Rotary drum granulator is one of the key fertilizer granulation equipment for manufacturing compound fertilizer granules, suitable for cold, hot granulation in high, medium and large scale production. The compound fertilizer granulator can simultaneously produce low concentration and high concentration compound fertilizer particles. . The finishing inside the rotary drum granulator is made of a special polyethylene-resistant rubber sheet. The granulator has the advantages of high compound fertilizer granulation rate, good appearance, corrosion resistance, low energy consumption, easy operation and maintenance. Our multi-functional twin-roll granulator can also manufacture compound fertilizers. Efficient fertilizer granulator is considered to be the most important equipment in large-scale compound fertilizer production. By adding a certain amount of steam and steam, the raw material rotary drum granulator will become even and wet during the granulation process. Then a series of chemical reactions take place. In this rotary granulator, fertilizer granules are pressed against each other and rolled into fertilizer granules. The uniformly formed fertilizer particles can be 3-8 mm. With the continuous addition of raw materials and the rotation of the drum, it will ensure mass production and work efficiency.
Features of rotary drum granulator in organic ferilizer production line
1.The rotary drum granulator has high granulation rate about above 70%,the unqualified granules can be re-granulated;
2.Hot steam improves material moisture,which makes compound fertilizer granulation easy;
3.The compound fertilizer granulator finished inside of polyethylene makes raw materials difficult to stick the body,anti-corrosion insulation.
NPK fertilizer production process:
In npk fertilizer production line
,we can use the rotary drum granulator machine which it is also to be equipped in organic fertilizer production line to finish the production process of the npk fertilizer granulator.The rotary drum granulator machine generally to be used by using the wet granulation method to finish the production process in npk manufacturing process
.This point is different from the double roller granulator machine that it is usually to use the dry granulation method to produce the fertilizer granulator.
