulator.
Additives you can use in drum granulation process
During the granulation process, in order to increase the viscosity of the granules, improve the granulation efficiency and agglomeration rate. You can add some binders appropriately to improve the physical properties of the granules.
There are three types of these binders: inorganic (bentonite), natural organic (molasses, starch, fine powder of Konjac, etc.), synthetic organic (CMC, PVA, PAM). If you find it difficult to agglomerate the particles during the granulation process, you can add an binder appropriately. After drying, the solid cross-linking strength is high, improving the viscosity of the granules. And the cost is low. It is an accelerator suitable for granulation.
How to get your targeted fertilizer granular sizes?
When you produce granular fertilizer, there will be fertilizers of different fineness and size. In order to improve the sales rate and the aesthetics of the granules, you can use the fertilizer screening machine to choose the fertilizer requirements that suit your production. The manure screening machine has three outlets, which are too large, too small and finished products. And you can store according to your needs. Then, those substandard fertilizers will be transported to the final step of fertilizer production.
How does rotary drum granulator works?
Its working method belongs to wet granulation. Through a certain amount of water or steam, the raw materials are fully chemically reacted after the humidity is adjusted in the cylinder. Under certain liquid phase conditions, with the help of the rotation of the cylinder, the material particles generate extrusion force to agglomerate into balls.
Why should you choose the fertilizer rotary drum granulation machine?
There are many advantages of the drum granulator. You will not regret it if you choose this equipment under the premise that it is suitable for your production line.
How to reduce the cost of granulation and avoid waste of raw materials?
Since the working principle of the drum granulator belongs to wet granulation, the wet raw materials are easy to stick to the inner wall of the drum. This greatly affects the granulation rate of the equipment. Although the lining is made of rubber to avoid a large amount of fertilizer from adhering to the equipment, we have designed multiple cleaning holes on the granulation drum to maximize cleaning efficiency. During the production of granular fertilizer, with the rotation of the drum, the hammer hits the holes by gravity, and vibration shake off the raw materials on the wall. In this way, you can avoid the problems of large waste of raw materials and low granulation rate effectively. And you can reduce the maintenance cost of the machine .
Auxiliary machines you can use with our drum granulator in production line
If you want the granulation to meet your expectations, then you cannot ignore some equipment on your drum granulation production line.
